The Glass

hlaklwb3 — 2021-11-04 07:42:32 UTC

Glass is a hard material that can be made in many shapes. It is usually transparent, but it can also be made in colours. Glass is mainly made of silica; glass made of silica only is called silica glass.

A glass ball with coloured glass shapes inside

Edo-Kiriko, a traditional cut glass craft in Asakusa, Tokyo, Japan. The glass has two layers, a coloured layer outside a clear layer.
Glass used to make windows and bottles is a specific type called soda-lime glass, composed of about 75% silicon dioxide (SiO2), sodium oxide (Na2O) from sodium carbonate (Na2CO3), calcium oxide, also called lime (CaO), and several minor additives.

By changing the proportions, and adding different ingredients, many kinds of glass can be made. Coloured glass is made by adding small amounts of metal oxides. For example, a blue colour is given by tiny amounts of cobalt oxide.

Crystal glass is made by adding lead and zinc oxides. It is not actually a crystal because all glass is a non-crystalline solid. Crystal glass is called cut glass if it has been cut by hand:

Glass is an inorganic solid, usually transparent or translucent, hard, brittle, impermeable to natural materials. Types of glass vary widely according to their components and physical properties Glass can be divided into two types: Ordinary ie soda-lime glass, silica, and specific glass. Ordinary glass is the most productive and consists of sand, lime and soda. The need to use metallic glass in electrical transformers, golf clubs, and other applications has become an urgent matter, which prompted Todd Half Nagel, a university researcher at John minerals Hopkins University and Professor of Materials Science and Engineering, to search for a new glass that has the characteristics of strength, flexibility and magnetic properties. Whereas, metallic glass is formed during the same process into an amorphous form where it is arranged randomly.

A carat is a modern unit of weight for gemstones like diamonds. It is defined as 0.20 grams. This means that a diamond weighing 100 carats would be 20 grams. The modern word, “carat,” goes back to Arab jewelers who used to weigh their precious stones. A typical carob seed is about 0.20 grams, so the same diamond would weigh just the same as 100 carob seeds.

The Carat

2021-11-11 18:09:24 UTC

The carat (as a unit of mass) is a measure used to measure the masses of gemstones, diamonds, and pearls. One carat equals 200 milligrams, or in other words, one gram equals 5 carats.
The word carat came from the Greek word (κεράτιον), which means carob fruit, because the carob seeds were used to measure the masses of gold and precious things.
The metric carat is the international unit used to measure the weight of gemstones. Adopted in 1907 in the Fourth General Conference on Weights and Measures, it weighs 200 milligrams or 0.2 grams, and it equals 3.086 tablets per scale.
( troy grains ) or adjusted 0.00705 (ounce) in the (avoirdupois) scale.

Describe the formation process of salt fingers in 2 paragraphs. (See link below.)

Ahmad works as a scientific researcher at a big and famous company for research. He was chosen as the scientist of the month for his important discovery in the Dead Sea. He discovered massive salt crystal fingers that are formed at the bottom of the Dead Sea. Ahmad noticed tiny fingers that interact with each other as they move down and form larger structures. His discovery enables other researchers to explain this phenomenon of having those salt crystal fingers.

salt fingers

The new study, which was published on May 3 in the journal "Water Resources Research" and was prepared by researchers from the University of California, Santa Barbara, suggests that the small disturbances caused by the movement of waves in the Dead Sea create fingers of salt that slowly transport salt to the bottom.

According to the study, these salt fingers are too small at first to be noticed, but they quickly interact with each other as they move down, forming larger and larger structures, and the size of the fingers may be a few millimeters or only a few centimeters at first, but they are everywhere on the planet.

Hypnotic salty fingers sit on the bottom of the Dead Sea

New research explains why salt crystals are piling up on the deepest parts of the Dead Sea’s floor, a finding that could help scientists understand how large salt deposits formed in Earth’s geologic past.
The Dead Sea, a salt lake bordered by Jordan, and the West Bank, is nearly 10 times as salty as the ocean. Humans have visited the Dead Sea for thousands of years to experience its purported healing properties and to float in its extremely dense, buoyant waters, and mention of the sea goes back to biblical times.
Scientists have worked out what causes massive salt crystals to build up and wave like fingers at the bottom of the world's saltiest lake. They say tiny disturbances in the Dead Sea - which is nearly 10 times saltier than the ocean - create “salt fingers” that slowly deposits down to the lakebed. While shedding light on the physics of the Dead Sea, the findings also help researchers understand the formation of massive salt deposits found within Earth's crust.

C - I will write 2 paragraphs about similarities and differences between the structures of animal cell and plant cell, using the vocabulary I learnt and the comparative/ superlative forms (e.g., Plants cells are usually larger than animal cells).

(Comparison of plant and animal cells)

The plant cell contains plastids, a
central vacuole, and the cell wall, while the animal cell lacks these components.
Animal cells are connected units that allow fluid movement more than plant cells, as they are strongly connected to other plant cells by cell walls.
Animal cells, when present as individual units, can move freely through the organism when necessary, but plant cells remain fixed in place.
Plant cells depend on themselves for food, through the processes of photosynthesis, to which cell walls, central vacuoles and chloroplasts contribute.
The plant cell is oval in shape, while the animal cell is rectangular in shape.
The plant cell contains a central vacuole that makes up about 90% of the cell, while the animal cell contains two or three small vacuoles.
A plant cell contains centrioles of certain types, while in an animal cell, centrioles are present in all cells.

Animal cells

Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts:

Nucleus – This contains genetic material (DNA), and controls the cell's activity.
Cell membrane – A flexible layer that surrounds the cell and controls the substances that enter and exit.
Cytoplasm – A jelly-like substance where the chemical reactions happen.
Mitochondria – This is where energy is released from the food molecules.

Plants are also made up of millions of cells. Plant cells have a nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures:

Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.
Vacuole – A space inside the cell that is used to store substances and help the cell keep its shape.
Chloroplasts – Structures that contain the green pigment chlorophyll, which are a key part of photosynthesis.

💙blue cave
The Blue Cave, when you visit its blue cave, you will be amazed!!! I assure you of that, because everything in it does not just cause astonishment, but also comfort, purity, pleasure, pleasure and wonder.
The way to enter it is a bit strange, as you will enter while lying on your back, on a small boat, carrying only four people, because the opening of the cave is small, two meters wide and one meter long.
It is a natural cave, with a full length of 60 meters and a width of 25 meters, located in the Sea of Capri in Italy. The secret of its blue color is due to the sun's rays that enter through one of its underwater openings, just in front of the cave entrance, and when the light passes through the water, The rest of the colored rays are filtered, and only the blue rays that enter the cave remain.
As for the famous silver reflections, which the cave is famous for, they are due to small aquatic organisms, which cause air bubbles, covering the outer surface of the underwater bodies, which cause a different reflection of light, making them appear in this dazzling silver color.
It is preferable to visit it between noon and two in the afternoon, in order to penetrate a strong ray of light, which allows for an amazing view of the cave from the inside.
It takes time to enter the cave, especially during the tourist seasons, but its visit on the boat does not take more than five minutes, but with a full cruise that can take a maximum of two hours. It is not allowed to dive or swim, because this is a dangerous matter with unsafe consequences.
It dates back to the Roman era, when it was used as a sea temple for worship, and there are still some ancient Roman monuments and statues, which are now displayed in the "Ana Casa" square in the city of "Ana Capri".
It is reported that the cave was deserted for several years, and no one approached it, because of the legend that spread around it, that demons inhabit it, but in 1826 AD, a sailor took the German writer “Auguste Kpech” and the painter “Ernst Fries” to the cave, whose stories and observations helped From the splendor of the Blue Cave to everyone's desire to see and explore it.

Snowboarding is believed to have originated in the United States. Though its origins are sketchy, and plenty of children and adults can claim to have stood up on a flat surface of some sort and slid down their local sled hill, there are several names, dates, and inventions that are agreed-upon highlights in the most common histories of the sport.Snowboarding, a winter sport with origins in skiing and surfing where the primary activity is riding any snow-covered surface while standing on the skateboard with feet placed almost perpendicular to the board, which distinguishes it from skiing, moreover, no poles are used As in skiing, the majority of participants do not wear hard but soft to medium bending shoes for support. The sport developed in the 1960s and 1970s, its popularity increased in the 1980s, and became an Olympic sport in 1998. For enthusiastic riders around the world, snowboarding is a special kind of "medicine for the soul, combining the beauty of nature with the excitement of competition and the opportunity to express There is no single way to ice skate

Waitomo Cave, the night
light, is one of the enchanting natural wonders, and a dazzling tourist attraction in New Zealand, with a lifespan of 30 million years. Millions of worms, yes worms are the main light source for this beautiful cave. Glowworms glow worms that keep it going during the day all day long The strange cave is famous for that its ceiling is like a chandelier or a huge chandelier in which millions of glowworms live, as they spread widely in the cave and were the cause of this wonderful lighting for it. The more worms multiply, the brighter the cave.
Imagine that creatures that most of us consider revolting, such as worms, are the source of all this beauty and fascinating light, but it is the truth.

Just two hours north of Sydney, this magical sea grotto at Deep Cave Bay can be found a short stroll from the end of Moonee Beach in Munmorah State Conservation Area. As you approach, you'll notice the mouths of rockpools are tinged with a fleshy hue, but this is nothing compared to the sea channel that flows into the main cave system, which blushes a vivid shade of bubble-gum pink. This vibrant color also has the effect of turning the waters a particularly dazzling shade of turquoise. And it's not just the sight of these rosey caverns that are worth a visit. When the tides push the incoming waves through the cave's central channel, the thunderous sound reverberates around the rocks, amplifying the rumble as it travels deeper into the system. It goes without saying that you'll want to take a few snaps to capture these caves in all their technicolour glory, but there are also plunge pools near the cave's entrance if those azure waters look too inviting.
