1.) New minerals began to from because of the intense heat that turned our Earth from being black in color to being gray.
2.) Earth cooled down and allowed for liquid water to form and turn Earth blue about 4.3 billion years ago. This was proven with the discovery of zircon that was produced only in an environment where liquid water was present.
3.) Amino Acids were formed with the presents of water, gases, and electricity which then created proteins.

Trilobites are ancient, extinct, marine arthropods

The Miller Urey experiment stimulated conditions on earth before life. Materials used include water, estimated gases from early atmosphere, and electricity. The brown goo is significant because it provided evidence that organic matter can derive from inorganic matter since it was made up of amino acids.

The formation of minerals was an important change that affected life on Earth because it changed the Earth from black to gray.

# data[].attributes.body
Trilobites are arthropods that are extinct. They are not the oldest form of life on Earth. They're the oldest fossils found because they were one of the first organisms with a shell.

# data[].attributes.body
It attempted to stimulate the conditions present on early Earth to form life. They used water, ammonia, and hydrogen to stimulate the conditions. The brown goo was organic compounds. Specifically amino acids. This experiment showed that life could be made from inorganic molecules.

Stromatolites are a build up of lime(fossils) These are important in the history of the Earth to show us how species have evolved.

# data[].attributes.body
Minerals were created because of the strong heat that changed the black color of the earth to the color grey.
The earth also was able to then cool down to create water and turn the earth blue.

They are marine arthropods. They are one of the earliest life forms. This is because they were one of the earliest creatures with bones.

# data[].attributes.body
It stimulated the conditions on earth before there was life. The materials used were water, methane, ammonia, and hydrogen. The brown goo is significant because it shows that organic matter can come from inorganic matter.

Stromatolites are built up calcified mounds of lime that secretes cyanobacteria and sediment, found in Precambrian rocks as the earliest known fossils.

# data[].attributes.body
New minerals were created/began to form. This caused a change the color of the earth from black to gray. Earth then cooled down, which allowed blue water to form.

1. Molten lava cools down and earth eventually reached a temperature that could sustain life.
2. Water somehow formed which is a good solvent and therefore provided a place for dissolved elements and minerals to interact.

Fossils of marine life- they are one of the earliest forms of life but not the earliest.

# data[].attributes.body
It simulated what earth was like before there was life. It used water, gas and a spark. This goo was organic compounds associated with life like amino acids which code for proteins. So we needed these for life.

# data[].attributes.body
Stromatolites are lime that has been built up over time, and they are significant because they are one of the oldest fossils to give evidence to the history of life on earth.

Water in the form of Zircon shows that life was on earth 3 billion years ago.

Trilobites are arthropods that are extinct.  They are one of the earliest life forms on Earth.  They were one of the earliest creatures with bones, which is why they are the oldest fossils.

# data[].attributes.body
It stimulated the way the Earth was before life had inhabited it. The chemical origins of life as we know it was then used to test whether or not they thrived in those conditions. The brown goo was important because it was an organic compound (amino acids) which indicated life.

# data[].attributes.body
Stromatolites are formed when there is a build up of minerals and are found in early rock formations and modern habitats in the ocean.

# data[].attributes.body
Minerals forming was important because it changed the color of earth from black to gray. When earth cooled, liquid water came.

# data[].attributes.body
They are the oldest form in bacteria on Earth. They are the oldest fossil because they were made from shells. Shells fossilize better than soft shelled organisms.

# data[].attributes.body
The Miller Urey Experiment simulated earth before there was life. Water, gas, an electric spark, as well as a flask, were used to simulate this. The brown goo that formed was significant because it revealed amino acids (which are shown in life).

Stromatolites are lime deposits that calcified over time, and they are considered the first of fossils.

Once the molten surface of the earth cooled down, it became cool enough that life could form.

This experiment simulated the ocean and the atmosphere of early Earth. The materials used were a spark, flasks, water, and gasses. The brown goo was the organic compounds being covered with amino acids.

Stromatolites are build up of lime. These are significant because they are the first fossils. This means they are able to show how things have evolved.

Minerals began to form on the black earth turning it grey, then earth cooled and water formed and the earth turned blue. After these changes earth was more sustainable for life.

It simulated what Earth was like a long time ago. He used Methane, Ammonia. The brown goo made amino acids and this is significant because amino acids make proteins.

The formation of minerals and organic compounds that make life. Also water which helps sustain life.

The experiment and its materials simulate early "before life" Earth conditions. Water was used to simulate the ocean, gases were used to simulate the air in the atmosphere, and the spark was used to simulate lightning on Earth. The brown "goo" that formed was a composition of amino acids. This is extremely significant because  amino acids are the building blocks of proteins, and proteins are necessary in the formation of cells. Cells are the building blocks of all life. Therefore, amino acids must be present to create life.

Stromatolites are mounds built up of lime. They're significant because they are some of the earliest fossils which shows us a lot about our early earth.

# data[].attributes.body
The formation of water provided a place for minerals and other molecules to interact, given it is the universal solvent.

The electricity simulated lightning that broke down molecules that are considered necessary for life.

Stromatolites are lime deposits that have hardened over time. They are some of the earliest fossils, so they can tell us a lot about the history of the earth.

Stromatolites are mounds of built up layers of lime and trapped sediment. These stromatolites are used to show evidence of early life. The stromatolites found in Australia show what the ocean floor looked like billions of years ago.
