What did we learn

I like what we are learning about but maybe we could learn more about nature. BY: LAILA

Erosion means carrying away and weathering means breaking. and now I will tell you about a rock cycle. It starts like this, the magma inside a volcano gets out side the volcano and then it cools down to igneous rocks. After that I`am pretty sure that weathering and erosion turns the igneous rocks into tiny particles called sediments. Then compaction and cementation turns the sediments into sedimentary rocks. Then the sedimentary rocks change to metamorphic rocks which melts to magma again.

The rock cycle Shakirah

2014-06-20 04:57:00 UTC

The first thing that happens is the volcano erupting. When it erupts, lava comes out and when it cools down it turns into an igneous rock. After, the igneous rocks are weathered and eroded and turned into sediments. They then push together and become sediments. Next, they melt and become metamorphic rocks. Then the metamorphic rock turns into magma and the rock cycle starts all over! Plus it takes 500 years to make a centi metre of soil!

Soil is interesting and is fun to learn about! Amina

The rock cycle Mirza

2014-06-20 04:59:25 UTC

The rock cycle starts of with magma then the magama gets cooled down to form igneous rocks then the igneous rocks get weathered and eroided to form sediments.The next part of the rock cycle is the sediments get combined to form sedementary then the sedimentary rocks get pressure and heat to form metamorphic rocks. The last part is that the cycle starts again.

I love this "changes in the environment"

THANK YOU!

Soil is made out of rocks or leaves in 500 years.

I like what we are learning about. Before I thought rocks were boring!

name of weathering

Weathering is breaking down.

I love the soil one because it told us how important soil is.

Hanah: Learning about the rock cycle is really interesting.

SOIL

2014-06-20 05:14:33 UTC

SOIL IS INTERESTING FOR ALL BUT I THINK PEOPLE DON'T THINK SO . BUT SOIL IS SOMETHING TO TAKE CARE OF NOT LIKE A PET WHO WOULD HAVE SOIL FOR A PET SO WHAT I WAS SAYING IS USE SOIL FOR GOOD USE OKAY.

2014-06-20 05:14:34 UTC

changes in the environment can be good or bad,like this one this environment is good and bad for us. The good thing about it is that we have a place to live in, the bad thing is that there wont be that much nature and our world will be polluted. made by khayru

I like to clean the environment. ^_^

Zakaria

2014-06-20 05:19:31 UTC

The rock cycle is very cool ^_^

soil is ... Shakirah

2014-06-20 05:22:14 UTC

Soil is very valuable and interesting. It is also very important, it helps the plants grow and other important stuff...

Changes in the environment

2014-06-20 05:22:23 UTC

Our environment changes lots of times from nature to small villages which end up becoming huge cities.

Weathering Mirza

2014-06-23 01:53:39 UTC

Wearthering is another word for breaking down. Rocks get softer by water. When the rock gets softer by the temperature from the sun, year by year the rock gets breaking down or weathered then erosion takes over.

Can we learn a bit more of wildlifeBy:Laila

Weathering Shakirah

2014-06-23 01:58:45 UTC

Weathering is the breaking down of rocks by

plant roots, frozen water, wind, temperature

and pressure.

I realised that when we use soil and rocks, use it kindly and wisely. We don't use it for playing, when we were learning about soil. I learnt that for one centimetre of soil to grow it takes 500 years. When we learnt about rocks, I didn't know a thing. Then we learnt and I now know that there are different rocks- metamorhpic rocks, igneous rocks and more and I'd like to thank Miss Manju for teaching. Thank you, Miss Manju for teaching me. hank you a lot.

Can we learn more about crystal rocks? By:Laila

Erosion Shakirah

2014-06-23 02:04:53 UTC

Erosion is the carrying away of rocks by

wind or water.

Ibrahim

Soil is important because it helps the plant make food and we eat that food so we depend on it for our survival.

Erosion- Mirza

2014-06-23 02:09:49 UTC

Eroson is another word for take away. When the rocks get weathered, there are tiny tiny pieces of rocks that get weathered.The little tiny pieces get eroded, then it goes again.

How long does it take Shakirah

2014-06-23 02:12:11 UTC

It takes 500 years to only grow1 cm of soil!

Threats to the the environment Shakirah

2014-06-23 02:15:58 UTC

Pollution is very harmful to the environment,

it changes the way rivers look and plants grow

and can make the polluTed thing dangerous for

example if it pollutes a river it can coat a duck

that swims in it in oil and suffocate it.

Khayru

2014-06-23 02:16:02 UTC

We can balance our environment by not making too many buildings and deforestation.

Azeezah

2014-06-23 02:18:01 UTC

Without the rock cycle we wouldn't

have soil.

Some animals die because of changes in the environment like when people build huge cities in places where lots of animals live and then they die.

Logging can doom - Shakirah

2014-06-23 02:24:28 UTC

Logging takes away the homes of many creatures and destroys many trees that provide air and absorbs CO2

Environment helps us Shakirah

2014-06-23 05:05:55 UTC

The environment has trees that absorb CO2 and give us air.

They have rivers that quench our thirst and water our plants.

And the sunlight which we need for vitamin D but some people don't care.

Sharmarke, the environment saver

2014-06-23 05:15:16 UTC

The environment is very important

and we need to help.

Changes in the envinment

2014-06-23 05:18:27 UTC

Our environment is created by Allah. We have to stop killing them by stopping polluting water and killing sea animals and those sea animals are Allah's creations. We also have to stop the deforestation and logging because animals such as birds and tree frogs are becoming endangered. All these animals are Allah's creations so we should stop deforestation, logging and polluting to save Allah's creations.

Lava- Shakirah

2014-06-23 05:20:48 UTC

When lava is in the volcano it's called magma and when it's outside the volcano it's called lava.

When lava or magma cools down or dries, it becomes an igneous rock. An igneous rock is a rock made of lava or magma and can be of two different types, obsidian and basalt.

I wonder how old the oldest rock is in the world.By:Laila

2014-06-23 08:29:06 UTC

Khayru

2014-06-24 09:48:29 UTC

Igneous rocks are one of the three main rocks, it is made by cooling or solidifications of lava or magma

Khyaru

2014-06-24 09:55:58 UTC

Metamorphic rocks arise from the transformation of existing rock types, in a process called metamorphism, which means "change in form". The original rock is changed in colour by heat and pressure.

We need to help animals. Logging can doom usssss!
