This is my homework:
Igneous Rock Facts
There are over 700 different types of igneous rocks.
Magma can be forced into rocks, blown out in volcanic explosions or forced to the surface as lava.
Here are some examples of igneous rocks
This is a Igneous Rock:
Do soils come in different colours?
Yes, Soils do come in different colours. They don’t come in rainbow colours they come in black, yellow, white, brown and grey.
What does the weather do to soil?
Whether you believe it or not, weather helps make soil. When the weather gets hot, rocks can get bigger. When the weather turns cold, rocks can get smaller. If this happens often enough, the rock will crack and break up into small pieces that break into even smaller pieces. When they get really small they turn into soil. Rain and ice can also get into rocks and break them apart. So, believe me, the weather does help make soil.
How does water stay in the soil?
When water gets into the soil, it pours into pores. Pores are spaces in the soil that come in different sizes. The bigger the pore, the more water it holds.
How does air get into the soil?
Air gets down into the soil through the same pores that let in and hold water.
Do roots just help plants?
Roots love helping others. They drain water from the soil. That keeps the soil from staying too wet. And when the soil gets too dry, roots draw up water. This water has all kinds of good stuff in it that living things need to stay healthy. Roots help make soil, too. They split rocks into pieces that later become soil.
I hope you learnt something about rocks and soils.
