What is weathering?
Weathering is a long and slow process, which breaks down rocks and minerals into small pieces. This can happen through water, wind, temperature change, and plant life.

What are ways in which we people can control erosion?
windbreaks planted along fields, steps or terraces, add mulch or rocks, plant shrubs, plant trees.
How is metamorphic rock formed?
metamorphic rock is formed when intense heat and pressure are applied onto igneous and sedimentary rocks and the rocks change form.
How are fossils formed?
Fossils are found in sedimentary rock, over time the layers squeeze together and harden, the remains of plants and animals can be buried in this. Over time the plant material, skin and flesh rot away and what is left is an imprint of a plant or bones and teeth of the animal.
What are mined underground?
Potash, gold, coal, and uranium can be mined underground.
Wind carries dust and sand that gradually wear down the surface of rocks and break off particles to add to soil. Running water also wears away at rocks to break off tiny bits. The roots of growing plants can break off smaller bits of rock from larger rock formations.
