Definition: A mineral is an inorganic, homogeneous solid

Inorganic means never been alive

Homogeneous means made of only one thing

Three types of rocks

Igneous - May have crystals, no layers, may have holes, might look “glass-like”

Metamorphic - May have layers of crystals or minerals, wavy lines

Sedimentary - May have layers, rounded particles, rough and grainy

Deep inside the Earth, rocks and minerals melt under tremendous heat. This forms magma.

When the magma cools back down, it hardens and forms new rocks. These rocks are called IGNEOUS rocks.

Some rocks are changed by heat and pressure. New rocks are formed.

The forces of wind, water, and gravity break rocks down into little pieces. This is called weathering.

After a long time, these little pieces of rocks get stuck back together and form new rocks.

Soil Formation

It takes about 500 years for 1 inch of topsoil to form.

Soil is formed as rocks are weathered and

covered with organic material.

Erosion happens when pieces of rocks and soil are carried away by wind and water.
