In the analogy of a rainbow chocolate chip cookie, what do the chocolate chips represent?

What type of rocks are formed by intense heat and/or pressure?

Back

Front

What are rocks primarily composed of?

Back

Rocks are primarily composed of minerals.

Front

What are sedimentary rocks?

Back

Front

What is the difference between intrusive and extrusive igneous rocks?

Back

Intrusive igneous rocks form from magma that cools slowly beneath the Earth's surface, while extrusive igneous rocks form from lava that cools quickly on the surface.

Front

What is mineral cleavage?

Back

Mineral cleavage is the tendency of a mineral to break along flat, even surfaces.

Front

What is the Mohs scale?

Back

The Mohs scale is a scale used to measure the hardness of minerals, ranging from 1 (talc) to 10 (diamond).
