Earth Materials

This term refers to the disintegration and decomposition of rock's physical and chemical composition on the Earth's surface.

This term refers to the changes of rock's appearance due to changes in pressure and temperature.

This refers to the tendency for particles to settle in liquid.

It refers to the process of removing Earth materials from their original sites through weathering and transport these materials to a new location.

This refers to the remains and traces of plants and animals that are preserved in rocks.

What type of rock is formed by cooling and crystallization of hot, molten rock material called magma?

• Sdimentary rocks

• Metamorphic rocks

• Igneous rocks

Which type of rock is common at the surface of the Earth?

• Sedimentary Rocks

• Metamorphic Rocks

• Igneous Rocks

What are the main factors of the formation of metamorphic rocks?

• changes in weather

• heat and pressure

• heating of magma

Which of the following are the types of sedimentary rocks?

• Clastic and Nonclastic

• Foliated and Nonfoliated

• Intrusive and Extrusive

How do extrusive igneous rocks differ from intrusive igneous rocks?

• Extrusive igneous rocks are formed from solidified magma underneath the earth while Intrusive igneous rocks are formed from solidified lava at or near the surface of the earth.

• Intrusive igneous rocks are formed from solidified magma underneath the earth while Extrusive igneous rocks are formed from solidified lava or at near the surface of the earth.

• Extrusive rocks have slow cooling or crystallization while Intrusive igneous rocks have fast rate of cooling/ crystallization.
