Unit 3 Pre test

Front

What type of rock forms when lava cools and solidifies?

Back

Igneous rock

Front

What are seismic waves?

Back

Seismic waves are energy waves that travel through the Earth, produced by geological events.

Front

How are sedimentary rocks formed?

Back

Through the processes of compaction and cementation.

Front

What is the difference between P-waves and S-waves?

Back

P-waves are faster and can travel through solids, liquids, and gases, while S-waves are slower and can only travel through solids.

Front

What are the primary components of the Earth's core?

Back

Iron and nickel.

Front

What is the process of compaction in sedimentary rock formation?

Back

Compaction is the process where sediments are pressed together under pressure.

Front

What is cementation in the context of sedimentary rocks?

Back

Cementation is the process where dissolved minerals crystallize and bind sediments together.

Front

What are the two main types of igneous rocks?

Back

Intrusive (plutonic) and extrusive (volcanic) rocks.

Front

What is the significance of seismic waves in geology?

Back

Seismic waves help geologists understand the Earth's internal structure and the location of earthquakes.

Front

What is the composition of the Earth's mantle?

Back

The mantle is primarily composed of silicate minerals rich in iron and magnesium.
