Unit 2 Review: Geological Processes

Front

What are lithospheric plates?

Back

Lithospheric plates are large sections of Earth's lithosphere that move and interact with each other, making up the Earth's surface.

Front

How many lithospheric plates are there approximately?

Back

There are approximately 70 to 80 lithospheric plates that make up Earth's surface.

Front

What is metamorphic rock?

Back

Metamorphic rock is a type of rock that has been changed from its original form due to heat and pressure over millions of years.

Front

What processes lead to the formation of metamorphic rock?

Back

Metamorphic rock forms when existing rock is subjected to heat and pressure, causing physical and chemical changes.

Front

What was Pangea?

Back

Pangea was a supercontinent that existed hundreds of millions of years ago, which eventually split apart to form the continents we know today.

Front

What evidence do scientists use to understand Earth's layers?

Back

Scientists measure seismic waves generated by earthquakes to determine the composition, state of matter, and temperatures of Earth's layers.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, often generated by earthquakes, and are used to study the Earth's interior.

Front

What materials were used in the plastic tubes in Act 2: Investigating Groundwater?

Back

The materials used were sand and clay.

Front

How does heat and pressure affect rock formation?

Back

Heat and pressure can cause minerals in rocks to recrystallize, leading to the formation of metamorphic rocks.

Front

What is the significance of studying lithospheric plates?

Back

Studying lithospheric plates helps us understand geological processes such as earthquakes, volcanic activity, and continental drift.
