Unit 7 - 7.10A 7.10B Flashcard

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often causing earthquakes and mountain formation.

Front

What is magma?

Back

Magma is melted rock that is found beneath the Earth's surface.

Front

According to the law of superposition, where are the oldest fossils found?

Back

The oldest fossils are found near the bottom of the rock layers.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move apart from each other, often creating new crust.

Front

What evidence supports the theory of continental drift?

Back

Fossils of palm trees found in cold regions suggest that continents have moved over time.

Front

What happens at a transform boundary?

Back

At a transform boundary, tectonic plates slide past each other, which can cause earthquakes.

Front

What is the significance of the law of superposition in geology?

Back

The law of superposition helps geologists determine the relative ages of rock layers and the fossils within them.

Front

What are tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact at their boundaries.

Front

How do earthquakes occur?

Back

Earthquakes occur when stress builds up along fault lines and is suddenly released, causing the ground to shake.

Front

What is the role of glaciers in fossil distribution?

Back

Glaciers can transport fossils over long distances, which can lead to their discovery in unexpected locations.
