Version 1 HMH Science Module F Lesson 3 & 4 Flashcard

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move toward each other, often causing one plate to be pushed under another, leading to geological features like mountains and earthquakes.

Front

What happens at point B in the oceanic crust?

Back

At point B, one tectonic plate is being pushed under another plate, a process known as subduction.

Front

Which evidence does NOT support the theory of continental drift?

Back

Current weather does not provide evidence that continents have drifted to their present locations.

Front

What is a direct result of tectonic plate movement?

Back

The formation of mountain ranges is a direct result of the movement of tectonic plates.

Front

What causes a sharp jagged mountain to become smoother over time?

Back

Weathering and erosion are responsible for smoothing out sharp jagged mountains over time.

Front

What is sea floor spreading?

Back

Sea floor spreading is the process by which new oceanic crust is created at mid-ocean ridges as tectonic plates pull apart.

Front

What is the definition of tectonic plates?

Back

Tectonic plates are large sections of the Earth's lithosphere that move and interact with each other, causing geological activity.

Front

What is subduction?

Back

Subduction is the process where one tectonic plate is forced under another plate, often leading to volcanic activity.

Front

What are fossils, and how do they support continental drift?

Back

Fossils are remains of ancient organisms. Similar fossils found on different continents suggest that these continents were once connected.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces due to environmental factors like wind, water, and temperature changes.
