12/20: Winter Break Assignment part 2

Front

What are P-waves?

Back

P-waves, or primary waves, are seismic waves that travel through the Earth's interior and can move through solids, liquids, and gases.

Front

What are S-waves?

Back

S-waves, or secondary waves, are seismic waves that can only travel through solids and cannot move through liquids or gases.

Front

What is a divergent boundary?

Back

A divergent boundary is a tectonic plate boundary where two plates move away from each other, often resulting in the formation of new crust.

Front

What is a convergent boundary?

Back

A convergent boundary is a tectonic plate boundary where two plates move toward each other, often leading to one plate being forced beneath another.

Front

What is a transform boundary?

Back

A transform boundary is a tectonic plate boundary where two plates slide past each other horizontally.

Front

Where is the oldest rock typically found?

Back

The oldest rock is usually found at the edges of tectonic plates, particularly at divergent boundaries where new crust is formed.

Front

What happens at a convergent boundary?

Back

At a convergent boundary, tectonic plates collide, which can cause earthquakes, volcanic activity, and the formation of mountain ranges.

Front

What happens at a divergent boundary?

Back

At a divergent boundary, tectonic plates move apart, leading to the creation of new oceanic crust and mid-ocean ridges.

Front

What is the significance of P-waves in seismic studies?

Back

P-waves are significant because they are the first waves detected by seismographs, providing crucial information about the Earth's interior.

Front

What is the role of S-waves in understanding Earth's structure?

Back

S-waves help scientists understand the composition of the Earth's interior, as their inability to travel through liquids indicates the presence of liquid layers.
