Quarter 2 Exam Review

Front

What are P waves?

Back

P waves, or primary waves, are the first waves released during an earthquake. They are compressional waves that travel through solids, liquids, and gases.

Front

What are spring tides?

Back

Spring tides occur when the Earth, moon, and sun are in a straight line, resulting in higher high tides and lower low tides.

Front

What are neap tides?

Back

Neap tides occur when the moon and sun form a ninety degree angle with the Earth, resulting in lower high tides and higher low tides.

Front

What is the crest of a wave?

Back

The crest is the top point of a transverse wave, where the wave reaches its maximum height.

Front

What geologic events occur at mid-oceanic ridges?

Back

Earthquakes and volcanic eruptions occur most often at mid-oceanic ridge plate boundaries.

Front

What happens at convergent boundaries?

Back

At convergent boundaries, tectonic plates collide with each other.

Front

What are S waves?

Back

S waves, or secondary waves, are seismic waves that travel through solids and are slower than P waves.

Front

What is a transverse wave?

Back

A transverse wave is a wave in which the motion of the medium is perpendicular to the direction of the wave's travel.

Front

What is a trough in a wave?

Back

A trough is the lowest point of a transverse wave, opposite the crest.

Front

What is the difference between oceanic and continental plates?

Back

Oceanic plates are denser and thinner than continental plates, which are thicker and less dense.
