Final Exam 9th Grade Science Part 2

Front

What is a convergent plate boundary?

Back

A convergent plate boundary is where tectonic plates move towards each other.

Front

What is the focus of an earthquake?

Back

The focus is the point within the Earth where an earthquake begins.

Front

What is a divergent boundary?

Back

A divergent boundary is where tectonic plates move away from each other.

Front

What is the difference between P-waves and S-waves?

Back

P-waves (primary waves) are compressional waves that travel faster than S-waves (secondary waves), which are shear waves.

Front

How do scientists measure the magnitude of an earthquake?

Back

Scientists measure the magnitude of an earthquake using a seismograph.

Front

What is the epicenter of an earthquake?

Back

The epicenter is the point on the Earth's surface directly above the focus of an earthquake.

Front

What are seismic waves?

Back

Seismic waves are waves of energy that travel through the Earth, typically caused by earthquakes.

Front

What is a fault in geology?

Back

A fault is a fracture or zone of fractures between two blocks of rock.

Front

What is the significance of the Richter scale?

Back

The Richter scale is a logarithmic scale used to measure the magnitude of earthquakes.

Front

What happens at a transform boundary?

Back

At a transform boundary, tectonic plates slide past each other horizontally.
