Unit 3 mid unit review

Front

What are hot spots in geology?

Back

Hot spots are volcanic regions that are not located at plate boundaries, where magma rises from deep within the Earth's mantle to the surface.

Front

What geological features are found on both sides of the Atlantic Ocean?

Back

Mountain ranges that have the same rock types, structures, and ages.

Front

What type of seismic waves arrive at a seismograph first?

Back

P waves (Primary waves) are the fastest seismic waves and arrive first at a seismograph.

Front

What geological feature is created by convergent plate movement?

Back

Mountains are formed when tectonic plates collide and push against each other.

Front

What is the silica content of mafic magma?

Back

Mafic (dark-colored) magma has a low silica content.

Front

What are the characteristics of P waves?

Back

P waves are compressional waves that can travel through solids, liquids, and gases, and they are the fastest seismic waves.

Front

What is the difference between mafic and felsic magma?

Back

Mafic magma is low in silica and dark in color, while felsic magma is high in silica and light in color.

Front

What is a convergent boundary?

Back

A convergent boundary is where two tectonic plates move toward each other, often resulting in mountain formation or subduction.

Front

What are the three types of plate boundaries?

Back

The three types of plate boundaries are convergent, divergent, and transform boundaries.

Front

What is the significance of mid-ocean ridges?

Back

Mid-ocean ridges are underwater mountain ranges formed by tectonic plates pulling apart, creating new oceanic crust.
