Front

What are planetesimals?

Back

Planetesimals are small celestial bodies that are in the process of forming into planets through the process of accretion.

Front

What type of plate boundary is characterized by two plates sliding past each other?

Back

Transform plate boundary.

Front

What type of eruption is associated with high silica content in volcanoes?

Back

Explosive eruption.

Front

What is the plastic layer of the mantle called that allows the lithosphere to move?

Back

Asthenosphere.

Front

What do we call rock layers that are correlated by containing the same fossils?

Back

Fossil correlation.

Front

What is the definition of a convergent plate boundary?

Back

A convergent plate boundary is where two tectonic plates move towards each other, often causing one plate to be forced beneath another.

Front

What is the primary characteristic of a divergent plate boundary?

Back

A divergent plate boundary is where two tectonic plates move away from each other, leading to the formation of new crust.

Front

What is the role of the lithosphere in Earth's structure?

Back

The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper mantle.

Front

What is the significance of fossils in geology?

Back

Fossils are used to correlate rock layers and provide information about the Earth's history and past life forms.

Front

What is the difference between a high silica and low silica volcano?

Back

High silica volcanoes tend to have explosive eruptions, while low silica volcanoes typically have quiet eruptions.
