What is a transform boundary?

Back

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

Front

What is an isotope?

Back

An isotope is an atom of the same element that has a different number of neutrons, resulting in a different mass.

Front

What is the average mass of beanium if the data shows 0.218?

Back

0.218

Front

What causes earthquakes in California and Japan?

Back

Both areas are on the boundary of active plates, and the motion of the plates causes earthquakes.

Front

What is a convergent boundary?

Back

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

Front

What is a divergent boundary?

Back

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

Front

What is a nucleus?

Back

The nucleus is the central part of an atom, containing protons and neutrons.

Front

What is an atom?
