Front

What is half-life?

Back

Half-life is the time required for half of the atoms in a radioactive isotope to decay.

Front

How do you sequence rock layers from oldest to youngest?

Back

To sequence rock layers from oldest to youngest, you can use the principle of superposition, where the oldest layers are at the bottom.

Back

The Hawaiian Islands were created by hot spot volcanoes.

Front

What is weathering?

Back

Weathering is the process of breaking down rocks and minerals into smaller pieces through natural processes.

Front

What is the difference between relative age and absolute age?

Back

Relative age is the age of a rock layer compared to other layers, while absolute age is the actual age of a rock or fossil.

Front

What is exfoliation in geology?

Back

Exfoliation is the process where layers of rock peel away due to temperature changes and pressure release.

Front

What are divergent boundaries?

Back

Divergent boundaries are tectonic plate boundaries where two plates move away from each other, often creating new crust.
