Rocks lock in their magnetism when they cool.

What do geologists think happened during the last ice age

Sea levels dropped 300 feet.

A land bridge connected Siberia and Alaska

What happened at the end of the Mesozoic era but did not happen at the end of the Paleozoic era

At which location is dynamic metamorphism most likely to occur

Transform boundary

Which type of power production produces the least amount of greenhouse gases

How long would it take a radioactive element with a mass of 20 grams to decrease to 5 grams if the half life is 1000 years

You would have to wait 2,000 years for this to occur.

Half of 2,000 is 1,000.

Half of 1,000 is 500.

This process happens twice. 1,000 years * 2 processes = 2,000 years.

What happens at a convergent boundary
