Carolyn's relatives live in Canada and the Northern part of the United States. Her uncle told her that the glaciers once covered both of these regions. what is the result of glaciers having once covered these regions?

• Heavy frost occurs year round.

• Temperatures always remain cold.

• New oceans and seas where formed

• Many lakes and streams were created

Which statement is best represented by this diagram?

• All carbon is in the form of carbon dioxide.

• Carbon can exist in many forms, but the total amount of carbon stays the same.

• The amount of carbon in the cycle can increase or decrease based on the number of factories.

• Only living things release carbon dioxide into the atmosphere.

The setup in the diagram is left outside during the day and at night. Bubbles are continuously produced regardless of the presence or absence of sunlight. What can you predict about the composition of the gas in the bubbles?

• The bubbles are always oxygen (O2)

• The bubbles are always carbon dioxide (CO2).

• During the day, the bubbles are CO2 and the bubbles are O2 at night.

• During the day, the bubbles are O2 and the bubbles are CO2 at night.

Why does the oceanic crust sink beneath the continental crust at a subduction boundary?

• The oceanic crust has a greater density.

• The oceanic crust is pulled downward by Earth’s magnetic field.

• The continental crust is composed of more magnesium and iron.

• The continental crust is pulled upward by the Moon’s gravity.

What is the most likely cause of the earthquakes near this plate boundary?

• A transform fault

• A mantle hot spot

• Subduction of a crustal plate
