What is Geology?

• the study of relationships between living things and their environment

• the study of the makeup of the earth and the processes that change and shape it

• . the study of the characteristics of the earth’s surface

• the study of past human life and activities by examining bones, tools, and other objects left behind

The theory of plate tectonics states that _________.

• Earth’s continents were once all joined together as one supercontinent

• Earth’s continents stay still and do not move

• Earth’s crust, mantle, and core all form tectonic plates that change very slowly

• Earth’s crust and part of the mantle are broken up into sections that slowly move

A process that moves sedmients to new locations

• Erosion

• Physical weathering

• Chemical Weathering

• Chemical and Physical weathering

What is a tsunami?

• A deep-sea geyser that forms as seawater sinks down through cracks in the oceanic crust and then releases extremely hot, mineral-rich water back up through cracks in the crust.

• An underwater volcano that forms wherever magma is erupting through oceanic crust

• a gigantic wave of seawater caused by an earthquake in oceanic crust.

What is a hydrothermal vent?

• A deep-sea geyser that forms as seawater sinks down through cracks in the oceanic crust and then releases extremely hot, mineral-rich water back up through cracks in the crust.

• An underwater volcano that forms wherever magma is erupting through oceanic crust

• a gigantic wave of seawater caused by an earthquake in oceanic crust.

What is a seamount?

• A deep-sea geyser that forms as seawater sinks down through cracks in the oceanic crust and then releases extremely hot, mineral-rich water back up through cracks in the crust.
