Plate Tectonics

Difference in density between oceanic crust and continental crust and why that's important.

The oceanic crust is denser than the continental crust. This is important because this tells us what plate will be subducting.

Convergent plate boundary between oceanic-continental crust and the geologic outcomes for this type of convergence. Know real life examples of this type of plate boundary i.e.- Andes mountain range and Cascade mountain range.

Earthquakes- Valdivia Earthquake

Convergent plate boundary between continental-continental crust and the geologic outcomes associated with this type of plate boundary. Know real life examples of this type of plate boundary i.e.-The Himalayan mountain range.

Where do mid-ocean ridges and rift valleys form? How are they similar and how are they different?

Mid- ocean ridges form on divergent plate boundaries and rift valleys form on divergent boundaries too. They both form when the land moves away from each other. They are different because rift valleys form on land only and mid-ocean ridges form in the water only.

Subduction zone- What are they, what do they create, and where do you find them?

Subduction Zones are created when two tectonic plates meet. They can create earthquakes, volcanic eruptions, and tsunamis. They will form on a convergent boundary.

Convergent boundary between oceanic-oceanic crust and geologic outcomes associated with this type of plate boundary. Know real life examples of this type of plate boundary i.e.-The Aleutian Volcanic Island Arc.

San Andreas fault - What is it? What's happening here?

The San Andreas fault formed from two tectonic plates sliding past each other. Earthquakes occur along that fault line.

Convection currents-what are they responsible for, how do they work, and what do they cause?

They are responsible for plate tectonics movement. As the heat rises from the currents, it pulls down the colder fluid. As it goes down it gets heated up, it is a cycle. They cause volcanoes, earthquakes, and continental drift.

How do volcanoes form?

Volcanoes are formed when magma from within the Earth's upper mantle works its way to the surface. At the surface, it erupts to form lava flows and ash deposits. Over time as the volcano continues to erupt, it will get bigger and bigger.
