Name the 3 types of heat transfer. Here are some hints…

Types of Heat Transfer:

What is the boundary called where 2 plates pull away from each other or divide?

Divergent Boundary

What is the boundary called where 2 plates crash or crunch into each other?

Convergent Boundary

The stress that presses rock at convergent boundaries is ____. A The stress that presses rock at convergent boundaries is ____. A. tension B. compression C. shearing

Compression

What are 2 geologic features that may occur at divergent boundaries?

Rift Valley: Seafloor Spreading creates new ocean floor:

True or False? Shearing is the stress that stretches rock thin at divergent boundaries.

FALSE! Tension stretches rock thin at divergent boundaries.

True or False? Shearing stresses rock so much that it breaks at strike slip faults?

TRUE!

What geologic event could occur at a transform boundary?

Earthquakes!

Geologists learn about the interior of Earth by studying ___. Land formations Seismic waves Weather patterns

Seismic Waves

What process is shown below?

Subduction zone: Where a dense plate dives under a less dense plate Subduction zone: Where a dense plate dives under a less dense plate. Rock can be “recycled” as it melts back into magma. Volcanoes may erupt here.

What causes the mantle rock to flow very slowly?

Convection Currents

Look at this diagram. I have some questions for you…
