Plate Tectonics

Question 1

Crust

Answer 1

The outermost shell of a rocky planet.

Question 2

Mantle

Answer 2

Layer of molten rock between the crust and core

Question 3

Core

Answer 3

Made up of mostly Iron. Separated into the outer core(molted) and inner (solid)

Question 4

Tectonic Plates

Answer 4

The layer of rock that up the outer and of the Earth, including the crust and upper mantle (lithosphere plates)

Question 5

Continental Drift Theory

Answer 5

He theory that continents gradually drift over tie to their present position

Question 6

Asthenosphere

Answer 6

A thin layer of Earth, About 150 miles thick, at the border between th mantle and the crust.

Question 7

Convection Current

Answer 7

The process in which the hotter parts of a gas or liquid rise o the top and the cooler, Denser parts sink.

Question 8

Convergent Boundary

Answer 8

When two tectonic plates come together.

Question 9

Mountains

Answer 9

Uplift of crustal plated hat form elevated landmasses

Question 10

Valcanoes

Answer 10

A vent fissure in Earths surfaces through which magma and gases are expelled

Question 11

Divergent Boundary

Answer 11

when tectonic plated split apart

Question 12

Transform Boundary

Answer 12

When tectonic plated slide past each other

Question 13

Fault

Answer 13

Breaks in the crust. The movement causes seismic wakes produces earthquakes

Question 14

Mid ocean ridge

Answer 14

A long ridge of underwater volcanoes between two diverging oceanic plates.

Question 15

Subduction Zone

Answer 15

A place where one tectonic plate sinks under another and melts. And forms a trench.

Question 16

Rift Valley

Answer 16

A long narrow valley between two diverging continental plates
