plate tectonics

Question 1

The outermost shell of a rocky planet.

Answer 1

Crust

Question 2

Layer of molten rock between the crust and core

Answer 2

mantle

Question 3

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

Answer 3

Core

Question 4

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

Answer 4

Tectonic Plate

Question 5

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

Answer 5

Asthenosphere

Question 6

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

Answer 6

Convection Current

Question 7

When two tectonic plates come together

Answer 7

Convergent Boundary

Question 8

Uplift of crustal plates that form elevated landmasses.

Answer 8

Mountains

Question 9

A vent or fissure in Earth’s surface through which magma and gases are expelled.

Answer 9

Volcanoes

Question 10

When tectonic plates slide past each other.

Answer 10

Transform Boundary

Question 11

Breaks in the crust. The movement causes seismic waves which produces earthquakes.

Answer 11

Fault

Question 12

A long ridge of underwater volcanoes between two diverging oceanic plates

Answer 12

Mid-Ocean Ridge

Question 13

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

Answer 13

Subduction Zone

Question 14

A long narrow valley between two diverging continental plates

Answer 14

Rift Valley
