Tectonic Plates

Question 1

Faulting

Answer 1

When tension and compression associated with plate movement is so great that blocks of rock fracture or break apart

Question 2

Folding

Answer 2

Occurs where the crust is pushed up as plates collide which causes the crust to rise up in folds.

Question 3

Ocean Ridge

Answer 3

An elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crusts forms from upwelling magma.

Question 4

Ocean trench

Answer 4

Steep depressions in the deepest parts of the ocean and are the deepest regions on the earth.

Question 5

Subduction

Answer 5

Movement of the edge of one tectonic plate under another

Question 6

Tectonic

Answer 6

Pertaining to the structure or movement of earth’s crust

Question 7

Isotope

Answer 7

atom with the same atomic number, different number of neutrons

Question 8

Convection

Answer 8

The process where heat causes fluid (gas or liquid) to rise and bring up heat

Question 9

Fossil Fuel

Answer 9

An energy source (fuel or gas) made from ancient plant or animal remains

Question 10

Fossil Record

Answer 10

A piece of evidence for evolution that shows the development of organisms over time across the world

Question 11

Fossil

Answer 11

The remains or an impression of a plant or animal that existed in a past geological age

Question 12

Igneous

Answer 12

Rock that is formed from cooled magma or lava

Question 13

Lithosphere

Answer 13

The section of Earth that is composed of rock

Question 14

Magma

Answer 14

Melted rock inside of the the Earth

Question 15

Metamorphic

Answer 15

Rock formed when igneous or sedimentary rock is put under pressure, heated, or reacts chemically

Question 16

Plate Tectonics

Answer 16

The theory that the earth’s surface is divided into a few large, thick plates that are constantly moving

Question 17

Radiometric Dating

Answer 17

Determining the age of a rock or fossil based on amount of one isotope compared with another isotope.

Question 18

Sea-floor spreading

Answer 18

When oceanic plates move apart, the middle fills in with magma with cools and forms new sea floor

Question 19

Continental Drift

Answer 19

The theory that states the continents are constantly in motion

Question 20

Deep interior

Answer 20

The mantle and core of the earth

Question 21

Sedimentary Rock

Answer 21

Rocks formed by the accumulation of small particles-often mineral or organic particles on the floor of oceans or other bodies of water at the Earth’s surface
