Back 1

Divergent Boundaries

Hint 1

Move away from each other

Front 2

When 2 plates are pushed together

Back 2

Convergent Boundaries

Hint 2

Collide and crash into each other

Front 3

Occurs when 2 plates slide past each other

Back 3

Transform Boundary

Hint 3

Slide next to each other side by side

Front 4

A long time ago there was one giant continent

Back 4

Pangaea Supercontinent

Hint 4

Continents today fit together like a puzzle; same fossils found on different continents

Front 5

Earthquakes can form mountains and other landforms

Back 5

Constructive Earthquakes

Hint 5

Build up

Front 6

Earthquakes can destroy land and make buildings fall down; earthquakes can cause volcanoes to erupt and tsunamis to happen

Back 6

Destructive Earthquakes

Hint 6

Damage

Front 7

This is what happens when earth releases energy and causes plates to move

Back 7

Earthquakes

Front 8

Where earthquakes happen; breaks in the earth's crust

Back 8

Faults

Front 9

Measures magnitude (size) of earthquakes

Back 9

Richter Scale

Front 10

Enormous waves caused by underwater earthquakes

Back 10

Tsunami

Hint 10

Huge wave starts in ocean and can hit land and cause floods

Front 11

Slowly wearing away of rocks

Back 11

Weathering

Hint 11

Destructive process

Front 12

Loosening and moving particles and sediment of rock by wind, water or ice

Back 12

Erosion

Front 13

Materials and sediments added to landforms

Back 13

Deposition

Hint 13

Deposited

Front 14

Land at the end of river where sediments deposited

Back 14

Delta

Hint 14

Shaped like a fan

Front 15

Slow moving chunks of ice

Back 15

Glaciers

Front 16

Someone who studies earthquakes

Back 16

Seismologists

Hint 16

Locate areas that might shake so people can plan for safety or build safer buildings

Front 17

Destructive when eroding land; constructive when building up soil, good for certain plants that have adapted

Back 17

Flood

Hint 17

Mass amounts of water

Front 18

Stop flow of river to make lake

Back 18

Dam

Front 19

Wall of earth or concrete built along banks to hold back water

Back 19

Levee

Front 20

Most roads have these to prevent flooding

Back 20

Drains

Hint 20

Flood control

Front 21

Replacing erosion of beaches caused by waves pulling in and out

Back 21

Beach reclamation

Front 22

Wall like structure sticking out into ocean to save beaches from erosion

Back 22

Jetty

Front 23

Natural or artificial land mass that protects coast by blocking big waves

Back 23

Reefs

Front 24

Areas of earth 's surface where magma and gasses are released

Back 24

Volcano

Front 25

Hill of sand made by wind or water

Back 25

Sand Dune

Front 26
