Unit Test 2

Question 1

Tsunami

Answer 1

a set of large ocean waves caused by an earthquake or another powerful disturbance under the sea

Question 2

Plate tectonics

Answer 2

the theory that Earths outer shell is made up of individual plates that move, causing earthquakes, volcanoes, mountains and the formation and destruction of areas of the crust

Question 3

Mid-ocean ridge

Answer 3

feature created by the spreading of the sea floor where two plates are diverging.

Question 4

Subduction

Answer 4

the process in which one plate slides underneath another, the subducted plate moves into earth’s interior and melts

Question 5

Divergent

Answer 5

occurs when two plates move apart

Question 6

Convergent

Answer 6

occurs when two plates move towards each other

Question 7

Erosion-

Answer 7

The movement of broken up pieces of rock

Question 8

Deposition

Answer 8

the building up of eroded materials in a new location

Question 9

Glaciation

Answer 9

the process of ice advancing and covering large areas of land

Question 10

Canadian Shield

Answer 10

an immense area of ancient worn-down mountains

Question 11

Lowlands

Answer 11

areas that surrounded the shield

Question 12

Highlands

Answer 12

areas the surrounded the lowlands

Question 13

Igneous rock

Answer 13

forms when magma or lava cools

Question 14

Sedimentary rock

Answer 14

created after millions of years of compaction and cementation of loose settlement

Question 15

Metamorphic rock

Answer 15

changed versions of igneous, sedimentary and other metamorphic rocks

Question 16

Rock cycle

Answer 16

IGNEOUS ROCK- FORMS WHEN MAGMA OR LAVA COOLS, MOST COOLING HAPPENS OUT OF SIGHT AND YOU CAN TELL HOW IT COOLS BY ITS CRYSTALS

WEATHERING, EROSION AND DEPOSITION- RELATED PROCESS THAT BREAKS DOWN ALL TYPES OF ROCKS INTO SMALL PARTICLES AND MOVE THEM TO A NEW LOCATION

SEDIMENTARY ROCK- CREATED AFTER MILLIONS OF YEARS OF COMPACTION AND CEMENTATION OF LOOSE SETTLEMENT

METAMORPHIC ROCK-CHANGED VERSIONS OF IGNEOUS, SEDIMENTARY AND OTHER METAMORPHIC ROCKS.

Question 17

glaciation

Answer 17

the process of ice advancing and covering large areas of land.

Question 18

Deposition by ice

Answer 18

MATERIALS DEPOSITED DIRECTLY BY ICE ARE NOT SORTED BY SIZE, THIS IS CALLED TILL COMMON FEATURE FORMED BY DEPOSITION ARE TILL PLAINS A COMMON FEATURE FORMED BY ICE IS A MORAINE

Question 19

Till plains ( deposition by ice)

Answer 19

SMALL FEATURELESS HILLS AND VALLEYS FORMED FROM ROCK
RELEASED BY GLACIERS

Question 20

Moraine

Answer 20

DEPOSITS OF TILL THAT FORM AT THE EDGE OF GLACIERS

Question 21

Deposition by water

Answer 21

MELTWATER MOVES GLACLAL DEBRIS. THE RESULT IS WE SEE MATERIALS SORTED BY SIZE MELTWATER RIVERS FLOW INTO MELTWATER LAKES, THERE IS VERY LITTLE MOVEMENT OF WATER HE LIGHTEST material LIKE SILT AND CLAY ARE DEPOSITED

Question 22

Answer 22

• Canadian Shield
• highlands
• lowlands

Question 23

Answer 24

Divergent
Convergent
Subduction
Transform

Question 25

Weathering

Answer 25

the breaking down of rocks
