Lesson 3

Question 1

Erosion

GIVE AN EXAMPLE :

Answer 1

Process when sediment is moved to a new place

GIVE EXAMPLE OF SOIL,ROCK AND SEDIMENT MOVING?

Question 2

Deposition

Answer 2

Process when eroded material is dropped

Question 3

Floodplain

Answer 3

Layers of sediment deposited after a flood

Question 4

Delta

Answer 4

Area where streams deposit their load - around the mouth

near the ocean???river enters ocean???

Question 5

Alluvial fan

WHY /HOW AND WHERE DO THEY HAPPEN?

Answer 5

Fan-shaped deposit that forms on dry land

forms where a stream gets to a flat aarea of land-slows- and puts sediments in that spot

Question 6

Groundwater

Answer 6

Water located within the rocks below earths surface

Question 7

Shoreline

Answer 7

Place where land meets water

Question 8

Headland

Answer 8

Finger shaped projections that form when cliffs of hard rock erode more slowly than surrounding rocks

Question 9

Sea cave

Answer 9

A cave formed when waves repeatedly hits the shoreline

Question 10

Sea arch

Answer 15

Long narrow island parallel to the beach

Question 16

HOw do Canyons an valleys form? Such as the Grand Canyon?

Answer 16

Rivers carving through mountains year after year

Question 17

Gradient?

Answer 17

The steepness of a river

Question 18

Question 19

Discharge?

Answer 19

B

Question 20

what would make more erosion happen?

Answer 20

Faster rivers

Question 21

Define and describe the processes of erosion and deposition?

Answer 21

Water picks up sediment and sets it down later or deposits it

Question 22

how does gravity, gradient and discharge and load relate to stream erosion and deposition?

Answer 22

ddd

Question 23

DESCRIBE WHAT HAPPENS TO SEDIMENT AS A STREAM SLOWS?

Answer 23

The heavier sediment begins to get deposited

Question 24

DESCRIBE THE ROLE OF STREAM EROSION AND DEPOSITION IN BUILDING LANDFORMS?

Answer 24

They move sediment to create landforms

Question 25

DESCRIBE THE EFFECTS OF EROSION BY GROUND WATER

Answer 25

Erosion by ground water can cause sinkholes

Question 26

DESCRIBE HOW EROSION AND DEPOSITION BY WAVES AND CURRENTS SHAPE SHORELINES??

Answer 26

They hit the shoreline at different angles causes it to change

Question 27

Explain how water deposits soil, sediment and rock. Give 2 examples

Answer 27

When the stream slows down till it doesn't have the power to move a rock Delta Alluvial fan

Question 28

What would you see on the beach if it had been affected by stormy seas and rough waves?

Answer 28

You would see less sand

Question 29

Can water move a 5lb rock

Answer 29

Yes

Question 30

What can deposition make

Answer 30

Landforms
