Question 26

combining is

Answer 26

aggregation

Question 27

those rock particles get carried away by wind, water, ice and gravity

Answer 27

Erosion

Question 28

agents of erosion

Answer 28

• Water • Wind • Ice • Gravity

Question 29

changes the shape of coastlines. Waves constantly crash against shores. They pound rocks into pebbles and reduce pebbles to sand. It sometimes takes sand away from beaches. This moves the coastline farther inland.

Answer 29

erosion by water

Question 30

carries dust, sand, and volcanic ash from one place to another. Wind can sometimes blow sand into towering dunes.

Answer 30

Erosion by wind

Question 31

can erode the land. In frigid areas and on some mountaintops, glaciers move slowly downhill and across the land. As they move, they pick up everything in their path, from tiny grains of sand to huge boulders.

Answer 31

Erosion by ice

Question 32

it pulls any loose bits down the side of a hill or mountain. it is better known as Mass Movement.

Answer 32

Gravity Erosion

When weathered rock remains in place and remains in its pure state.

Answer 33

REGOLITH

Question 34

When weathered material is removed from the site of weathering

Answer 34

SEDIMENT

Question 35

It is the main agent of erosion

Answer 35

MOVING WATER

Question 36

Nowadays, people became one of the causes of erosion.

Answer 36

PEOPLE

Question 37

Weathered rock material will be removed from its original site and transported away by a natural agent.

Answer 37

WEATHERING AND EROSION

Question 38

rubble, trash, random material like large pieces of wood, metal or plastic

Answer 38

debris

Question 39

river of flowing mud

Answer 39

slurry

Question 40

an incline,like a slide or ramp

Answer 40

slope

Question 41

land that is close to a coast or near water or sea levels

Answer 41

low-lying area

Question 42

It is a natural process in which a material is carried to the bottom of bodies of water and forms to solid.

Answer 42

SEDIMENTATION

Question 43

is the movement of rock, soil and regolith downward due to the action of gravity

Answer 43

Mass wasting

Question 44

triggered by the following factors:
