Digital Lesson 7.3

Question 1

Weathering

Answer 1

When wind, rain, and temperature changes beak down rock

Question 2

Chemicals weathering

Answer 2

The chemical breakdown of rocks

Question 3

Physical weathering

Answer 3

The mechanical breakdown of rock into smaller pieces, caused by natural processes

Question 4

Erosion

Answer 4

The process by which wind, water, ice, or gravity transports soil and sediment from one location to another

Question 5

Deposition

Answer 5

The process in which material is laid down

Question 6

When water freezes, it

Answer 6

Expands and thaws to break rocks

Question 7

What type of physical weathering is caused by the repeated freezing and thawing of ice

Answer 7

Frost wedging or ice wedging

Question 8

Exfoliation

Answer 8

When rock splits and breaks off in sheet layers, similar to onion layers

Question 9

Difference between mass movement and creep erosions

Answer 9

Mass movements happen quickly and creep erosions happen slowly

Question 10

Moving water can form what

Answer 10

Valleys and canyons

Question 11

How do alpine glaciers cause erosion

Answer 11

As these huge masses of ice grow,

They slowly advance down valleys and scrape pieces of land

Question 12

What features are formed by alpine glacial erosion

Answer 12

U shaped valleys

Question 13

What is a wave cut platform

Answer 13

Form when a cliff collapses

Question 14

How is a sea arch formed

Answer 14

It forms when 2 caves form back to back and water continuously hits them,
The rock between the caves is eroded, forming a sea arch

Question 15

Delta

Answer 15

Coastal deposits shaped like triangles. Form when River enters another body of water

Question 16

Barrier islands

Answer 16

Large mounds of sediment dropped parrallel to the shore

Question 17

Sand spits

Answer 17

When waves and currents deposit sand perpendicular to the shore, sandspits form. Sandspit form just out of the beach or the mainland

Question 18

Alluvial Fan

Answer 18

Triangular deposit formed on land

Question 19

Till

Answer 19

Sediment dropped off by a glacier

Question 20

What is continental glacier called

Answer 20

Glacial erratic

Question 21

What is the drumlin and how can it be used

Answer 21

Deposit form when a massive ice sheet or continental glacier covers the land. Long narrow hills of sediment are left behind

Question 22

Outwash

Answer 22

The sediment deposited by glacial meltwater

Question 23

Land features formed by weathering

Answer 23

Oxidation rocks, exfoliation dome

Question 24

Land features formed by erosion

Answer 24

Rockfall, Valley

Question 25

Land features formed by deposition

Answer 25

Delta, drumlin

Question 26

Difference between stalactites and stalagmites

Answer 26

Stalactites are rock “icicles” that hang from cave ceilings. Stalagmites are rock pinnacles that seem to grow upward from the cave floor
