In what way is a river valley like a canyon?

Both are formed by moving water

There is a group of boulders in a field that were once far away from the field. What moved these boulders to the field?

Erosion and deposition by a glacier

A farm near a river has very rich soil. What caused the soil to be so rich there?

Floods from the river deposited the rich soil

A sandstorm can move sand over great distances. What most likely happens during a sandstorm?

Sediment is deposited in a new place

The breaking apart or wearing away of rock

A house is on a low cliff near an ocean. Which of these describes how erosion could affect the house?

Sediment that the house is standing on could be removed

How is a delta formed?

A river deposits sediment when it reaches an ocean

How does weathering help form a sandy beach by the ocean?

Waves break rocks into pieces, making grains of sand

A rock has a small crack with water in it. After winter passed, the crack had changed. What happened to the crack?

It got bigger because the water froze and expanded

Long Island, New York was shaped by glaciers. Two moraines are found on Long Island. How did they form?

As the glaciers melted away, sediment was deposited

Which of these is an example of Earth's surface changing slowly over time?

Questions 15

Answers

1
In the desert, wind carrying sand causes abrasion to rocks. What will happen to the rocks over time?
They will crack
They will blow away
They will become bigger
They will become smoother
2
A deep cave was discovered underground. The walls were made of limestone. The cave formed through weathering by
Heavy Wind
Weak Acid
High Waves
Glacial ice
3
In what way is a river valley like a canyon?
Both are formed by moving water
Both are flat areas of land
Both rise high above the land around them
Both can be found near oceans
4
There is a group of boulders in a field that were once far away from the field. What moved these boulders to the field?
Weathering and abrasion by a sinkhole
Weathering and erosion by a river
Erosion and deposition by a glacier
Abrasion and deposition by a sandstorm
5
A farm near a river has very rich soil. What caused the soil to be so rich there?
Wind brought the rich soil from the river
Floods from the river deposited the rich soil
Plants cracked rocks into pieces to make the soil rich
Rain dissolved minerals to make the soil rich
6
A sandstorm can move sand over great distances. What most likely happens during a sandstorm?
Sediment is deposited in a new place
Water freezes and splits rocks
Rocks and soil slide down a hillside
A cave forms underground
7
Which landform is found only where land meets an ocean?
Plain
Valley
Mountain
Coastline
8
What is weathering?
The creation and destruction of landforms by weather
Movement of sediment from one place to another
Dropping of sediment in a new place
The breaking apart or wearing away of rock
9
How do weathering and erosion cause a landslide?
Moving ice deposits sediment
Weak acid dissolves limestone
Sandstorms blow sediment against rock
Rock and soil slip downhill
10
A house is on a low cliff near an ocean. Which of these describes how erosion could affect the house?
The soil around the house could be moved by a glacier
Sediment that the house is standing on could be removed
The paint on the house could be worn away by abrasion
Extra sediment could build up around the house
11
How is a delta formed?
Ocean waves carve out a delta with moving water
A river deposits sediment when it reaches an ocean
A river carves out a delta with rushing water
A glacier deposits sediment when it melts in an ocean
12
How does weathering help form a sandy beach by the ocean?
Chemicals in the waves dissolve large rocks into sand
Waves break rocks into pieces, making grains of sand
Sandstorms deposit sand from nearby deserts
Melting glaciers deposit grains of sand
13
A rock has a small crack with water in it. After winter passed, the crack had changed. What happened to the crack?
It got bigger because the water froze and expanded
It got smaller when the water mixed with dust
It got smaller after the water deposited sediment
It got bigger because the water eroded the rock
14
Long Island, New York was shaped by glaciers. Two moraines are found on Long Island. How did they form?
Rocks carried in the glaciers became sharp and jagged
As the glaciers melted away, sediment was deposited
The glaciers caused erosion, which enriched the soil
The ice in the glaciers caused rocks to freeze and break apart
15
Which of these is an example of Earth's surface changing slowly over time?
Valleys get a little narrower each year
Wind gets a little stronger each year
Canyons get a little deeper each year
Waves get a little bigger each year
