Topic 2-Fresh & Salt Water Systems

Question 1

Waves

Answer 1

A circular motion of water particles which causes a change in pattern that moves along the waters surface.

Question 2

Tide

Answer 2

Daily change in water level of the oceans.

Question 3

Stream Characteristics

Answer 3

Characteristics used to describe a stream

Question 4

Sediments

Answer 4

Eroded rock fragments and soil carried by wind or water

Question 5

Continental Divide

Answer 5

Highest point of land on a continent. Rivers flow into different oceans depending on which side of the divide they start.

Question 6

Glaciers

Answer 6

A large moving body of ice

Question 7

Climate

Answer 7

Average weather over a long period of time.

Question 8

Currents

Answer 8

A stream of water that moves within a larger body of water

Question 9

Water Shed

Answer 9

All the area of land that drains into one main lake

Question 10

Describe the Stream Characteristic:

Glacier

Answer 10

A river or stream may start in the mountains where a glacier is melting. This is its source.

Question 11

Describe the Stream Characteristic:

Stream

Answer 11

The water from the streams source collects into a channel that forms a small stream. The volume of the stream increases as other streams flow into it.

Question 12

Describe the Stream Characteristic:

High Flow

Answer 12

In the rivers early sage, it flows swiftly and quickly

Question 13

Describe the Stream Characteristic:

Meander

Answer 13

Soon the river reaches lower elevations, and the ground becomes more level. The river flows more slowly here. This causes it to move in large curves.

Question 14

Describe the Stream Characteristic:

Flood Plain

Answer 14

The flat land on either side of the river becomes covered in water whenever the river overflows its banks.

Question 15

Describe the Stream Characteristic:

Low Flow

Answer 15

At it’s mouth the river enters a lake or ocean. The flow of the water slows down much more.

Question 16

Describe the Stream Characteristic:

Delta

Answer 16

When the river flows into a lake or ocean, it drops much of the sediment its carrying. This sediment forms a fan shaped deposit.

Question 17

Describe the Glacier landform:

Moraines

Answer 17

Moraines form from rock and gravel that build up along the sides and at the end of the glacier. As the edges of the glacier melt, large deposits form.

Question 18

Describe the Glacier landform:

Eskers

Answer 18

Eskers form when parts of the glacier melt. This melt water flows in tunnels under the ice. The melting releases sand and gravel from the glacier.

Question 19

Describe the Glacier landform:

Drumlins

Answer 19

Drumlins are small hills with a distinctive tear-drop shape. They form when a glacier moves over moraines that formed earlier.

Question 20

Describe the Glacier landform:

Kettle Lake

Answer 20

This type of lake forms when large chunks of ice left by the glacier melt.
