Geography - Weather Elements/ Hydrological Cycle/ Types of Rainfall

Question 1

Define weather

Answer 1

The state of atmosphere at a particular place and time regarding cloudiness, heat, dryness, sunshine, wind etc
Made up of all wether elements; temperature, wind, visibility, precipitation

Question 2

Define climate

Answer 2

The usual weather conditions that have been in a certain place for a long period of time

Question 3

Difference weather and climate

Answer 3

Weather- temperature conditions that temporarily arrive
Climate- temperature/weather conditions that are usually found in that certain place or have been there for a long period of time

Question 4

List all the weather element

Answer 4

Temperature
Wind
Visibility
Precipitation 
Air temperature

Question 5

Define all weather elements

Answer 5

Temperature- heat or coldness that can be measured using a thermometer
Wind- is air that is moving and is measured using an anemometer; produced by uneven heating of the earths surface by the sun
Air temperature- temperature of the air affects growth and reproduction of plants and animals
Visibility- how well you can see determined by the weather: poor visibility is caused usually by fog
Precipitation- any form of water falling from the atmosphere onto earths surface. I.e rain,snow, hail

Question 6

Impacts of weather

Answer 6

High tides - large waves heading for shore, creating floods
Powerful winds- destroy streets and mess up forests/shops
Chilly temperature- breedings of lamb in some places may not take place as well as if it was warmer, lambs might not survive the harsh weather
Too Hot temperatures/ little rain- dry out crops, water sources evaporate,
Clear skies, warm weather, low levels of precipitation- great for tourism
Snow storms- limits mobility in those areas, create destruction
Icy roads, poor visibility - fatal accidents on roads

Question 7

Define hydrological cycle

Answer 7

The process by which water is circulated throughout the earth and the atmosphere

Question 8

How is evaporation used in the hydrological cycle

Answer 8

The sun produces energy down to earth

Surfaces heat up and the liquid water evaporates and turns into a gas

Question 9

How does condensation come into the water cycle

Answer 9

The water vapour particles rise into the earths atmosphere and cool
They turn back from a gas into a liquid
Forms a cloud filled with other water molecules

Question 10

Another word for condensed water

Answer 10

Clouds

Question 11

Another word for hydrological cycle

Answer 11

Water cycle

Question 12

How do the clouds travel

Answer 12

The pushes them around the earths atmosphere

Along the way the amount of water droplets in the cloud increase

Question 13

How does the water droplets fall

What is this called

Answer 13

When many have stuck together they start to fall

This is precipitation

Question 14

Define precipitation

Answer 14

Water released from clouds in the form of rain, freezing rain, sleet, snow, hail

Question 15

How do the water droplets change matter

Answer 15

If they are cold enough they can turn into ice crystals, snow

Question 16

Define surface runoff

Answer 16

This is when the precipitation falls and flows over the ground
This water is either quickly evaporated again or flows into channels/lakes/seas

Question 17

Define infiltration/ throughflow

Answer 17

Process by which water on the grounds surface sinks into ten soil and is either stored their or finds it way back to a water source
This process typically takes longer than surface runoff

Question 18

Define relief rainfall

Answer 18

• warm air rises due to heat from the sun, forced over mountains
• condenses into water droplets forming clouds
• wind pushes those clouds over the mountains
• clouds become heavy and produces a form of precipitation
• precipitation falls on opposite side of mountain

Question 19

Define convectional rainfall

Answer 19

• sun heats up equator
• water evaporates in a form of water vapour, begins to rise
• as it travels further up it will condense
• clouds will eventually release water droplets as a form of precipitation

Question 20

Define frontal rainfall

Answer 20

• two air masses meet, warm + cold
• cold air, more dense and heavy, forces the warm air to rise
• this creates the front (boundary between two air masses
• warm air cools and form condensation, build clouds
• clouds become heavy and fall(precipitation)
