Atmosphere & Storm weather event

Question 1

Water cycle

Answer 1

Movement of water around
1. Evaporation
2. Condensation
3. Precipitation
4. Surface water
5. Ground water

Question 2

Three types of rain

Answer 2

Relief rain: orogrophic
- occurs when a moist air mass is forced to rise over a mountain.

Convectional rain
- occurs when warm, moist air rises rapidly from the Earth surface.

Frontall rain: cyclonic
- occurs when 2 different air masses meet.

Question 3

Three types of clouds

Answer 3

Cumulus clouds - the puffy clouds that look like puffs of cotton.

Stratus clouds - look like flat sheets of clouds.

Cirrus clouds - high feathery clouds.

Question 4

Greenhouse effect

Answer 4

The greenhouse effect is a natural process that helps to keep the Earth warm. Certain gases in the Earth’s atmosphere, like carbon dioxide and methane, act like a blanket, trapping heat from the sun and preventing it from escaping back into space. This trapped heat keeps the planet at a livable temperature for plants, animals, and humans. However, human activities are increasing the levels of these gases, leading to an enhanced greenhouse effect and causing global warming.

Question 5

Cold/warm fronts

Answer 5

-◠-◠-◠-◠- warm front
△△△ cold front
△◠△◠△◠ occlusion - happens when a warm catches up on cold front (nice weather)

Question 6

Front is

Answer 6

the boundary between the warm air and the cold air.

Question 7

Weather event you have studied

Answer 7

Storms
- usually caused by the interaction of different air masses with varying temperatures and moisture content.
- as these air masses collide, they create instability in the atmosphere, leading to the formation of clouds and the release of energy in the form of storms.

Question 8

Weather instruments

Answer 8

• anenometer
• wind vane
• stevenson screen
• barometer
• maximum and minimum thermometer
• combell-stokes sunshine recorder
• rain gauge
• wet and dry belb thermometer/hydrometer
