Q

How do the sun and earth’s shapes affect earth’s climate?

A

The suns energy is absorbed by things such as the land, oceans, and clouds. It is also reflected from clouds and other surfaces. The amount reflected depends on the ALBEDO of the material

Q

How does the atmosphere affect the climate?

A

The greenhouse effect helps keep the earth warm enough. Convection currents and wind help distribute that heat.

Q

How does the hydrosphere affect the climate?

A

Oceans act as heat sinks and help buffer heat on land. Warm ocean currents cream warn wet climates and cols currents create dryer climates

Q

What is transpiration?

A

Evaporation of water out of plants

19
Q

How does the atmosphere affect the weather?

A

Weather occurs in the troposphere

20
Q

What does falling air pressure mean?

A

Stormy weather coming

21
Q

What does rising air pressure mean?

A

fair weather coming

22
Q

What does steady air pressure mean?

A

no weather coming

23
Q

How does the ocean affect weather?

A

ocean currents affect the temperature of the land they pass by

24
Q

What is the evidence behind climate change?

A

Increase in global average temperature and higher greenhouse gas levels

25
Q

How do heat waves affect us?

A

increased use of power leads to more greenhouse gasses being produced, soil and lakes warm up, permafrost is melting much more

26
Q

How do wildfires affect us?

A

when the weather is dry, trees become so dry that the probability of wildfires

27
Q

How do storms affect us?

A

Rapid increase in the earths temperature can lead to more frequent and severe storms

28
Q

Describe how floods affect us

A

When air temperature warms quickly, snow can melt too quickly for rivers to handle

29
Q

How does melting ice affect us?

A

changing coastlines and shape of continental coasts, causes loss of property, flooding land, reduces amount of fresh water

30
Q

How does ocean warming affect us?

A

warm water expands, making sea levels higher, warm water is a less effective carbon sink, produces more hurricanes, kills phytoplankton

31
Q

What do thick tree rings mean?

A

the tree grew in better conditions

32
Q

What do thin rings on a tree mean?

A

the tree lived through poorer conditions

33
Q

Why do scientists look at tree rings?

A

To determine the weather conditions over the life of the tree

34
Q

What is another way scientists can find data about carbon in the past?

A

samples of the continental glacier

35
Q

When did CO2 levels begin to rise?

A

Around 1750 (industrial revolution)

36
Q

What is the anthropogenic greenhouse effect?

A

The enhancement of the natural greenhouse effect due to human activities

37
Q

What is a negative feedback loop?

A

A feedback loop that reduces the effect and helps maintain balance

38
Q

What is a positive feedback loop?

A

a feedback loop that increases the effect and produces instability

39
Q

Hoe does the greenhouse effect work?

A

Solar energy passes through the atmosphere, earth’s surface converts it to thermal energy, warms earth’s surface, infrared radiation is sent back to the atmosphere, its trapped by the atmosphere

40
Q

What is a greenhouse gas?

A

Any gas that absorbs infrared radiation

41
Q

What are some greenhouse gases?

A

Water vapor, carbon dioxide, methane and surface level ozone

42
Q

How does water vapor influence global warming?

A

Water vapor traps energy, making the earth warmer

43
Q

Why is methane a more potent gas?

A

Methane absorbs 23 absorbs more thermal energy than carbon dioxide
