A

The ice age was a time when the Earth was colder and a lot of the planet was covered in ice.

48
Q

What causes changes in climate?

A

A change in climate is caused by changes in Earth’s energy balance. The earth’s climate will change if something causes the earth’s surface and atmosphere to absorb the sun’s energy in a different way or a different amount of energy is received from the sun. This causes the climate to change.

A

A time between ice ages when Earth warms up.

56
Q

What is the role of the atmosphere?

A
  • Tropical
  • Dry
  • Moderate
  • Polar
  • Continental
61
Q

How do ocean curents affect Earth’s climate?

A

Ocean curents act as a conveyor belt, they transport warm and cold water around the earth to regulate climate.

62
Q

Define mitigation

A

Reducing an unwanted change by deliberate decisions and actions

63
Q

Why can’t we convert fully to clean energy?

A

We can’t fully convert to clean energy because not everyone has the resources to swich to cleaner alternatives. For hydro electricity, you must live near a big body of moving water to generate it. There can not be wind turbines in cities and solar panels are very expensive.

64
Q

Name a long and short term change in climate and how the change affects the climate.

A

Long: Movement in Earth’s crust:

When the Earth’s crust moves or changes, it affects how the Earth absorbes energy from the sun which would affect climate.

Short: Volcanic eruptions:

Volcanic eruptions cause sulfer-dioxide to be egected into the atmosphere. Sulfer-dioxide reflects the sun’s rays causing Earth to cool down.

There are other answers,

Cyclic changes, changes in the circulation of Ocean curents, ect.

65
Q

What are the 5 main climate zones?

A

Tropical, Dry, Polar, Continental, Moderate

66
Q

What are the 3 Methods in which energy can be transferred from one place to another?

A

Conduction, Convection, Radiation.

67
Q

What are some signs that climate change is real?

A

Rising temperatures, melting glaciers, rising sea level, changes in severe weather, changes in ecosystems, changes in precipitation patterns.

68
Q

how can climate change affect human health?

A

As tropical weather spreads to higher latitudes, tropical diseases could come with them, air pollution caused by the burning of fossil fuels could lead to higher rates of asthma and heart disease.

69
Q

Which component of Earth consists of living things?

A

Biosphere

70
Q

What makes clean energy better than non-renewable energy?

A

Clean energy has much less effects on the environment than non renewable energy. Non renewable energy requires unsustainable practices and methods used to extract the materials used. Clean energy uses natural occurring movement and actions to produce energy. Most importantly they don’t release massive amounts of greenhouse gas into the atmosphere.

71
Q

List and describe the 4 components of earth’s climate system

A

Atmosphere: Made of layers of gases surrounding the earth
Hydrosphere: Includes water in oceans and lakes, water vapor in the earth’s atmosphere, ice in glaciers and poles
Lithosphere: earth’s rock crust, including land surfaces
Living things: everything that’s living on earth

72
Q

List 2 practices/actions that contribute to methane emissions.

A

Agricultural Activities: Rice farming, and Cattle farming
Decay of Organic materials: Landfills, sewage treatment plants
Coal mining
Natural gas extraction

73
Q

Why is the north and south pole colder than the equator?

A

The sun’s energy hits the equator directly, however it hits the north and south poles on an angle and spreads over a large surface area.

74
Q

Why is rising sea levels an issue?

A

Coastal areas that are mostly unelevated will have increased risk of flooding, and some will end up below sea levels: such as Florida .

75
Q

Explain climate projection

A

A climate projection is a scientific forecast for future climate based on observations and computer models.

open-ended question, might have different answers

78
Q

Name and explain 2 of the ways that climate change in the Arctic will impact the world.

A

Sea levels: More water flows into oceans when ice melts, causing the sea level to rise.
Permafrost: Permafrost contains stored carbon dioxide and methane (more than what is in the atmosphere today). If it melts, these gases are released, enhancing the greenhouse effect.
Biodiversity: Some migratory species have breeding grounds in the Arctic. If the ecosystem changes, it will affect species all around the world.
