Weather And Climate

Question 1

Weather

Answer 1

Atmospheric conditions (temperature, precipitation, wind, humidity etc.) in a particular location over a short period of time.

Question 2

Climate

Answer 2

Usual pattern of weather over a long period of time. Using climate data you can get expected weather.

Question 3

Temperature

Answer 3

The degree or intensity of heat present in a substance or an object.

Question 4

Ozone

Answer 4

It’s O3. It has a sharp, strong order. It is highly reactive.

Two kinds of ozone’s:
1. Good ozone, it prevents most of the dangerous UV rays from the sun. It’s in the stratosphere.

2. Bad ozone. This is in the troposphere (where we live). It has toxic effects. Bad ozone is a major contributor to smog and air pollution.

Question 5

Altitude

Answer 5

The height of an object or point in relation to sea level or ground level.

Question 6

Latitude

Answer 6

The angular distance of a place north or south of the earth’s equator, usually expressed in degrees and minutes.

Question 7

Fossil Fuels

Answer 7

A natural fuel, like coal, formed in the geological past from the remains of living organisms.

Question 8

Anthropogenic CO2

Answer 8

The amount of CO2 caused by humans.

Question 8

Carbon “sink”

Answer 8

Forest, ocean, or other natural environments viewed in terms of its ability to absorb carbon dioxide from the atmosphere.

Question 9

CO2

Answer 9

Can stay in the atmosphere for 100’s of years (reservoir). Plants take the carbon out of the atmosphere.

Question 10

Carbon “footprint”

Answer 10

The amount of carbon dioxide and other carbon compounds emitted due to the consumption of fossil fuels by a particular person, group, etc.

Question 11

Nitrous Oxide (NO2)

Answer 11

A colourless gas with a sweetish oder, prepared by hearting ammonium nitrate. It can be an aerosol propellant.

Question 13

Methane (CH4)

Answer 13

Methane is a chemical compound with the chemical formula CH4, is the main constituent of natural gas.

Question 14

Proxy Records

Answer 14

Records that are indirectly inferred, rather than actually measured.

Question 19

Effects of Climate Change

Answer 19

1. Loss of sea ice (glaciers etc.)
2. Accelerated sea level rise.
3. More intense heat waves.
4. Forest fires.
5. Threatens health through increased diseases, freshwater shortages, and increased smog.

Question 20

Mountain Pine Beetle

Answer 20

Is a species of bark beetle native to the forests of western North America from Mexico to central British Columbia.

Question 21

Chlorofluorocarbons

Answer 21

Any of the simple gas compounds that contain carbon, chlorine, fluorine, and sometimes hydrogen, that are used as refrigerants, cleaning solvents, and aerosol propellants. Are believed to be a major cause of stratospheric ozone depletion.

Question 22

Ice Core

Answer 22

Is a core sample that is typically removed from an ice sheet or a high mountain glacier. They can reach depths of over two miles (3.2 km), and contain ice up to 800,000 years old.

Question 23

Feedback Loop

Answer 23

In a climate change, a feedback loop is the equivalent of a vicious or virtuous circle. Something that accelerates or decelerates a warming trend.

Positive feedback loop:
Accelerates temperature rise.

Negative feedback loop:
Decelerates temperature rise.

Question 24

Greenhouse Gas Effect

Answer 24

The atmosphere of a plant traps radiation emitted by it’s sun, caused by gases such as carbon dioxide, water vapour, and methane. The heat is radiated back from the plants surface.

Question 26

Thermal Expansion of Water

Answer 26

The tendency of matter to change in shape area and volume in response to temperature change in climate.

Question 27

Greenhouse Gases

Answer 27

A gas that Contributes to the greenhouse effect by absorbing infrared radiation.
