Climate Change

What does this graph represent?

• At sea level, air pressure is minimal

• As elevation decreases, air pressure increases

• At sea level, air pressure is at it's greatest

• More than one answer is correct.

Carbon dioxide,, Oxygen, nitrogen , Hydrogen, helium, Ozone ,chlorine, methane : Out of all these gases ...which ones are considered green house gases?

• Oxygen and chlorine

• Hydrogen and nitrogen

• Carbon dioxide and methane

• helium and ozone

Global winds distribute both of these around the Earth

• Transpiration and evaporation

• Heat and moisture

• Precipitation and drought

• Rain Shadows and deserts

The temperature of a body of water influences

• The temperature of the air above it

• The formation of deserts

• Vegetation patterns

• Global warming

The Koppen climate classification system is based on the following :

• Elevation and latitude

• Temperature and air pressure

• Precipitation and Location

• Temperature and precipitation

In 1991 Mt. Pinatubo, a volcano in the Philippines, exploded and sent thousands of tons of volcanic dust into the atmosphere. How did this affect the Climates of the world?

• Temperatures were cooler than normal

• Temperatures fluctuated to cooler and then hotter.

• Temperatures were warmer than normal

• The climate was not changed at all

Temperatures become cooler than normal due to natural processes like a volcanic eruption. What would cause this to happen?

• Caused by the reflection of sunlight due to a hole in the ozone layer

• Caused by heat spreading into the atmosphere by the eruption

• Caused by heat spreading by convection due to volcanic dust.

• Caused by the reflection of sunlight by all the volcanic dust

Low temperature and low precipitation describe which climate regions?

• humid tropical regions

• Cold temperate regions

• North and South Polar regions

• Equatorial regions

What is the best way to use a rain gauge to collect climate data?

• by collecting rain gauge data over several years

• by making single, very accurate observations

• by determining how much rain it takes to fill the rain gauge

• by determining the average amount of rain per rainstorm

What does this graph represent?

• The graph indicates climate limits.

• The graph shows climate over a long period of time.

• The graph provides an explanation of a yearly climate zone

• The graph shows current weather conditions in years.
