Ecology Chapter 2

what is the difference between climate and weather

• Climate is hot, weather is cold
• Climate is predictable, weather is unpredictable
• Climate is related to geography, weather is related to time of day
• Climate is long-term, weather is short-term

typical atmospheric conditions that occur throughout the year, measured over many years

What is the greenhouse effect

• The greenhouse effect is the process of solar radiation, and being absorbed and re-emitted by atmospheric gases

• The greenhouse effect is the process by which the Earth's atmosphere cools down the planet's surface
• The greenhouse effect is the process by which the Earth's atmosphere has no impact on the planet's temperature
• The greenhouse effect is the process by which plants trap heat from the sun

Answer explanation

examples: CO2/factory emission, burning of fossil fuels

how humans impact greenhouse gas release: cars/not carpooling etc.

The albedo effect: what is Albedo?

• The fraction of solar energy reflected by an object

• The distance between the Earth and the Moon
• The boiling point of water
• The speed of sound in a vacuum

Answer explanation

surfaces with lighter colors will typically reflect more

ex: asphalt (hotter) vs. sidewalk

Seasonal variation in climate results from:

• The rotation of the moon around the Earth
• The movement of the Earth's tectonic plates
• The gravitational pull of the other planets in the solar system
• Tilt of the Earth's axis and its orbit around the sun

Answer explanation

changes sun angle and day length

What do atmospheric currents do

• Circulate air between the surface of the Earth and the atmosphere

• Control the migration patterns of birds
• Create new planets in the solar system
• Cause earthquakes and tsunamis

Answer explanation

they play role in location of different biomes

note: WARMER AIR HOLDS MORE WATER VAPOR
