EARTH'S ATMOSPHERE
pressure belts due to this movement of hot and cold air
convection cells
location of the doldrums
equator
Most intense sunlight is received here
equator
Hot air is ________dense, while cold air is _______dense
less, more
Band of winds that travel opposite to the trade winds and the polar easterlies
What are the westerlies
Areas that receive NO sunlight for part of the year
N and S poles
Helps protect the Earth from the more dangerous forms of radiation
what is the magnetic field (magnetosphere)
excess of this gas contributes to global warming
carbon dioxide and greenhouse gases. (Methane, CO2, nitrous oxide, Water Vapor).
the "hot layer" of the atmosphere doesn't feel hot because there are so few particles
thermosphere
Causes winds on Earth
What is energy from the sun and rotation of the Earth?
Type of energy we can see
visible light spectrum
When the Sun's energy reaches the Earth's atmosphere, some of it is reflected back to space and some is absorbed and re-radiated by greenhouse gases. ... The absorbed energy warms the atmosphere and the surface of the Earth.
Greenhouse effect
gas in the atmosphere that is used by almost all organisms to make energy
oxygen
the layer where shooting stars occur the most
mesosphere
Term for the windless bands at 30 N and S
What are the horse latitudes?
reason the light intensity lowers as you move toward the poles
curvature of the Earth
protects the earth from UV radiation
Ozone layer
Layer in which most of the atmosphere is found
location where you would see shooting stars (meteors)
What is the mesosphere?
Reason that the winds bend differently in the N and S hemisphere
Coriolis effect
Source of the majority of energy on Earth
Sun
Common substance that heats and cools slowly
water
