Global winds move warm air toward the poles.
As latitude decreases,
solar energy increases
Rain forests only cover 6% of the Earth's surface, but are believed to contain almost two-thirds of the planet's species.
The greenhouse effect is a man made condition that affects the quality of our atmosphere.
Short-term climate fluctuations CANNOT be caused by
tectonic plate movement

Which climate is NOT one of the principal groups in the Koppen system?
Humid tropical climate regions are located
On either side of the equator
How do large bodies of water influence climate
Tundras can occur because of a high elevation or a far northern latitude
According to the Koppen climate classification system,
Humid tropical climates do not experience winters
Which of the following describes how vegetation influences precipitation?
A dry climate is one in which the yearly precipitation is lower than the loss of water to evaporation.
The more the earth is tilted, the ________ the temperature difference between summer and winter
How does Earth's tilt affect climate?
The smaller the tilt, the smaller is the temperature difference between summer and winter

The climate is the temperate zone in
warm in summers and cold in winters
Explain why length of daylight throughout the year is fairly constant in the tropics
The length in daylight throughout the year is fairly constant in the tropics because it is located near the equator and has more solar energy their.
A storm known as a nor'easter is the result of the action of a maritime polar air mass out of eastern Canada.
In an anticyclone, the value of the isobars increases from the center to the outside.
an east wind blows from --- to ---
List the 4 main types of air masses and tell where they form.
The greater the difference in air pressure the--- the wind speed is.
