Climate pt. 2 Flashcards
What causes the seasons?
a) The shape of Earth’s orbit causes the Earth to be closer to the sun during
some parts of the year (summer) and farther from the sun during other
parts of the year (winter)
b) The tilt of Earth on its axis causes the amount of solar radiation received
to vary throughout the year, at any given location
c) The latitude of a region causes the amount of sun received at that
specific location to vary throughout the year
d) The amount of light reflected away from Earth’s surface is greater in the
winter, causing temperatures to decrease.
b) The tilt of Earth on its axis causes the amount of solar radiation received
to vary throughout the year, at any given location
When does the northern hemisphere receive more sunlight?
Between:
March 20 and September 22
When does the southern hemisphere receive more sunlight?
Between:
September 24 and March 18
Why do parts of Alaska, located at about 60 degrees N, receive about 21 hours of sunlight in June and about 20 hours of darkness in January?
In June, would it be warmer in Alaska (60 degrees N, about 20 hrs of sunshine) or Mexico City (20 degrees N, about 13 hrs of sunshine)? Why?
What causes seasonal precipitation?
Earth’s tilt (warm air can hold more water vapor than cold)
What is the region that receives high levels of sunlight and rainfall?
the Inter-Tropical Convergence Zone (ITCZ)
Where is the ITCZ in March and September?
around the equator
Where is the ITCZ in December?
South of the equator
Where is the ITCZ in June?
North of the equator
What is the Tropic of Cancer during June Solstice?
solar equator is around 23.5 degrees NORTH (spot that actually receives the most intense sunlight)
Equator (0 degrees N/S)
What is the Tropic of Capricorn during December Solstice?
solar equator is around 23.5 degrees SOUTH (spot that actually receives the most intense sunlight)
Equator (0 degrees N/S)
