BIO 1010 Exam 4 Questions with Correct Answers Latest Update 2025/2026
What is the primary cause of climatic patterns on Earth? - Answers The primary cause of
climatic patterns on Earth is the uneven distribution of solar radiation due to the tilt of the
Earth's axis and its curvature.
How much solar radiation is reflected back to space? - Answers Approximately 30% of solar
radiation is reflected back to space, while the rest is absorbed by the atmosphere and the
Earth's surface.
How does the intensity of solar radiation vary with latitude? - Answers The intensity of solar
radiation decreases as latitude increases, meaning it is strongest at the equator and weaker at
the poles.
What happens when light travels farther through the atmosphere? - Answers As light travels
farther through the atmosphere, it is scattered and absorbed, reducing its intensity by the time it
reaches the surface.
Where on the planet is the most solar energy absorbed at the surface? - Answers The most
solar energy is absorbed at the equator, where sunlight is most direct.
How does the tilt of the Earth and its rotation around the Sun influence climate? - Answers The
tilt of the Earth affects the angle of sunlight received at different latitudes, leading to seasonal
variations in climate.
What are Hadley, Ferrel, and Polar cells? - Answers Hadley, Ferrel, and Polar cells are large-scale
atmospheric circulation patterns that distribute heat and moisture around the Earth.
Can you describe the movement of air in Hadley cells? - Answers In Hadley cells, warm air rises
at the equator, moves toward the poles at high altitudes, cools and sinks around 30° latitude,
then returns to the equator at the surface.
Where does air in Hadley cells subside? - Answers Air in Hadley cells subsides around 30° N and
30° S latitude.
How are air temperature and the amount of water in air related? - Answers Air temperature is
directly related to the amount of water vapor it can hold; warmer air can hold more moisture.
Why are the tropics wet? - Answers The tropics are wet due to the rising warm air that cools and
condenses, leading to high precipitation.
Why are deserts located near 30° N and 30° S latitude? - Answers Deserts are located near 30° N
and 30° S latitude due to the subsiding dry air from Hadley cells, which inhibits precipitation.
What is the cause of rainy seasons in the tropics? - Answers Rainy seasons in the tropics are
caused by the seasonal migration of the Intertropical Convergence Zone (ITCZ), where trade
, winds converge and cause heavy rainfall.
Why is temperature more variable in the northern hemisphere than the southern hemisphere? -
Answers Temperature is more variable in the northern hemisphere due to the larger landmass,
which heats and cools more rapidly than oceans.
Can you describe the Coriolis Effect? - Answers The Coriolis Effect is the deflection of moving
objects, such as air, due to the rotation of the Earth, causing winds to curve.
How does air move from the equator toward the poles and vice versa? - Answers Air moving
from the equator toward the poles is deflected eastward due to the Coriolis Effect, while air
moving toward the equator is deflected westward.
How are ocean currents and wind patterns on the surface of the Earth related? - Answers Ocean
currents are driven by wind patterns, which create friction and transfer energy to the water,
influencing climate and weather.
What causes upwelling on the west side of continents? - Answers Upwelling on the west side of
continents is caused by the divergence of surface currents, which allows deeper, nutrient-rich
water to rise.
How do ocean currents affect the climate on the east and west sides of continents? - Answers
Ocean currents can warm or cool coastal regions, with warm currents leading to milder climates
on the east side and cold currents contributing to cooler climates on the west side.
Why are the interiors of continents drier than maritime areas? - Answers The interiors of
continents are drier because they are farther from moisture sources like oceans, leading to less
precipitation.
What happens when air moves up the side of a mountain? - Answers When air moves up the
side of a mountain, it cools and expands, leading to condensation and precipitation on the
windward side.
What is a rain shadow? - Answers A rain shadow is a dry area on the leeward side of a mountain
range, where air descends and warms, reducing precipitation.
Can you name two large deserts created by a rain shadow? - Answers Two large deserts created
by a rain shadow are the Atacama Desert in Chile and the Great Basin Desert in the United
States.
What controls temperature variability on Earth? - Answers Temperature variability on Earth is
controlled by factors such as solar radiation, atmospheric composition, ocean currents, and
geographical features.
Can you name three greenhouse gases? - Answers Three greenhouse gases are carbon dioxide
(CO2), methane (CH4), and nitrous oxide (N2O).
What is the primary cause of climatic patterns on Earth? - Answers The primary cause of
climatic patterns on Earth is the uneven distribution of solar radiation due to the tilt of the
Earth's axis and its curvature.
