a flat solar panel
a photovoltaic panel
a photovoltaic cell
a system for heating water

Half of the sunlight entering Earth’s atmosphere reaches Earth’s surface. What happens to the rest?
It returns to the sun.
It is absorbed or reflected by the atmosphere.
It is absorbed and stored in the global oceans.
It is reflected to the moon, causing the moon to appear bright.
Sunlight is made of different wavelengths of energy. Shorter wavelengths
are less powerful than longer wavelengths.
travel less distance than longer wavelengths.
carry more energy than longer wavelengths.
make up the bulk of all sunlight reaching the atmosphere.
The waves of sunlight most important to weather are
laser, mechanical, and magnetic.
gamma, x-ray, microwave, and radio.
the longest waves that can reach the atmosphere.
ultraviolet light, visible light, and infrared light.
________ are gases in the atmosphere that absorb the energy of infrared light.
Greenhouse gases
Helium and argon
Nitrogen and neon
Solar gases
The greenhouse effect warms up the atmosphere, which in turn, warms up what?
beams.
Solar rays.
rods.
spears.
Which statement is true?
Sunlight is less concentrated at different latitudes.
Sunlight has no effect on weather.
Sunlight warms all locations the same amount.
Sunlight is weakest near the equator and strongest near the poles.
The amount of sunlight during the day depends on
the time of day.
whether cloud cover is thin or heavy.
the angle at which the sun's rays strike Earth's curved surface.
how much light is reflected from the moon and combined with sunlight.
Thermal energy flows from _________ to __________.
low precipitation; high precipitation
high temperature; low temperature
north; south
Earth; sun
What would happen if the sun's energy stayed in one place and didn't travel?
Temperature differences between places of high and low latitude would be more extreme.
The sun's energy would be intensified and radiated back towards the sun causing solar flares.
The atmosphere would absorb all of the sun's energy, so it wouldn't make much difference.
There would be no temperature difference between locations so the entire planet would be hot.
Energy transfer from the atmosphere to ocean move by
conduction.
convection.
location.
radiation.
As the ocean and atmosphere move energy around, the temperature changes they bring affect
Earth's orbit.
the amount of daylight.
the weather.
greenhouse gases.
Changes in the ______ at which sunlight strikes Earth causes the seasons.
angle
distance
intensity
temperature
What happens when the Northern Hemisphere tilts toward the sun?
Earth wobbles slightly off of its axis, causing earthquakes and severe weather.
The sun's rays are at a greater angle, providing less energy. It is winter.
The sun's rays hit it more directly, providing more energy. It is summer.
The Southern Hemisphere heats up and then transfers thermal energy northward.
When the Northern Hemisphere experiences summer, the Southern Hemisphere
A. experiences winter.
experiences summer.
is completely in the dark.
receives more energy.
