Unequal heating of Earth,
atmospheric convection
What causes the uneven heating of the earth quizlet?
the sun
heats the earth unevenly in two different ways. Direct rays hit the equator and therefore make it hot. … The surface of the Earth heats at different rates. Land heats faster than water.
What causes the uneven heating of the earth?
The answer is due to uneven heating of the Earth
by the sun
. … When the earth orbits the sun, the center of the Earth gets more direct sunlight than the poles. This is exacerbated by the Earth’s tilt. Since the center of the Earth gets more sunlight, it is consistently hotter than other parts of the Earth.
Wind is the movement of air caused by the
uneven heating of the Earth by the sun
. … Warm equatorial air rises higher into the atmosphere and migrates toward the poles. This is a low-pressure system. At the same time, cooler, denser air moves over Earth’s surface toward the Equator to replace the heated air.
How does the uneven heating of the Earth affect the atmosphere?
Earth’s orbit around the sun and its rotation on a tilted axis causes some parts of Earth to receive more solar radiation than others. This uneven heating
produces global circulation patterns
. For example, the abundance of energy reaching the equator produces hot humid air that rises high into the atmosphere.
What are the two main factors that contribute to uneven heating of the earth?
The factors that contribute to the uneven heating of the Earth by the sun include
latitude, seasons, and the time of the day
.
What is it called when fluid moves due to uneven heating?
Convection
occurs in fluids, such as water and air. But. some convection occurs in solids that can flow like putty. The uneven heating of matter drives convection.
What is most responsible for the uneven heating of the air in the atmosphere?
The movement of air through Earth’s — or any planet’s — atmosphere is called wind, and the main cause of Earth’s winds is uneven
heating by the sun
. This uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.
Why is there an uneven heating of the Earth Class 7?
The Wind is caused by air moving from areas of high pressure to areas of low pressure. It is produced by the uneven heating of the earth’s surface
by the Sun
. … Warm air, which weighs less than cold air, rises. Cool air moves in and replaces the rising warm air.
Does convection cause uneven heating?
Convection works when
a liquid or gas is unevenly heated
. Hot liquids (and gases) are less dense and rise, causing.
What are some effects of unequal heating?
Unequal heating of the earth’s surface causes
temperature differences which cause pressure differences
. Lower temperatures (heavy air) cause higher air pressure. Wind direction is described as where the wind is coming from. For example a northerly wind blows from the north to the south.
What happens to the energy that Earth receives?
The energy that Earth
receives from sunlight is balanced by an equal amount of energy radiating into space.
The energy escapes in the form of thermal infrared radiation: like the energy you feel radiating from a heat lamp. (NASA illustrations by Robert Simmon.)
What defines climate?
Climate is
the long-term pattern of weather in a particular area
. Weather can change from hour-to-hour, day-to-day, month-to-month or even year-to-year. A region’s weather patterns, usually tracked for at least 30 years, are considered its climate. Climate System. Different parts of the world have different climates.
What causes the Coriolis effect?
Because the Earth rotates on its axis, circulating air is deflected toward the right in the Northern Hemisphere and toward the left in the Southern Hemisphere
. This deflection is called the Coriolis effect.
What makes the temperature change?
Earth’s temperature depends on the balance between energy entering and leaving the planet’s system. … Variations in the sun’s energy reaching Earth. Changes in the reflectivity of Earth’s atmosphere and
surface
.
Changes in the greenhouse effect
, which affects the amount of heat retained by Earth’s atmosphere.
How does air move in general?
Air in the atmosphere moves around the world in a pattern called global atmospheric circulation. … When
the air cools, it drops back to the ground, flows back towards the Equator, and warm again
. The, now, warmed air rises again, and the pattern repeats. This pattern, known as convection, happens on a global scale.
