Why does air tend rise in equatorial regions group of answer choices?
The Trade Winds are one type of prevailing wind pattern. How many other types of prevailing winds are there among earth's global wind patterns? Why does air tend to rise in equatorial regions? Equatorial regions receive less indirect sunlight than other areas.
In which direction would wind move at the poles if Earth rotated in the opposite direction?
In which direction would winds move at the poles if Earth rotated in the opposite direction? –Wind would move toward the northeast at both poles.
Why do surrounding winds move near the equator?
The Coriolis Effect, in combination with an area of high pressure, causes the prevailing winds—the trade winds—to move from east to west on both sides of the equator across this 60-degree "belt."
How does the Coriolis effect cause the atmosphere to move around high and low pressures in the Northern Hemisphere?
As air tries to move from high to low pressure in the atmosphere, the Coriolis force diverts the air so that it follows the pressure contours. In the Northern Hemisphere, this means that air is blown around low pressure in an anticlockwise direction and around high pressure in a clockwise direction.
What causes air to rise in the atmosphere?
The most powerful force which causes air to rise and cool is the Sun. When the Sun heats the surface of the Earth, warming of the air above the ground takes place. This warm air rises and cools as it goes higher. At a certain point, condensation will occur and clouds will form.
Why Coriolis force is zero at equator?
Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object's path as measured relative to Earth's surface. The object's path is straight, that is, there is no Coriolis effect.
What causes the deflection of the wind from the poles to the equator and vice versa?
Our planet's rotation produces a force on all bodies moving relative to theEarth. Due to Earth's approximately spherical shape, this force is greatest at the poles and least at the Equator. The force, called the "Coriolis effect," causes the direction of winds and ocean currents to be deflected.
Is it windy at the equator?
Right at the equator there is almost no wind at all—an area sometimes called the doldrums.
Why is Coriolis zero at the equator?
Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object's path as measured relative to Earth's surface. The object's path is straight, that is, there is no Coriolis effect.
Why is there no deflection of winds at the equator?
Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator there is no curving of the object's path as measured relative to Earth's surface. The object's path is straight that is there is no Coriolis effect.
Why is the air so warm at the equator?
Regions around the equator absorb a lot of sun rays leading to warmer conditions, unlike the polar regions (the Arctic and Antarctica) which reflect a lot of sun rays due to the massive snow.
Why does rising air expand and cool?
A rising parcel of air expands because the air pressure falls with elevation. This expansion causes the air to cool. A falling parcel of air contracts because the air pressure increases. The contraction causes the air to warm.
Why does the earth spin faster at the equator?
Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.
What happens when you flush a toilet on the equator?
A big line is usually drawn which says "equator". Water is first emptied from a tub placed above this line, and it doesn't swirl much at all. Then, the water is drained on either side of the equator, and sure enough, the flow rotates in opposite directions on either side!
What causes the upward motion of the warm air?
As the molecules heat and move faster, they are moving apart. So air, like most other substances, expands when heated and contracts when cooled. Because there is more space between the molecules, the air is less dense than the surrounding matter and the hot air floats upward.
What will happen to the air from the north of the equator?
But because Earth is spinning, the air that moves north and south from the equator also turns with the spin of the Earth. Air going north turns to the right. Air traveling south turns to the left. The power of Earth's spin to turn flowing air is known as the Coriolis Effect.
What will happen to the air in the equatorial region?
In the tropics, near the equator, warm air rises. When it gets about 10-15 km (6-9 miles) above the Earth surface it starts to flow away from the equator and towards the poles. Air that rose just north of the equator flows north. Air that rose just south of the equator flows south.
Why there is no wind in equatorial region?
The area around the ITCZ is called the doldrums. Prevailing winds in the doldrums are very weak, and the weather is unusually calm. The ITCZ straddles the Equator. In fact, the low-pressure doldrums are created as the sun heats the equatorial region and causes air masses to rise and travel north and south.
Why does the Earth spin faster at the equator?
Specifically, Earth rotates faster at the Equator than it does at the poles. Earth is wider at the Equator, so to make a rotation in one 24-hour period, equatorial regions race nearly 1,600 kilometers (1,000 miles) per hour. Near the poles, Earth rotates at a sluggish 0.00008 kilometers (0.00005 miles) per hour.
Why centrifugal force is maximum at equator?
The equator is moving quickly as the earth's spins, so it has a lot of centrifugal force. In contrast, the poles are not spinning at all, so they have zero centrifugal force. Since centrifugal force points outwards from the center of rotation, it tends to cancel out a little bit of earth's gravity.
Why is Coriolis zero at Equator?
Because there is no turning of the surface of the Earth (sense of rotation) underneath a horizontally and freely moving object at the equator, there is no curving of the object's path as measured relative to Earth's surface. The object's path is straight, that is, there is no Coriolis effect.
Why is the climate hot and humid in the equatorial region?
Option (A ) hot and wet climate throughout the year is correct as these places, due to being close to the equator, have ample sunshine throughout and grow tropical rainforest.
How does rising air expand?
A rising parcel of air expands because the air pressure falls with elevation. This expansion causes the air to cool. A falling parcel of air contracts because the air pressure increases.

Why Coriolis force is maximum at pole and zero at Equator?
The force which deflects the direction of wind is called the deflection force or Coriolis force. This force generates due to the rotation of Earth. This force is zero at the equator and maximum at the poles due to the rotation of earth where Earth moves west to east or westward.
What is a Dutch toilet?
Arguably the most alarming feature of a Water Closet is the infamous Dutch toilet bowl. Dutch engineers have designed the bowl itself to contain a plateau set well above the normal water level. To say the least, one must be very comfortable with themselves and all their excrements on the display shelf.
Can you live on the equator?
If you live on the equator you will experience the quickest rates of sunrise and sunset in the world, taking a matter of minutes. These places also have a constant twelve hours of day and night throughout the year, while north or south of the equator day length increasingly varies with the seasons.
Where warm air rises up the air?
Where warm air rises up, the air pressure at that place is lower. The density of warm air is less which causes it to rise and this creates an area of low pressure.
Why does warm air rise and cold air sink?
Hot air rises, because it's less dense than cold air. Warm air in a room quickly rises upward, and cold air sinks downward, even if the tempera- ture differences are quite small. How do fluids carry heat from one place to another?
What causes air to rise?
Hot air rises because gases expand as they heat up. When air heats up and expands, its density also decreases. The warmer, less dense air effectively floats on top of the colder, denser air below it. This creates a buoyant force that causes the warmer air to rise.
