The Earth tilts on its axis which causes major differences to the amount of light that reaches the poles and extremes of Northern and Southern latitudes. The equatorial region is virtually unaffected by the seasonal tilt of the Earth and as such receives a large amount of light all year round.
Due to this the polar regions are significantly colder than the equatorial regions.
When a substance is heated the particles of that substance receive more kinetic energy; move more rapidly; move further apart; and therefore expand. When substances expand like this there are less particles per unit area and therefore the substance becomes less dense.
A less dense substance will float on top of a more dense substance.
Air is heated at equatorial regions and therefore rises due to decreased density.
Air is cooled at polar regions and therefore sinks due to increased density.
none of the suspected but just because it is a multiple choice question the one that is nearly the answer is sinking if it was rising the would be life at mars people going to the space wouldn't need air tanks with them
Actually, cool air tends to be more dense and flow under warm air
The air around the equator is caught in the doldrums and the trade winds. The air closest to the equator flows upward and westerly until it reaches the border of the prevailing westerlies when it heads back toward the equator again.
What causes these plates to move? The important thing to remember is that heat flows from warm areas to cool areas. In the asthenosphere you have some areas that are hotter than others. When the cool areas are heated up, their density decreases and they rise. Eventually, they cool, sink and repeat the process all over again. The result is a circular motion or current in the flowing part of the mantle. This process is called convection. Convection is also responsible for currents in the air.Hot air (a gas) rises near the equator and flows toward the poles, where it cools, becomes denser and sinks.
Wind direction is determined by friction ,or the lack thereof ,surrounding the earth surface. Warm air from the equator rises, moves towards the poles, falls and returns to the equator. crossing water decreases friction, crossing a mountain increases friction.
it sinks. since the equator is in direct contact with the sun, the poles are not. the are hit by the sun at a lower angle, and since the suns energy is spread out over a larger area, so it heats the surface less. as a result, temperatures near at the poles are much lower, and cold air sinks. at the equator, the temperatures are much higher, and the warm air is steadily rising. cold air comes, but it is quickly warmed and it rises. basically, warm air rises, cold air sinks. the equators warm, the poles are cold.
The air moves in a circular motion making a swirl around the equator. by: Unknown assasin
The reason the tropopause is lower above the poles than the equator is... The time it takes air to cool. The surface air-temperature at the equator is much higher than at the poles, meaning that the air rises further to reach the equilibrium required at the tropopause. Likewise, the air at the poles is cooler, and does not require as much room to rise.
Warm air rises at the equator and cold air sinks at the poles. Warm air expands and cool air contracts and compresses.
rise
Global winds drive heated air from the equator to the poles. It also drives colder air from the poles to the equator.
The difference in air pressure causes wind, air motion, because the greater the pressure difference the faster wind moves. Warm air is less dense, it moves toward or up to the poles. at the poles it will sink and the cold air will go to the equator creating the moment of of air.
c. sunlight falls in a more vertical position at the equator than near the poles.
yes

in the stratosphere
Since the equator is the closest point to the sun on earth,that means the heat from the sun heats up the air and water there more than at the poles
