Why are temperatures warmer near the equator than near the poles?
the sun in every season hits that are more than any spot on earth the poles receiving the least amount due to the fact they are pushed back a bit, also areas surrounded or near water happen to be hotter on the equator.
Why is cosine used in finding ditance traveed on a latitude?
The distance along one degree of longitude is 60 nautical miles at the equator and less at latitudes away from the equator. In fact it is 60 nautical miles times the cosine of the latitude, so 60 at the equator zero at the poles, and 30 nautical miles at 60 degrees north or south..
What effect does the coriolis effect have on ocean currents?
The Coriolis effect results in a deflection of fluid flows (to the right in the Northern Hemisphere and left in the Southern Hemisphere). Because the distance around the Earth decreases as one moves away from the equator, and because the Earth rotates in a counter clockwise direction as seen from the north pole, air and water masses are deflected to the east as they move from the equator to the poles, and to the west as they move from the poles to the equator. This has profound effects on the flow of the oceans. In particular it means the flow goes around high and low pressure systems, permitting them to persist for long periods of time. As a result, tiny variations in pressure can produce measurable currents. A slope of one part in one million in sea surface height, for example, will result in a current of 1 cm/s at mid-latitudes. The fact that the Coriolis effect is largest at the poles and weak at the equator results in sharp, relatively steady western boundary currents which are absent on eastern boundaries
Why does the area near the poles receive less heat?
The atmosphere around the earth is like a blanket to protect us from the harmful rays of the sun. When the sun shines straight down like near the equator, there is less atmosphere between the earth and the sun to block the energy. Near the poles, the atmosphere is thicker because the sun is shining down at an angle and it has to go through more of the blanket of the atmosphere before it touches the earth. During the winter, each pole is in total darkness nighttime because that area of the pole is behind the earth also. These areas near the poles are called the Arctic circle and the Antarctic Circle. Because of the angle to the sun. At the equator the sun light hits the Earth surface pretty much perpendicularly, but at the poles it's a much more oblique angle. lighter colors reflect light and heat and the ice at the poles are white and reflect more also trees are not found at the poles and they can trap heat
Why does lightning strike the most on the Equator?
It has to do with the fact the climate is warmer near the equator.

What is Saturn's temperature range and high and low?
The average temperature at the "surface" of Saturn is about minus 150 degrees Celsius. In fact that doesn't vary much from poles to equator. So, there not much of a maximum and minimum.

What causes westerlies?
The westerlies are the prevailing direction whence winds and weather move in the northern hemisphere.It starts with the fact that the sun hits the Equator more directly than the poles (in this most basic, simple description), making the surface air near the Equator relatively hot and the air near the pole relatively cold. Hot air being less dense and more buoyant than cold, convection causes the warm Equatorial air to rise while the colder polar air sinks.Among other effects, this leads to higher air pressure in the middle levels of the atmosphere near the Equator (because air is buoyant and lifting into, or being added to, this part of the atmosphere) and lower pressure at mid-levels near the poles (because air is dense and sinking away from mid-levels of the atmosphere). So now you have, off the immediate Earth's surface (but even to some extent at the surface), higher air pressure near the Equator and lower air pressure near the poles. Nature and the laws of physics try to eliminate this pressure difference, meaning that air flows from areas of higher pressure toward areas of lower pressure to even things out - at least that's its intent.This is where the Coriolis effect kicks in. On a non-rotating surface, air moves from higher pressure to lower pressure, directly perpendicular to the gradient (change in pressure with distance). But because of the Earth's rotation, this air flow is spun, in a sense, such that it is almost but not quite parallel to the gradient, keeping lower pressure to its left and higher pressure to its right (it is actually we and the Earth that spin beneath the air, but that is not the way humans on this rotating surface experience it).Because of the direction the Earth spins, and because of the air movement dictated by all the factors above, the over-simplified result is a band of air that encircles the middle latitudes of the northern hemisphere, with winds that flow from west to east; high pressure near the Equator to its right (south in this case) and the lower polar air pressures to its left. These winds in their more complicated realistic state - stronger here, weaker there, buckled here, warped there, with waves interacting in often complex ways - drive weather systems, and generally keep them moving from west to east - that's the PREVAILING situation anyways - hence "prevailing" westerlies.
Is the gravity more in the pole or in the equator?
THEORETICALLY the answer to your question is yes. Locations at the poles are both closer to the center of the earth and are not accelerated tangentially by the rotation of the planet.The latitudinal variation results from the fact that the Earth is not round like a ball but is more pancake shaped (it is fatter round the equator - the equatorial bulge at the equator is measured at 26.5 miles (42.72 km), the shape of an 'oblate spheroid'.This shape is caused by the fact that the Earth is spinning which means 'stuff' at the equator is moving round faster than 'stuff' at the poles and this flings it away form the centre of the Earth. The faster spin at the equator produces an outward centrifugal force which counteracts the Earth's gravity to a small degree, reducing downward acceleration of falling objects. Thus at the equator, this apparent gravity is 0.3% less than actual gravity.However, things are more complex - if the Earth were an inert sphere of uniform density, you could work out (model) what the gravity aught to be at any point on its surface (this is called the geode). However, if you go out and measure gravity at various points on the Earth, the values you get are different from this theoretical model because the actual strength of Earth's gravity varies with latitude, altitude, local topography and the underlying geology (the density of the rocks below you). These factors can cause a actual gravity reading to far exceed modeled predictions relating to the variation between the equator and the poles.
What is the literal meaning of Ecuador?
Ecuador means "equator" in Spanish, referencing the fact that the country straddles the equator in South America.
The revolution of the earth causes the seasons right?
No, the revolution of the Earth (its spin about an axis through the north and south poles) causes night and day. The Seasons are cause by the fact that the Earth's spin axis is tilted and by the orbit of the Earth round the Sun.
