Are the temperatures at all of the points along the Earths Equator the same?

Answer 1

The temperature at the equator, because day length is constant at 12 hours, does not vary with the seasons as it does at higher latitudes.

Instead, it varies with altitude, because the work done by rising air causes it to cool and as a result temperatures higher above the surface are cooler than at sea level. At the equator, temperatures cool up to 27,000 metres above sea level, an altitude known as the tropopause.

Typically, at sea level on the equator temperatures are a constant 30˚C (86˚F) by day and 25˚C (77˚F) by night. They fall by about 6˚C or 10˚F for every thousand metres of altitude, so that at an altitude of 4,600 metres the average temperature is 0˚C or 32˚F. (Although convective precipitation is not effective in such cold temperatures, it is still sufficient for the permanent snow line at the equator to be no higher than the 0˚C isotherm).

However, at high altitudes, owing to the intense sun and poor retention of heat in thin air with little CO2, diurnal temperature ranges are much higher than at sea level, so that at 3,000 metres temperatures will range from 16˚C (61˚F) in the daytime to 0˚C at night. At 4,600 metres it may vary from 10˚C in the day to -10˚C (14˚F) at night.

Answer 2

The main reason is because different areas of the earth have different amounts of exposure to sunlight - this is how seasons occur, because the tilting of the earth on its axis means that different areas are more or less exposed as the planet revolves around the sun.

This is not the only reason however - another reason is the existence of oceans and their interaction with land. Water is slower to change temperature than dry land, which means that sometimes oceans will be warmer than the surrounding land, and sometimes cooler.

The air over the oceans or the land reflect their tempreatures, so masses of cold and warm air form. These masses in turn interact with each other, which is what causes the air currents that move across the Earth. Hot air rises, so when a mass of hot air meets a hot of cool air, it will rush over it. This movement of currents causes differences in weather across the planet.

Exactly the same process occurs in the oceans with masses of cold and warm water to create ocean currents.

A final factor in the creation of temperature differences is the way that lanscapes cause weather. Mountain chains, for example, cause the air that meets them to rise rapidly. The moisture in this air is dropped as rain, which is why the climate will often be completely different on one side of a mountain range from the other, and why the side that faces the wind will be wetter than the far side.

Answer 3

No because the world is on a tilt, so the temperature is different everywhere.
