Why Does The Equator Receive More Solar Radiation


Why Does The Equator Receive More Solar Radiation?

The sun’s rays strike Earth’s surface most directly at the equator. This focuses the rays on a small area. Because the rays hit more directly the area is heated more. … The tilt of the Earth causes different areas to receive different amounts of solar energy.

Does the equator receive the most intense solar radiation?

Only locations lying along one line of latitude on the surface of the Earth can receive sunlight at a 90 degree angle on a given day. All other places receive sunlight at lesser intensities. In general the sun’s rays are the most intense at the equator and the least intense at the poles.

Why does the equator get more energy?

In the tropics there is a net energy surplus because the amount of sunlight absorbed is larger than the amount of heat radiated. … Areas around the equator absorbed about 200 watts per square meter more on average (orange and red) than they reflected or radiated.

Why does it receive direct rays from the sun?

The hemisphere that is more directly facing the Sun at a given point in Earth’s orbit receives more of the Sun’s energy. When the Sun is directly over your head you are receiving the Sun’s most direct rays.

Is the sun brighter at the equator?

So the equator area is getting more than twice as much light. We can easily see from this why the sun might appear very much brighter or dimmer depending on the angle and therefore depending on the latitude. This also explains the temperature difference: the equator is receiving a lot more energy so it gets hotter.

Why does the equator receive more solar radiation than Arizona?

The sunlight has less atmosphere to travel through It is near the rainforest. It is near the ocean which absorbs more solar radiation than the land surface. There are no seasons so it receives more solar radiation.

What causes the most direct solar radiation?

When the sun’s rays strike Earth’s surface near the equator the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore the solar radiation is concentrated over a smaller surface area causing warmer temperatures.

What angle will the equator receives the greatest solar energy?


For all latitudes outside the tropics as I’m sure we know the summer solstice is the date where the sun culminates the highest in the sky having the highest solar angle and insolation. This angle is 90° at the tropical circles.

Does the equator always receive direct sunlight?

The equator (yellow) is always hit by direct rays of the sun. This is why it is always warm there. The poles are always being hit by indirect rays.

Why does the equator receive equal day and night?

Why does the equator receive equal day and night? Because the circle of Illumination is bisecting all parallels which means that all latitudes are expecting 12 hours of day and night. what happens to the length of the day as you move north of the equator? the number of hours of daylight get longer.

Why is the equator warmest?

Why is it hot at the Equator and cold at the poles? Due to the tilt of the Earth the Equator is closer to the sun so receives more of its energy. The Equator has a smaller surface area so heats up quickly compared to the poles. There is less atmosphere to pass through at the Equator compared to the poles.

Why is the sun brighter at the equator?

Although the Sun appears to follow a yearly pattern of northward and southward motion in the sky causing unequal distribution of the energy of the Sun the Equator receives the same amount of energy during entire revolution of the Earth. Therefore the Sun is always Brighter at the Equator.

Where is the sun strongest on earth?

Latitude – The sun’s rays are strongest at the equator where the sun is most directly overhead.

When was day time the longest?

At about 21st June the sun is directly over the Tropic of Cancer providing the northern hemisphere with its longest day. In December the southern hemisphere enjoys its summer solstice when the sun is directly above the Tropic of Capricorn.

Why do two periods of maximum solar radiation occur at the equator?

Why are there two periods of maximum solar radiation at the equator? Vertical rays of the sun strike the equator and Earth’s position in its orbit is neither tilted away nor toward the sun. This happens during the equinoxes. … This energy is then emitted from the surface as longer wavelength radiation.

Why is it hotter at the equator than at the higher latitudes quizlet?

unequal radiation on a sphere: more solar radiation on a unit area of earths surface near the equator than at the poles because of the more direct angle of incoming solar radiation. At poles it is spread over a large area but at the equator over a small area so equator will be hotter than the poles.

Which part receives the least solar radiation explain your answer?


On an average those would be the poles. As you correctly pointed out due to the tilt of the Earth’s axis there are large areas that receive very little and sometimes no sunlight at all and those change throughout the year. But on an average poles are the ones that get the least amount of solar radiation.

How is the equator related to the amount of sunlight a climate zone receives?

How is the equator related to the amount of sunlight a climate zone receives? Heat is directed more towards the equator so a tropical zone located near the equator will have more sunlight.

Which type of energy causes the equator to be hotter than the North Pole?

solar energy

The amount of solar energy in a given area is greater at the equator than in an equal area at the poles which is why the equator temperature is warmer than the polar temperatures.

In what form does most solar radiation reach Earth?


Most of the solar radiation that reaches Earth is made up of visible and infrared light. Only a small amount of ultraviolet radiation reaches the surface.

At what angle does the earth recieve the greatest energy when does it happen?

The angle at which the sun’s rays reach Earth is directly related to the intensity of sunlight at the surface. Think of the flashlight experiment in class. 1. At high angles ( 65o-90o) the sun’s radiation is most intense.

Which type of radiation comes from the sun?

All of the energy from the Sun that reaches the Earth arrives as solar radiation part of a large collection of energy called the electromagnetic radiation spectrum. Solar radiation includes visible light ultraviolet light infrared radio waves X-rays and gamma rays. Radiation is one way to transfer heat.

What three things can happen to the radiation that Earth receives from the sun?

What three things can happen to the radiation that Earth receives from the Sun? It can either be reflected or radiated back out into space it can get absorbed by the atmosphere or it can reach the ground. In the atmosphere water vapor condenses to form clouds.

Why is the equator not the hottest place on earth?

This is because as the dry air descends from high altitudes its compression leads to an increase in its temperature. … Therefore air temperature in the tropics (42 degrees Celsius) is greater than that of the Equator (30 degrees Celsius). This is why tropical regions are hotter than the Equator.

How does equator affect climate?

Latitude or distance from the equator – Temperatures drop the further an area is from the equator due to the curvature of the earth. … This means that coastal locations tend to be cooler in summer and warmer in winter than places inland at the same latitude and altitude.

When did the direct rays of the sun falls on the equator?

On 21st March and September 23rd direct rays of the sun fall on the equator. At this position neither of the poles is tilted towards the sun so the whole earth experiences equal days and equal nights. This is called an equinox.

Why does the equator have 12 hours of sunlight?

The reason for this is because Earth is tilted 23.5 degrees away from its axis of rotation. If there were no tilt everywhere on Earth would receive 12 hours of daylight and 12 hours of night every day regardless of how close or far to the Equator.

What day has 12 hours of daylight and 12 hours of darkness?

September Equinox (Approximately September 22-23)

There are 12 hours of daylight and 12 hours of darkness at all points on the earth’s surface on the two equinoxes. Sunrise is at 6 a.m. and sunset is at 6 p.m. local (solar) time for most points on the earth’s surface.

Do the days get longer and shorter at the equator?

How does the length of day and night vary at the equator throughout the year? … Daylight at the equator is always a bit longer than darkness the result of the refraction of light through the atmosphere that allows us to see the sun a few minutes before it rises and a few minutes after it sets.

How do you explain the equator to a child?

An equator is an imaginary line around the middle of a planet or other celestial body. It is halfway between the North Pole and the South Pole at 0 degrees latitude. An equator divides the planet into a Northern Hemisphere and a Southern Hemisphere.

What is Earth’s equator?

The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles and divides the Earth into the Northern and Southern Hemispheres.

What is the hottest place in earth?

Death Valley
Death Valley California USA The aptly named Furnace Creek currently holds the record for hottest air temperature ever recorded. The desert valley reached highs of 56.7C in the summer of 1913 which would apparently push the limits of human survival.Sep 2 2021

Where is the sun in relation to the equator?

At the equator the noon sun is straight overhead on the equinoxes. And after you pass 23.5° south latitude (the Tropic of Capricorn) the noon sun is always in the north. Much farther south is the Antarctic Circle where the sun never quite rises on the June solstice and never quite sets on the December solstice.

What time is the sun the weakest?

Over time these “small” amounts of exposure add up and can increase your risk of developing skin cancer so it is important to plan your outdoor day-to-day activities during a time when the sun’s rays are at their weakest which is mainly during the early morning before 10 a.m. or early evening after 5 p.m.
