The reflection of radiation is greatest at the poles because the incoming sunlight strikes the Earth's surface at a low angle, causing more of it to bounce off rather than be absorbed. Additionally, the white ice and snow present at the poles act as highly reflective surfaces, further increasing the amount of radiation that is reflected back into space.

Why is it cold at the poles?

The answer to this question involves the angle at which solar radiation is intercepted by the earth's atmosphere. The rule is that if solar radiation is incident perpendicular to the atmosphere the solar radiation that is incident on the earth's surface will be greatest. Incoming solar radiation at the poles comes in at a sharper angle and is spread over a greater surface area of atmosphere than at the equator. In this way, the poles have more of an atmospheric filter and experience less radiation per area time and hence have lower average temperatures.

What global region has the greatest annual input and least seasonal variation in solar radiation?

The equatorial regions near the equator have the greatest annual input of solar radiation with less seasonal variation compared to regions closer to the poles. This is because the equatorial regions receive more direct sunlight throughout the year due to their proximity to the sun's path.


Is the attractive force of a magnet greatest at its poles?

Yes, the attractive force of a magnet is greatest at its poles because this is where the magnetic field is strongest. The strength of the magnetic force decreases as you move away from the poles towards the center of the magnet.


What is the effect of radiation and light absorption and reflection?

Radiation absorption occurs when energy from radiation is transferred to a material, causing it to heat up. Reflection of light happens when light waves bounce off a surface rather than passing through it. These processes can have various effects depending on the material and the intensity of the radiation or light.


What area is the ozone depletion greatest?

The ozone depletion is greatest at the poles. It is due to the cold temperatures there.


Where are the greatest holes in the layers of ozone?

The greatest hole in the layers of ozone is at the poles. It is over Antarctica.


What type of radiation has the greatest range?

Gamma radiation has the greatest range among the types of radiation. It can travel far distances through various materials and can penetrate deeply into tissues.


Where is the magnetic force the greatest on a magnet?

The magnetic force of a magnet is strongest at its poles. This is because the field lines of the magnetic field are most concentrated at the poles where they enter and leave the magnet. At the poles the magnetic field is strongest and the force is the greatest. The north pole is where the magnetic field lines enter the magnet. The south pole is where the magnetic field lines leave the magnet. The magnetic field lines are most concentrated at the poles. The magnetic force is greatest at the poles.


On a bar magnet where are lines of magnetic force the greatest?

near both magnetic poles


Where does the earth emits radiation with greatest intensity at?

The Earth emits radiation with the greatest intensity in the infrared part of the spectrum, due to the thermal energy emitted by the surface. This is known as terrestrial radiation and plays a significant role in the Earth's energy balance.
