Which layer of the atmosphere is thicker over the equator than over the poles?

Which layer of the atmosphere is thicker over the equator than over the poles?

The atmosphere is divided into five different layers, based on temperature. The layer closest to Earth’s surface is the troposphere, reaching from about seven and 15 kilometers (five to 10 miles) from the surface. The troposphere is thickest at the equator, and much thinner at the North and South Poles.

Is the troposphere thicker than the stratosphere?

At the top of the troposphere is a thin layer in which the temperature does not change with height. This means that the cooler, denser air of the troposphere is trapped beneath the warmer, less dense air of the stratosphere.

What is the higher at the equator than the poles?

The Earth has a rather slight equatorial bulge: it is about 43 km (27 mi) wider at the equator than pole-to-pole, a difference which is close to 1/300 of the diameter. As a result, the highest point on Earth, measured from the center and outwards, is the peak of Mount Chimborazo in Ecuador rather than Mount Everest.

Is the atmosphere thinner over the poles?

This means at the north and south pole, the atmosphere is thinner than anywhere else on earth, because the air is pulled away from there. Ozone is in the same percentage all around the earth (because gasses diffuse % evenly) so it is natural that there is less at the poles.

Where is the ozone layer the thickest?

The amount of ozone above a location on the Earth varies naturally with latitude, season, and from day-to-day. Under normal circumstances, the ozone layer is thickest over the poles and thinnest around the equator.

What is above the troposphere?

The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. The ozone layer, which absorbs and scatters the solar ultraviolet radiation, is in this layer.

Can you breathe in the mesosphere?

The middle layer The mesosphere lies between the thermosphere and the stratosphere. The mesosphere is 22 miles (35 kilometers) thick. The air is still thin, so you wouldn’t be able to breathe up in the mesosphere. But there is more gas in this layer than there is out in the thermosphere.

Which country is closest to the equator?

The equator passes through the land of 11 countries and the seas of two others. It crosses land in São Tomé and Príncipe, Gabon, Republic of the Congo, The Democratic Republic of the Congo, Uganda, Kenya, Somalia, Indonesia, Ecuador, Colombia, and Brazil.

Where is gravity the strongest?

In general, the closer the centers of two objects, the greater the force of gravity becomes. Therefore, you would expect gravity in the United States to be stronger wherever you are closest to the center of the Earth.

Why the ozone hole is over Antarctica?

In the Southern Hemisphere, the South Pole is part of avery large land mass (Antarctica) that is completely surrounded by ocean. This chlorine and bromine activation then leads to rapid ozone loss when sunlight returns to Antarctica in September and October of each year, which then results in the Antarctic ozone hole.

Which country has the thinnest ozone layer?

Abnormal weather patterns in the upper atmosphere over Antarctica dramatically limited ozone depletion in September and October, resulting in the smallest ozone hole observed since 1982, NASA and NOAA scientists reported today.

Why is the troposphere thicker at the equator than at the Poles?

The hot air rises and the Earth is not equally heated everywhere. The troposphere is thicker over the equator than the poles because the equator is warmer. Heat differential on the planet’s surface causes convection currents to flow from the equator to the poles. This implies that the warmer the weather, the thicker is the troposphere.

Why are the poles closer to the Sun than the equator?

Earth’s orientation in space allows equator to be more closer to the Sun. Due to this higher gravity, atmosphere deforms slightly towards the sun while draining a bit more air from the poles. Regions near equator receives more sunlight than the poles making them hotter and less air dense.

Why is the atmosphere at the equator the deepest?

The primary reason that the atmosphere is deepest and thickest at the equator is because the air is, on average, warmer there than anywhere else on Earth. Warm air is less dense than cold air. And gravity exerts equal pressure worldwide, so atmospheric pressure is the same worldwide, weather systems aside.

How thick is the atmosphere at 50 degrees latitude?

Depths and degree of thickness gradually shift between these two extremes in the middle latitudes. For instance, at 50 degrees latitude, roughly the latitude of Seattle, Washington, the atmosphere is just under 10 kilometers (6 miles) thick.
