Is the troposphere the thickest over the equator?
The troposphere is thickest at the equator, and much thinner at the North and South Poles. The majority of the mass of the entire atmosphere is contained in the troposphere—between approximately 75 and 80 percent.
What is the thickest layer over the equator?
The troposphere is where we live; it's the layer closest to the surface. It extends 5-10 miles high and is thinnest at the poles and thickest at the equator.
Why is troposphere thicker at equator?
Thickness of the troposphere is greatest at the equator because heat is transported to great heights by strong convectional currents. This layer contains dust particles and water vapour. All changes in climate and weather take place in this layer.
Which layer is the thickest of the atmosphere?
Thermosphere. The thickest layer in the atmosphere is the thermosphere starting at about 80 km and going upwards.
How thick is the troposphere?
between 5 and 9 miles The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. It's thinnest at the North and South Pole. This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer.
What is the thinnest layer of the atmosphere?
The troposphere The troposphere is also the thinnest layer, only about 10 miles high. The second layer up from the ground is the stratosphere. This layer extends from about 10-30 miles, and unlike the troposphere, it increases in temperature with elevation. It starts out from about -60°F at the bottom to about 32°F, at the top).
What is troposphere layer?
The troposphere is the lowest layer of the atmosphere, ranging from the Earth's surface to an altitude of about 10–15 km, depending on latitude and time of year.
How thick is the equator?
The Earth's diameter at the Equator is about 12,756 kilometers (7,926 miles). At the poles, the diameter is about 12,714 kilometers (7,900 miles). The Earth's equatorial bulge is about 43 kilometers (27 miles).
Where is the thickest part of the troposphere?
the equator The troposphere is shallowest — or narrowest — at the poles, and deepest — or thickest — at the equator. At the geographic North and South Poles, the troposphere reaches only 6 kilometers (4 miles) high, while at the equator, it extends nearly 20 kilometers (12 miles) high.
What is the thickness of troposphere?
The troposphere is between 5 and 9 miles (8 and 14 kilometers) thick depending on where you are on Earth. It's thinnest at the North and South Pole. This layer has the air we breathe and the clouds in the sky. The air is densest in this lowest layer.
Where is the atmosphere thicker at the equator or the poles explain?
The Reason: Temperature Therefore, the same amount of air molecules over the equator must extend further upward than the air molecules in the coldest regions on Earth, the poles. Thus, the atmosphere is thickest and deepest at the equator, as the air molecules take up far more space there than anywhere else.
What is the thickness of atmosphere?
The Earth's atmosphere is an extremely thin sheet of air extending from the surface of the Earth to the edge of space. The Earth is a sphere with a roughly 8000 mile diameter; the thickness of the atmosphere is about 60 miles.
What is troposphere answer?
The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
What is on the equator?
The equator passes through 13 countries: Ecuador, Colombia, Brazil, Sao Tome & Principe, Gabon, Republic of the Congo, Democratic Republic of the Congo, Uganda, Kenya, Somalia, Maldives, Indonesia and Kiribati.
Why is the troposphere higher at the equator and lower at the poles?
Air is less dense at Equator. Poles Exert more gravitational pull on atmospheric gases. The centrifugal force due to Earth's rotation is maximum at Equator. Chemical Composition of Troposphere.
Why the height of tropopause is greater at equator?
This site says that the tropopause is at a higher altitude at the equator because: Gravitational force from a point is higher closer to it and reduces with increasing distance from it. Because the Earth itself is broader at equator, the equator experiences less gravity allowing air to reach bigger heights.
What is meant by thickness of the troposphere?
"Thickness" is a measure of how warm or cold a layer of the atmosphere is, usually a layer in the lowest 5 km (17,000 feet) of the troposphere; high values mean warm air, and low values mean cold air.
Is the equator the hottest?
So the concept that the hottest place on earth is around the equator and the coolest is on the poles is wrong. It is hotter in the desert than around the equator because the weather in the desert is very dry so when the temperature rises and it doesn't rain the temperature will rise even higher ….
What is the thickness of tropopause?
The TL's top shows the similar latitudinal variation as the bottom but with the smaller range from 15 km over equator to 19 km over poles. As a consequence, the climatological thickness of TL becomes thicker from 2.6 km to ∼7 km with latitude increment.
What is the thickness of the atmosphere?
about 60 miles The Earth's atmosphere is an extremely thin sheet of air extending from the surface of the Earth to the edge of space. The Earth is a sphere with a roughly 8000 mile diameter; the thickness of the atmosphere is about 60 miles.
Why is it called the equator?
The name is derived from medieval Latin word aequator, in the phrase circulus aequator diei et noctis, meaning 'circle equalizing day and night', from the Latin word aequare 'make equal'.
Why is equator so hot?
Ultimately, the temperature in an area depends on the amount of the Sun's energy reaching the surface in that area. 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.
Why troposphere is thicker at equator and thinner at poles?
Thickness of Troposphere 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.
Is the equator hot?
Countries on, or near, the equator have high temperatures all year round due to the tilt of the Earth's axis. The average temperature in these countries is around 31 degrees Celsius. Because there are landmasses that the equator passes through, you can stand on the equator!
Why Africa is so hot?
The continent mainly lies within the intertropical zone between the Tropic of Cancer and the Tropic of Capricorn, hence its interesting density of humidity. Precipitation intensity is always high, and it is a hot continent.
Does the equator have seasons?
Countries near the equator don't experience the four seasons like other places on Earth do. Countries on, or near, the equator have the same amount of daylight and darkness throughout the year. Generally, there are two seasons in equatorial countries, wet and dry. The wet season lasts most of the year.
Why is the tropopause colder over the equator?
As the temperature decreases with height, so the temperature at the tropopause over the poles will be higher than over the equator because the tropopause is closer to the ground here. This is the opposite situation to the surface temperature.
Why Is Arabia so dry?
The Sahara and the Middle East are dry in part because they straddle the the Tropic of Cancer. But the Tropic of Cancer isn't dry everywhere.
Is Asia hot?
The Southern sections of Asia are mild to hot, while far northeastern areas such as Siberia are very cold, and East Asia has a temperate climate. The highest temperature recorded in Asia was 54.0 °C (129.2 °F) at Tirat Zvi, Israel on June 21, 1942 and at Ahvaz, Iran on June 29, 2017.
Why troposphere is thicker at equator and thin at poles?
Thickness of Troposphere 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.
