What is the distance from sea level to the troposphere?
The troposphere extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. The height of the top of the troposphere varies with latitude (it is lowest over the poles and highest at the equator) and by season (it is lower in winter and higher in summer).
What is the distance of the troposphere?
The troposphere begins at the Earth’s surface and extends from 4 to 12 miles (6 to 20 km) high. The height of the troposphere varies from the equator to the poles.
What is the temperature range in the troposphere?
Temperatures at the tropopause range from as low as −80 °C (−112 °F) in the tropics to −50 °C (−58 °F) in polar regions.
Which layer is closest to sea level?
troposphere—the layer closest to Earth’s surface in which all weather occurs.
What’s the hottest layer of earth?
the inner core
The core is the hottest, densest part of the Earth. Although the inner core is mostly NiFe, the iron catastrophe also drove heavy siderophile elements to the center of the Earth.
What are the 4 characteristics of troposphere?
Characteristics of troposphere
- it is the first atmospheric layer closet to Earth’s surface.
- the troposphere is the region where weather occurs.
- the temperature of troposphere decreases with an increase in height.
- the troposphere makes up approximately 75% of Earth’s atmosphere by mass.
What is an example of troposphere?
The troposphere is the lowest layer of the atmosphere with water vapor, vertical winds and temperatures that decrease as the altitude increases. An example of the troposphere is the layer below the tropopause. The weather, major wind systems, and cloud formations occur mostly in the troposphere.
Is troposphere hot or cold?
The troposphere, the lowest layer of Earth’s atmosphere, is heated from below. The troposphere is warmest at the bottom near Earth’s surface. The troposphere is coldest at its top, where it meets up with the layer above (the stratosphere) at a boundary region called the tropopause.
What is the relationship between temperature and height in troposphere?
Temperature varies with altitude, as follows: In the troposphere, temperature decreases as altitude increases. In the stratosphere, temperature generally increases as altitude increases due to the increasing absorption of ultraviolet radiation by the ozone layer.
Which is the coldest layer?
The top of the mesosphere is the coldest area of the Earth’s atmosphere because temperature may locally decrease to as low as 100 K (-173°C).
What are facts about the stratosphere?
Interesting Stratosphere Facts: The stratosphere is one of five layers of the atmosphere. The word ‘stratosphere’ is derived from the word ‘strato’ meaning layer, and ‘sphere’ which is earth’s shape. The stratosphere accounts for approximately 24% of the earth’s total atmosphere.
How high up is the stratosphere?
The height of the bottom of the stratosphere varies with latitude and with the seasons. The lower boundary of the stratosphere can be as high as 20 km (12 miles or 65,000 feet) near the equator and as low as 7 km (4 miles or 23,000 feet) at the poles in winter.
How thick is the 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.
What can you see in the troposphere?
Deep oranges and yellows appear in the troposphere, which extends from the Earth’s surface to 6–20 km high. This layer contains over 80 percent of the mass of the atmosphere and almost all of the water vapor, clouds, and precipitation. Several dark cloud layers are visible within this layer.
