What is the order of layers in the atmosphere passage?
– Therefore, the order of earth’s atmosphere from bottom to top is the Troposphere, Stratosphere, Mesosphere, Thermosphere and Exosphere.
What’s the first layer of the atmosphere?
The troposphere starts at the Earth’s surface and extends 8 to 14.5 kilometers high (5 to 9 miles). This part of the atmosphere is the most dense. Almost all weather is in this region. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high.
Why are the four major layers of the atmosphere separated?
The atmosphere is divided into layers based on how the temperature in that layer changes with altitude, the layer’s temperature gradient. The temperature gradient of each layer is different. In some layers, temperature increases with altitude and in others it decreases.
What is the correct order of the atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the troposphere, stratosphere, mesosphere and thermosphere.
What is the first layer of the atmosphere?
The first layer of the Earth’s atmosphere, troposphere starts from the surface of the planet and extends up to a vertical distance of 4.34 miles near the poles and 10.56 miles near the equator. The temperature of troposphere decreases with altitude, which means that the lowest part of the layer is the warmest at any given point of time.
What is the bottom layer of the atmosphere called?
Earth’s atmosphere consists of a number of layers that differ in properties such as composition, temperature and pressure. The lowest layer is the troposphere, which extends from the surface to the bottom of the stratosphere.
What are the characteristics of the atmosphere?
physical characteristics of the atmosphere. The atmosphere is like an ocean of air that surrounds the surface of the Earth. It is a mixture of water and gases. The atmosphere extends from the surface of the Earth to about 1,200 miles in space.
What is the temperature range of the atmosphere?
The thermosphere is typically about 200° C (360° F) hotter in the daytime than at night, and roughly 500° C (900° F) hotter when the Sun is very active than at other times. Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher.
