Atmosphere layers
How are satellites important in the exosphere?
Signals bounces off a satellite in the exosphere before it goes to Earth. The satellite is a machine that is used to have all day watch to see the weather. In the exosphere there are artificial satellites that orbit the Earth.
What is the atmosphere?
The atmosphere is layers of air around the Earth.
What is the atmosphere made up of?
The atmosphere is made of a mixture of gases mainly nitrogen, oxygen, argon and carbon dioxide and other gases.
How big is the thermosphere?
The thermosphere goes from 80 kilometers above the Earth's surface to more than 3,200 kilometers above the Earth's surface. The thermosphere starts at 80 kilometers above the Earth's surface.
What is the temperature of the thermosphere?
The thermosphere is the hottest layer. The air is really thin. Not a lot of solar radiation can be observed, which can be 2,000 degrees Celsius which is really hot. It's even hotter than Venus. The temperature of the thermosphere is measured by special Instruments.
What is the tropopause?
The tropopause separates the troposphere from the next layer.
How big is the troposphere layer?
The troposphere goes from the Earth's surface to 16 kilometers above. The troposphere is 8km thick near the poles. The troposphere's height is 17km at the equator.
Why is the upper atmosphere colder than the lower atmosphere?
The upper atmosphere is colder than the lower atmosphere because it is farther away from the Earth's surface. The atmosphere gets most of its heat from the Earth's surface instead of getting it directly from the sun. The sun heats the land and the Earth heats the atmosphere.
How many layers does the Earth's atmosphere have and what are they?
There are five layers. They are called the troposphere, stratosphere, the mesosphere, the thermosphere and the exosphere.
What do the gases do?
These gases protect us from bad rays from the sun. The atmosphere protects the Earth and gives materials necessary to help support life on Earth like oxygen and water.
Where is the troposphere and what happens there?
Troposphere is the lowest layer to the Earth. A lot of the different kinds of weathers occur in this layer.
How does the mesosphere protect the Earth?
The mesosphere helps protect the Earth from large things in space which are called meteoroids. The meteoroids go in the atmosphere and then they burn up in the mesosphere.
What is the temperature of the troposphere?
A small amount of heat energy is trapped by the atmosphere. The troposphere drops to 6.5 degrees Celsius from every 14 kilometer of the Earth's surface. At 12 kilometers above the Earth's surface the temperature would go to zero.
Why is the sky blue?
Light has different colors based on what the wavelength looks likes. The gases in the atmosphere go all over with different colors of light and will let other different colors pass by. The blue light is the main light because there is a lot of blue light in the atmosphere. The color that mainly passes through the atmosphere is mainly blue.
How are the particles in the exosphere special?
Particles can travel far distances without hitting each other. The air is very thin. The gas molecules can go into space. The particles in the exosphere can travel large distances without hitting other particles.
What is the temperature of the stratosphere?
The temperature would decrease with altitude. The average temperature of the stratosphere is -60 degrees Celsius. The stratosphere's temperature is about 18 degrees Celsius.
How big is the exosphere?
The exosphere goes from 550 kilometers above the Earth's surface to thousands kilometers above the Earth's surface.
How big is the ionosphere?
The ionosphere goes from 80 kilometers above the Earth's surface to 550 kilometers above the Earth's surface.
What is special about the particles in the ionosphere layer?
The ionosphere has a lot of moving particles. The ionosphere absorbs the ultraviolet radiation and the x rays that come from the sun. Big disturbances on the sun's surface can cause the number of ions in the ionosphere to increase. The AM radio waves bounce off of the ionosphere.
What are the two parts of the thermosphere?
The lower part of the thermosphere is called ionosphere. The upper part of the thermosphere is the exosphere.
How big is the mesosphere?
The mesosphere goes from 48 kilometers above the Earth's surface to 80 kilometers above the Earth's surface.
What is the temperature of the mesosphere?
The mesosphere has it's coldest temperature witch is -100 degrees. The mesosphere drops to -100 degrees Celsius. The upper mesosphere is the coldest place in the atmosphere.
What are two things in the stratosphere?
The ozone layer is in the stratosphere, which is a gas that gives UV rays which will protect us from solar radiation. The jet stream are strong winds that move the weather on Earth.
What is the stratopause?
The stratopause separates the stratosphere from the next layer.
How big is the stratosphere?
The stratosphere goes from 16 kilometers above the Earth's surface to 48 kilometers above the Earth's surface. The stratosphere extends from the troposphere up for 50 kilometers. There is an upper and lower stratosphere.
What is the stratosphere layer?
The stratosphere goes from 16 kilometers above the The stratosphere gets heated on the top from the ultraviolet radiation.
