What role does the atmosphere play in weather?

The atmosphere is a crucial part of the water cycle. It is an important reservoir for water, and the source of precipitation. The atmosphere moderates Earth’s temperature. Weather takes place in the atmosphere.

How does the atmosphere regulate weather and climate?

The atmosphere regulates the Earth’s temperature and protects living things from the Sun’s most harmful rays. All weather takes place in the atmosphere, most of it in the lower atmosphere.

How does the atmosphere help Earth’s temperature?

Along with the oceans, the atmosphere keeps Earth’s temperatures within an acceptable range. Greenhouse gases trap heat in the atmosphere so they help to moderate global temperatures. Without an atmosphere with greenhouse gases, Earth’s temperatures would be frigid at night and scorching during the day.

Why is the atmosphere essential for the life?

Answer: Atmosphere is very important for sustaining life: It contains various gases like O2, CO2, N2 which are required for various life processes by plants and animals. (ii) gas is used by plants to prepare food by the process called photosynthesis (iii) Oxygen is required for burning, combustion and respiration.

What are the features of atmosphere?

Earth’s atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

How thick is the atmosphere of Earth?

about 60 miles

Can we leave Earth’s atmosphere?

Any spacecraft traveling through it wouldn’t notice a thing or be slowed by drag. It does mean, however, that humankind has yet to leave the Earth’s atmosphere. The moon, the farthest point ever reached by astronauts, orbits well within the geocorona. All of this challenges the way we see our planet’s borders.

Why is it hard to enter the atmosphere?

It is heavy when it takes off, but during the landing, having used up most of its fuel, it is low density and so slows down much higher in the atmosphere than the Space Shuttle. As a result, it will reach lower temperatures than the Space Shuttle on re-entry though higher than a supersonic jet at Mach 3.

What does Earth reentry feel like?

Even after a ten-to-fourteen-day mission to space, the return is dramatic. Your balance system is turned upside down, and you feel very dizzy. When you stand up for the first time, you feel about five times heavier than you expect. All of this can be unsettling, and nausea is not unusual.

How does Dragon return to Earth?

The Astronauts Crew Dragon autonomously undocks from the Space Station and performs a series of departure burns to move away from the orbiting laboratory. Dragon experiences significant heating and drag as it re-enters Earth’s atmosphere, which slows the velocity to the point of safe parachute deploy.

How long does it take to enter the atmosphere?

Space is at the end of Earth’s atmosphere, about 62 miles upwards. This is called the Karman Line and means you’ve gone past the Thermosphere and are now into the Exosphere. NASA launch director Mike Leinbach said: “It takes the shuttle approximately 8-1/2 minutes to get to orbit.

How do astronauts survive re-entry?

The heat is so great during re-entry that a special thermal protection system is used to keep the spacecraft intact. On the Shuttle, special silicon tiles are placed on the aluminum skin to insulate the skin. On the leading edge of the wings, carbon-cabon composite material is used to withstand the heat.

What happens if the spaceship re enters at the wrong angle?

If the angle is too steep, the spacecraft burns up, and anyone unlucky enough to be inside is crushed. If the angle is too shallow, on the other hand, the spacecraft skims off the edge of the atmosphere like a stone skimming along the surface of a pond. The angle of re-entry for the space shuttle was 40 degrees.
