What is atmosphere question and answer?
➡️ The atmosphere is
the blanket of gases which surrounds Earth
. ➡️ It keeps the climate on Earth moderate compared to that of other planets. ➡️ Without an atmosphere there could be no life on Earth. ➡️ Earth's atmosphere consists of about 78 % nitrogen, 21 % oxygen, 0.9 % argon, and 0.1 % other gases.
What does the atmosphere depend on?
The relative contributions of each process depend on
the wind, temperature, and moisture structure
in the atmosphere immediately above the surface, the intensity of solar insolation, and the physical characteristics of the surface.
What makes the most atmosphere?
Earth's atmosphere is composed of about 78 percent
nitrogen
, 21 percent oxygen, 0.9 percent argon, and 0.1 percent other gases. … The majority of the mass of the entire atmosphere is contained in the troposphere—between approximately 75 and 80 percent.
What is the importance of atmosphere?
Complete Answer: The atmosphere
contains the air that we breathe
; protects us from the harmful radiation of the Sun; helps to keep the planet's heat on the surface, and plays a very important role in the water cycle.
What is structure of atmosphere?
The atmosphere is comprised of layers based on temperature. These layers are the
troposphere, stratosphere, mesosphere and thermosphere
. A further region at about 500 km above the Earth's surface is called the exosphere.
What is interesting about the atmosphere?
The atmosphere is a layer of gases most commonly referred to as
air that is retained by the gravity of earth
. The atmosphere surrounds the planet, protecting it by absorbing the ultraviolet radiation from the sun, and regulating the temperature extremes that would otherwise occur between day and night.
What is the hottest layer of the atmosphere?
The thermosphere
is often considered the “hot layer” because it contains the warmest temperatures in the atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Temperatures can reach as high as 2000 K or 1727 oC in this layer (Wallace and Hobbs 24).
What is the coldest layer of the atmosphere?
Mesosphere
, coldest layer of Earth's atmosphere.
How does rain affect the atmosphere?
As a raindrop falls through the atmosphere, it
can attract tens to hundreds of tiny aerosol particles to its surface before hitting
the ground. The process by which droplets and aerosols attract is coagulation, a natural phenomenon that can act to clear the air of pollutants like soot, sulfates, and organic particles.
What causes moisture in the atmosphere?
When water evaporates
, it rises and disperses into the surrounding air as the gaseous water vapor. Humidity is the presence of water vapor in the atmosphere. The more water evaporates in a given area, the more water vapor rises into the air, and the higher the humidity of that area is.
Why is it called atmosphere?
An atmosphere (from Ancient Greek ἀτμός (atmós) ‘vapour, steam', and σφαῖρα (sphaîra) ‘sphere') is a layer of gas or layers of gases that envelope a planet, and is
held in place by the gravity of the planetary body
.
How does the atmosphere support life?
The atmosphere protects life on earth
by shielding it from incoming ultraviolet (UV) radiation
, keeping the planet warm through insulation, and preventing extremes between day and night temperatures. The sun heats layers of the atmosphere causing it to convect driving air movement and weather patterns around the world.
What are the 5 types of atmosphere?
Earth's atmosphere has five major and several secondary layers. From lowest to highest, the major layers are the
troposphere, stratosphere, mesosphere, thermosphere and exosphere
. Troposphere.
Which has no atmosphere at all?
Short answer:
Mercury
. Long answer: Mercury is the only planet in our Solar System that has no substantial atmosphere. Technically speaking it does have an extremely thin atmosphere but it's so thin that for all practical purposes it might as well be a vacuum.
