Identify the various levels of atmosphere

Biology
2 answers:
faust18 [17]3 years ago
5 0

The<u> troposphere</u> is the lowest layer of our atmosphere.

The next layer up is called the <u>stratosphere. </u>

Above the stratosphere is the <u>mesosphere</u>.

The layer of very rare air above the mesosphere is called the <u>thermosphere.</u>

Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the <u>exosphere </u>to be the actual "final frontier" of Earth's gaseous envelope.

The <u>ionosphere</u> is not a distinct layer like the others mentioned above.

Answer:

The atmosphere refers to the gaseous envelope of earth. It is comprised of various gases with variable composition. The atmosphere of the earth id divided into different layer, namely-

1) Troposphere- It is the layer that is in contact with the surface of the earth. It covers a height up to about 10 km from the ground surface. In this layer, the temperature decreases with the altitude and most of the weather phenomenon takes place here.

2) Stratosphere- This layer extends from 10 to 50 km approximately from the ground surface. in this layer the temperature increases with the altitude. It is due to presence of ozone in this layer that traps the incoming solar radiation.

3) Mesosphere- This layer is above the stratosphere and it extends from about 50 to 80 km above the earth's surface. In this layer, the temperature again decreases with height. here, the temperature drops up to -90°C.

4) Thermosphere- This layer extends from a height of 80 to 500 km approximately above the surface of the earth. In this layer, the temperature again rises with the increasing altitude.

5) Exosphere- This is the extreme outer layer of the atmosphere. It ranges from about 500 to 10,000 km above the earth's surface. The air in this region is comprised of hydrogen and helium.

What does a number in front of a molecular formula stand for?
My name is Ann [436]

Answer:

The small number behind each element symbol designates the number of atoms of each element in a chemical formula. If there is no number, it is assumed there is only one of those elements. A large number in front of a compound designates how many units there are of that compound.

Which best describes what is occurring in this population of squirrels?Number of Squirrels Entering and Leaving a Population aft
wolverine [178]

Answer:

A is the answer. Population growth is decreasing.

Explanation:

The formula is (birth rate + immigration) - (death rate + emigration). So, 4+10=14, 2+3+8+3= 16, 14-16 = -2. -2 is a negative number, meaning population is decreasing. Hope this helped!

Based on the chemical equation, use the drop-down menu to choose the coefficients that will balance the chemical
s2008m [1.1K]

Answer:1Zn+2HCl------1ZnCl2+1H2

Explanation:

A single replacement reaction is one in which a more reactive element displaces a less reactive element from its salt solution.Thus zinc can easily lose electrons as compared to hydrogen and result in the formation of zinc chloride and hydrogen.

According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the mass of products has to be equal to the mass of reactants. The number of atoms of each element has to be same on reactant and product side. Thus chemical equations are balanced.
