In which layer of the atmosphere does most of Earth’s weather occur?

the troposphere, which is the lowest layer

Which explains why air temp near mountaintops are much colder than air temp near sea level?

Air near mountaintops is less dense.

. How is the stratosphere different from the troposphere?

The temp of the stratosphere warms at higher altitude.

When cold air is at the tops of mountains, the air

will flow toward areas of lower pressure in valleys

Answers

1
Which layer of the atmosphere contains the greatest amount of water vapor?
stratosphere
mesosphere
thermosphere
troposphere
2
In which layer of the atmosphere does most of Earth’s weather occur?
the exosphere, which is the outermost layer
the thermosphere, which has the highest temperature
the troposphere, which is the lowest layer
the stratosphere, which contains a sublayer of ozone
3
Which explains why air temp near mountaintops are much colder than air temp near sea level?
No vegetation at sealevel makes the ground absorb more heat
Strong winds near mountaintops decrease temperatures.
Air near mountaintops is less dense.
Large amounts of snowfall decrease the temperature.
4
. How is the stratosphere different from the troposphere?
The composition of the stratosphere lacks ozone
The temp of the stratosphere warms at higher altitude.
The clouds in the stratosphere produce more rain.
The air in the stratosphere has a greater density.
5

oxygen
6
When cold air is at the tops of mountains, the air
is considered to be free of oxygen atoms.
will flow toward areas of lower pressure in valleys
will flow toward areas of higher pressure in valleys.
is considered to be less dense than warmer air.
7

a tendency to lose electrons
a tendency to exist as diatomic molecules
the ability to trap heat
the ability to bond with multiple other elements
8

troposphere
stratosphere
9
The best description of the troposphere is the layer of the atmosphere with the
most ozone.
coldest temperature.
greatest density.
highest altitude
10
The temperature of the stratosphere increases with altitude because of the presence of
carbon monoxide
