Atmosphere 1

Question 1

The process of photosynthesis was important to the evolution of our atmosphere because it

Answer 1

removes some carbon dioxide from the atmosphere, creates oxygen gas that formed the ozone layer, releases free oxygen into the atmosphere which could be used by other organisms

Question 2

In earth’s current atmosphere which gas is the most abundant or is there the most of?

Answer 2

Nitrogen

Question 3

How did the development of oceans affect Earth’s atmosphere & temperature?

Answer 3

Oceans absorbed CO2 from the atmosphere, cooling it down.

Question 4

The order of the layers of Earth’s atmosphere from the BOTTOM (surface) to the TOP are:

Answer 4

Troposphere, Stratosphere, Mesosphere, Thermosphere

Question 5

Stratosphere and Thermosphere have __________ temperature with increasing altitude.

Answer 5

increasing

Question 6

Troposphere and Mesosphere have a _________ temperature with increasing altitude.

Answer 6

decreasing

Question 7

All weather occurs in the

Answer 7

troposphere

Question 8

The ozone layer is found in the

Answer 8

stratosphere

Question 9

What layer is of electrically charged atoms? This is also where the Aurora Borealis occurs.

Answer 9

Ionosphere

Question 10

Electromagnetic radiation from highest to lowest by the amount of energy they carry.

Answer 10

Gamma rays, X-rays, ultraviolet, infrared, microwaves, radio waves

Question 11

All of the following are ways that Electromagnetic Radiation can interact with matter in the Earth’s atmosphere EXCEPT

Answer 11

increase the number of protons in an atom

Question 12

What are the special characteristics of Earth’s atmosphere that allow for life?

Answer 12

Earth’s temperature allows for water to be in the liquid form, which is essential for life.
Earth has oxygen gas which allows animals to breathe
Earth has enough carbon dioxide in the atmosphere to keep the temperature warm at night.

Question 13

Consider a planet that has an atmosphere similar to Earth’s and is a similar distance from the sun as Earth, but has MORE carbon dioxide in its atmosphere. How would the climate be different than Earth’s?

Answer 13

It will be warmer

Question 14

The presence of ozone in an atmosphere absorbs ________________. The presence of CO2 in an atmosphere traps re-radiated _________________.

Answer 14

higher energy (ultraviolet) radiation; lower energy (infrared) radiation

Question 15

Consider a planet that has an atmosphere similar to Earth’s and is a similar distance from the sun as Earth, but has MORE ozone in its atmosphere. How would the temperature near the surface of the planet be different than Earth’s?

Answer 15

It will be colder

Question 16

Atmospheric pressure is

Answer 16

the force exerted on the surface of the Earth by the air molecules above it.

Question 17

Order of earth’s formation:

Answer 17

1) atmosphere is He and H
2) Bolides collide with Earth and import gasses
3) H and He are boiled off by the sun
4) O2 dissociates and forms ozone (o3) protecting living things
5) as the Earth cooled, water vapor condensed and oceans formed
6) organisms produce o2 into the atmosphere
7) The # of plants and other organisms started to expand creating more o2 gas. Atmosphere is primarily nitrogen and O2 along with other trace gasses such as CO2 and water vapor.
