Lec 4+5

Question 1

What are the 5 layers of the atmosphere

Answer 1

Exosphere
Thermosphere
Mesosphere
Stratosphere
Troposphere

Question 2

Why are there diff temps with the atmosphere?

Answer 2

Differences in:
Composition
Molecule density
Chemical reactions between molecules

Question 3

Why are there different pressures in the atmosphere layers?

Answer 3

As height increases, there are less total moles of gas exerting force ante the air Belau it.

Question 4

What is the relationship btw pressure and density

Answer 4

Both move in the same direction.a

Question 5

Why does density decrease in atmosphere but increase in underwater conditions?

Answer 5

Due to the # of males ford win a defined medium. Liquids had more moles per unit value than air
Further, gravity holds more air molecules near the surface- same goes for water(more males at the benthic region.) , )

Question 6

Hydrostatic balance

Answer 6

When the net upward pressure is equivalent to the dawn award pressure exerted by gravity
The up~ward force comes from gradients, where molecules move from high concentration to low concentration

Question 7

Troposphere

Answer 7

Where weather occursand most healt energy from sin is absorbed.
Subject to many pressure gradients
Overall height can change depending on season and temp
Commonly 0-10 km

Question 8

Tropopause

Answer 8

Bandry between troop and strato
Beginning stage for small isothermal layer(-57°)
Jet stream location:

Question 9

What is a jet stream

Answer 9

Fast narrow movement of a westerly wind.
They have a large impact on weather.
Commonly @ 10km in l at tropopause.

Question 10

Stratosphere

Answer 10

2nd atmospheric layer
“Temp inversion” region via ozone content
10-50 km

Question 11

How much ozone is in the stratosphere

Answer 11

10ppm- this is aloe compared to the troop sphere that has 0.04 ppm.

Question 12

Why are there minimal clouds in the stratosphere?

Answer 12

Due to low H2O content

Question 13

What is the temp at the stratopause?

Answer 13

• 5°C - this is warmer that tropopause (56°C)

Question 14

How is ozone formed

Answer 14

O2 Absorption of uv light
Overall, it is very unstable

Question 15

How is ozone destroyed) what happens as a consequence?

Answer 15

Breaks via uu light and CFC interactions
When the mole breaks great is released allowing for increased temps in the stratosphere

Question 16

At what elevation is ozone concentration the highest?

Answer 16

Between 20 and 30 km
The max concentration (ppm) is no

Question 17

Mesosphere

Answer 17

Minimal air molecules and uv absorption activity
This is where meteors typically burn via collisions with ions
50-80 km

Question 18

What is the temp at the meso pause?

Answer 18

• 100°C - this is the coldest point due to a lack of radiation molecule reactions

Question 19

Thermosphere

Answer 19

The top atmospheric layer.
Said to have an increase in temp via radiation absorbed by the few molecules present

Question 20

Is there stratification in the thermosphere?

Answer 20

Yes- a predicted theory that molecules with larger malaria mass will exist the bother at portion of the thermosphere while lightermolecules will be found near the top
