1

Atmosphere

Gases around earth, envelope gasses surrounding earths surface

2

Layers of atmosphere, from lowest to highest

Troposphere, stratosphere, mesosphere, thermosphere

3

Troposphere contains

The air we breathe

4

Which layer of atmosphere do we live in?

Troposphere

5

Troposphere extends up to -

11 miles above earths surface

6

Troposphere is composed of

78% pure nitrogen (Na), 21% O2 (pure oxygen), H2O gas/vapor, CO2 gas, H4 gas (methane)

7

What's the densest part of atmosphere

Troposphere

8

Atmosphere gets thinner, more - at the bottom

Dense

9

Stratosphere contains

Contains ozone (O3) that filters 95% of the UV radiation from the sun

10

Stratosphere extends

Approx 11 to 31 miles above troposphere

11

Allotrope, example

2 different forms of the same pure substance (element) O2 and O3= allotropes of oxygen

12

Mesosphere extends

Approx 31 to 55 miles above earths surface

13

Thermosphere extends

Extends 55 to 87 miles above earths surface

14

Hydrosphere

(Water sphere), made up of all the water on earth or near earths surface

15

Hydrosphere exists as (3), units?

1. H2O (g) in atmosphere
2. H2O (l) on surface/underground
3. H2O (s) in polar ice, icebergs, glaciers, permafrost

16

Oceans are - percent of earths water

97%

17

Permafrost is frozen solid for - years minimum

2

18

Geosphere

(Land sphere), consists of earths core, mantle, and crust

19

Layers of geosphere, what are they

1. Core:hot center
2. Mantle: Rock
3. Crust: thin outer surface

20

Biosphere

(Life sphere) consists of parts of atmosphere, hydrosphere, and geosphere where life is found

21

Factors sustaining life on earth (life depends on these) (3)

1. High quality energy from the sun
2. Nutrient cycling (Law of Conservation of Mass)
3. Gravity

22

Greenhouse effect

Absorption of infra red radiation by atmospheric gasses and reradiation of energy back toward earth, helps to maintain ideal temperatures

23

Ecology

The study of how organisms interact w/ each other and their environment

24

Cell

Smallest functional unit of life

25

Organism

Individual living thing

26

Population

Group of individuals of the same species living in a particular place

27

Community

Populations of different species living in a particular place

28

Ecosystem

Community of different species interacting with each other and their no living environment

29

Trophic levels

Successive levels of organisms consuming each other, hierarchy of feeding levels

30

Producer also known as

Autotrophs
