6
It is the air that surrounds the earths surface.
7
What is the atmosphere?
8

• It is the part of the biosphere that contains
  earths solid surface and the interior.

9
What is the lithosphere
10
Oxygen (O2) is to atmosphere as H2O is to this
11

• What is the hydrosphere?

12
Life could not survive because Earths atmosphere
was originally this
13
What is toxic?
14

• It is the theory that Earths surface cracked
  into plates millions of years ago and these
  plates have been moving and shifting ever since.

15
What is Plate tectonics?

DAILY DOUBLE
17
It is the organism that is believed to be
responsible for adding oxygen to earths
atmosphere, allowing other life to evolve.
18
What is cyanobacteria?
19
Place the following in order to describe the
creation of earth

• 1.The earth began to cool.
• 2.Energy heated the new planet to high
  temperatures
• 3.Earths molten surface hardened into rock.
• 4.Gas and rocky debris circling the sun crashed
  together.

21
It is the name for the part of the earth north of
the equator.
22
What is the Northern Hemisphere?
23
They are tiny organisms that live in Earths most
harsh or extreme environments
24
What are extremophiles?
25
It is hot and humid on average. This statement
is a description of an areas ________.
26
What is climate?
27
It is to atmosphere what water is to hydrosphere.
28
What is air?
29
Without this part of the biosphere the earths
temperatures would be too hot during the day and
too cold at night to support life.
30
What is the atmosphere?
31
It is found in the stratosphere and gives some
protection from ultraviolet radiation.
32
What is the ozone?
33
It is the major driving force for the temperature
of earth. It also supplies most of the earths
energy.
34
What is the sun?
35
They are the two major climate related factors
that determine where an organism can survive.
36
What are temperature average rainfall?
37
It is the reason that oobleck is used to
demonstrate the earths asthenosphere.
38
What are the properties of solids and liquids?
39
They are the 4 the major driving forces that
affect climate and weather.
40

• What is the sun, air movement, the shape of the
  land and water content.

41
Explain how temperature differences cause air
movement.
42
Warm molecules move faster and spread out
becoming less dense so these molecules rise.
Cold molecules move slower and are located closer
together so the air is more dense and sinks.
