1

Climate

Temperature change over longer longer extended periods of time

2

Major characteristics of weather and climate

Precipitation and temperature

3

Name a few factors that can affect temperature

Latitude, cloud cover, proximity to water, elevation

4

Describe the latitudinal belts and their temperatures.

Low: Warmest
High: Coldest
Middle: Most susceptible to change

5

Convection Air Warming

Air circulates and rises when heated

6

Frontal Lifting

Air currents will become warmer after being affected by a front. Cold fronts produce heavier weather, whereas it is the opposite for the warm

7

Orographic Warming

Air currents will collide with a topographic barrier, warming the air as it happens. Normally, the two sides of the barrier will be polar opposites in temperature

8

How old is Earth?

4.6 Billion years old

9

How long ago was the Permian continent?

225 Million years ago (Pangea)

10

How long ago was the Triassic period?

200 Million years ago (Laurasia and Gondwanaland)

11

How long ago was the Jurassic period?

135 million years ago

12

How many years ago was the Cretaceous era?

65 Million

13

Who founded the idea of tectonic plates?

Alfred Wegener in 1912

14

Describe the Mid-Atlantic Ridges

Undersea mountain ranges that help attribute to the sea floor spreading theory

15

Describe the Sea Floor Spreading Theory

Ocean floors are continuously moving apart from the center and sinking at the edges while new matter generates

16

How thick are tectonic plates?

Approximately 50 miles

17

How slow do tectonic plates move?

1-2 inches per year

18

What moves the tectonic plates?

Radioactivity and heat from the mantle of the earth

19

Describe divergent boundaries

Plates are being pulled apart, left and right in opposite directions

20

Convergent boundaries

Two plates push together. The weaker submissive rock goes underneath the dominant rock. Sometimes, the rock moves upwards, in the case of the Himalayas

21

Convergent boundaries

Two plates rub up against one another. An example would be the San Andreas fault

22

Describe the Ring of Fire

Travels around the tectonic plate boundaries. Volcanic activity is prominent here.

23

Define region

Regions are man made boundaries marked by providences.

24

Lines on a grid system:

Man made invention. Points are ordered in latitude then longitude.

25

Latitude

Categorized in parallels north and south of the equator. 0, 20, 40, 60, 80, and 90.

26

How to determine latitude:

Degrees from the North Star to the horizon

27

Prime Meridian

The zero of longitude.

28

The meridian opposite of the Greenwich meridian is

The international date line

29

Tropics of Cancer and Capricorn

Northern and southern most parallels where the sun is still shining.

30

Map

Flat generalized view of an area, seen from above, reduced in size.
