2

tilt

to lean or slant in one direction

autumn

season characterized by cooling temperatures and changing leaves

3

Earth revolution

the orbit of the Earth around the sun is called an Earth revolution; appro 365 days

3

equinox

one of two points during the year where the tilt of its axis causes it to be straigh trelative to the sun (Fall & Spring)

4

spring

season characterized by warming temperatures and new growth

6

Geographic information System (GIS)

A system designed to create, store, analyze, and present geographic data.

uses natural light, such as the sun

passive remote sensing

rotate

14

subdivision of the year characterized by changes in temperature, weather, ecology and hours of daylight (caused by difference in insolation)

season

wavelength

length of one wave

16

passive remote sensing

uses natural light, such as the sun

17

axial tilt

the Earth's axis is tilted

19

insolation

a measure of solar radiation energy received on a given surface area; how much sunlights shines on a place

21

a region on Earth thas has a sunifrom standard time

time zone

22

active remote sensing

uses lasers to shine a certain wavelength onto an object

24

solstice

one of the two points throughout the year when the tilt of the Earth's axis reaches it maximum angle to the sun (Summer and Winter)

25

Global Positioning System (GPS)

A network of satellites in orbit around the Earth which allows us to pinpoint any location and define it as a set of coordinates.

26

Earth's rotation

the rotation of the Earth around its axis - once ever 24 hours
