It is the study of Earth and the universe around it.
Earth science
All the water on Earth
Hydrosphere
Lines on a map running parallel to the equator
latitude.
Detailed maps show changes in elevation of Earth's surface
Topographic Maps
The process of gathering data about Earth
Remote Sensing
Earth's composition and rocks.
Geology
permanently frozen water on Earth.
Cryosphere
Imaginary line divides Earth into two equal parts
a) The Eastern hemisphere
b) The Western hemisphere
meridians.
lines connect points of equal elevation
contour lines
Study pollution, movements of Earth's plates, and melting of glaciers
Landsat satellites
Study weather over a long period of time and chemistry of atmosphere
Meteorology
layers of Earth.
Geosphere
• Used in navigation
Mercator projection
The difference in elevation between contour lines
contour interval
Satellites use radar to map sea surface height
OSTM/Jason Satellites
The study of objects beyond Earth's atmosphere.
Astronomy
All organisms on Earth and the environments in which they live.
Biosphere
best suited for mapping small areas
Conic projection
lines pointing down into the hole
Depression contour lines
map ocean-floor, relies on sonar.
Sea Beam technology
Study remains of organisms and fossils.
Paleontology
blanket of gases that surrounds our planet
Atmosphere.
Keep the planet at a temperature suitable for life
Atmosphere
Maps used to show the distribution, arrangement, and type of rocks located below the soil
Geologic Maps
The satellites are constantly orbiting Earth so that signals from at least three or four satellites can be picked up
GPS
