You
the difference in elevation between the highest and lowest point.
relief
The boundary between the land and a lake/ocean is called the:
coastline
photos taken with cameras mounted on airplanes
aerial photography
a long deep valley on the ocean floor:
trench
a landform with high elevation and high relief
mountain
the amount of dissolved salt in a sample of water:
salinity
As you descend into the ocean the temperature ________ and the pressure _________.
decreases, increases
the location where sediments (small particles of soil, rock, debris) pile up at the mouth of a large body of water
delta
help to show us how steep or gradual a slope is:
contour lines
an area that supplies water to a river system:
watershed
The area that stores water and is located below the saturated zone:
aquifer
show us the change in elevation line to line
contour interval
the small amount of rainfall that "runs off" the surface into streams/lakes:
runoff
BIOsphere
(BIO means life)
a hill of sand piled up due to the force of wind
dune
the process of using tools and instruments to determine distances and elevation
surveying
GPS stands for:
Global Positioning System
- uses satellites that orbit the Earth to collect data and create images
Underwater long chains of mountains that are often changing due to actions like volcanic eruptions:
mid ocean ridges
forces that build up the land
constructive forces
the process during which liquid water molecules change into gas (vapor) molecules:
evaporation
the process by which water vapor (gas) is given off through plant leaves, escaping into the atmosphere
transpiration
is the shape of the land and includes traits such as elevation, relief, and landforms
topography
shows surface features as if you are viewing it from directly above and gives us information about elevation, relief, and slope:
topographic map
The Earth gets it energy from:
the sun and heat from the Earth’s interior
means underwater volcano
seamount
