You
the force that causes water to flow downhill
gravity
the boundary between land and a body of water:
coastline
Name the Great Lakes and explain how they formed.
Lake Huron, Lake Ontario, Lake Michigan, Lake Erie & Lake Superior (aka- H.O.M.E.S)
These lakes formed within the space where massive ice sheets began to melt at the end of the Ice Age (about 10,000 years ago)
all of the streams and small rivers that feed into a much larger river are known as:
tributaries (they "contribute" to a larger river)
Most of Earth's water is contained in:
our oceans (saltwater)
this sphere is made up of Earth's inner and outer core, mantle and crust (contains landforms such as mountains)
geosphere
shows us how steep or gradual a slope is
contour lines
a group of parts that work together as a whole is known as a:
system
a pile or hill of sand built up due to wind force
dune
the thin layer of gases that help protect & insulate our planet:
atmosphere
What happens to temperature and pressure as someone descends into the ocean?
increased pressure
decreased temperature
refers to the shape of the land:
topography
the stage where water vapor (gas) changes into liquid water droplets
condensation
for any system to fully function, it must have:
energy (the ability to do work)
the change in elevation on a map represented by a number, between each contour line
contour interval
Our Earth system is made up of these 4 spheres:
atmosphere
geosphere
hydrosphere
biosphere
natural forces that build up the land are called:
constructive forces (ex. formation of a mountain)
all living things are part of this sphere:
biosphere
when water vapor (gas) is given off through small openings (stomata) on a plant leaf
transpiration
the height above sea level is known as:
elevation
forms when water slows and sediments (sand/silt/clay) build up
delta
The energy needed for our Earth system to function comes from these two things:
the sun's heat
the Earth's interior heat
Why does ocean water not freeze as fast as freshwater?
The oceans contain salt. The composition of the salt (what it is made up of) causes it to need a colder tempertaure in order to freeze.
Provide an example of a deconstructive force.
floods, fires volcanic eruptions (any wearing away of the land)
long deep valleys that cut into the ocean floor are known as:
trenches
