The hydrosphere is defined as which of the following?
erosion
Air, water or ice moving away pieces of rock
plate boundary
area where tectonic plates meet and volcanoes and earthquakes tend to be found
climate
average weather for a particular region
fault
break in the Earth's crust where sections of rock move past each other
chemical weathering
breaking down rock and changing it into a new substances
physical weathering
breaking down rock without changing it into new substances
weathering
breaking rock into smaller pieces
mantle
largest layer of the Earth that is semi solid/liquid
outer core
liquid layer that is the second layer to the center
tectonic plates
massive, irregularly shaped rocks that slowly drift on Earth's mantle.
water cycle
movement of Earth's water through evaporation, condensation and precipitation.
mineral
naturally forming solid with a specific composition that forms crstals
sediments
pieces of rock
air pressure
pressure of the air caused by the weight of the atmosphere
metamorphic rock
rock formed from heat and pressure changing the composition of rocks
sedimentary rock
rock formed from pieces of rocks and remains of living things cemented together
igeneous rock
rock formed when melted rock cools and hardens often near a volcano
humidity
the amount of water vapor in the air
tilted axis
the cause of the seasons on Earth
phases
the changing appearance of the moon as the moon revolves around the Earth
weather
the day to day state of the atmosphere
waning
the moon phases when we see less and less of the bright side of the moon
waxing
the moon phases when we see more and more of the bright side of the moon
fossil
the remains or impression of a prehistoric organism
crust
the thin outer layer of the Earth
cold front
transition zone where a cold air mass replaces a warm air mass
warm front
transition zone where a warm air mass replaces a cold air mass
inner core
very dense solid layer in the center of the Earth
magma
what the mantle is made of
rotation
when an object spins in a circle
revolution
when an object travels in a circle around another object
evaporation
when water changes from a liquid to water vapor and rises into the atmosphere
condensation
when water changes from water vapor to liquid water in clouds
precipitation
when water falls to the ground as rain, snow, sleet or hail
runoff
when water flows over the surface to rivers, lakes and ultimately oceans
stationary front
zone where a warm or cold front stops moving
