example of condensation
Dew on grass or water on an ice glass
The gulf stream originates in the ——— amd travels up the East Coast of the US before combining with the____
Gulf of Mexico/north Atlantic drift
A powerful warm, swift ocean current flowing in the Atlantic is called the
Gulf stream
The oceans help distribute __ around the globe
Heat
Wells
Holes dug or drilled deep into the ground to reach a reservoir of groundwater
The ocean water is made up of ___ and ____. The other two main elements are ___ and _____
Hydrogen/ oxygen and chlorine/ sodium
After hydrogen, oxygen, chlorine and sodium, the next most abundant elements in ocean water is....
Magnesium, sulfur and calcium
Without currents, regional temperatures would be ———- which would make it super hot at the equator and frigid at the polls
More extreme
Hydrosphere
all the waters on the earth's surface, such as oceans, lakes, ground water, glaciers, water vapor, precipitation, and even clouds!
Surface Ocean Currents
caused by global winds pushing along the surface of the ocean
Earth's Spheres
hydrosphere, atmosphere, biosphere, geosphere(lithosphere)
Rivers
large streams that carry water from the mountains to the sea
Aquifers
porous, water-holding UNDERGROUND ROCKS that provide millions of wells with steady flows of water.
Biosphere
the part of Earth where life exist such as grass lands deer plants animals bacteria fungi bugs s
Surface ocean currents are driven primarily by ________ and modified by ________.
the wind and the Coriolis effect.
Ground water
underground water that is held in the soil and in pervious rocks
—- of the planet is covered by oceans
70%
Earths freshwater is divided into what percentages
70% frozen, 29% ground water, less than 1% lake and rivers
What percentage of earths water is saltwater
97%
____ of the water on earth is in the oceans
97%
During water cycle the amount of water
Stays the same
____ is fresh water in lakes rivers and aquifers
1%
___is locked in glaciers and ice caps
2%
What percentage of earths water is freshwater
3%
atmosphere
A thin layer of gases surrounding Earth that contains gases, clouds, wind, oxygen, nitrogen, carbon dioxide
Gulf Stream
A warm ocean current that flows from the Gulf of Mexico northward through the Atlantic Ocean
Much of the suns radiation is __ in the oceans, in the form of ___, particularly at the equator
Absorbed/heat
Watershed
An ecosystem where all water runoff drains into a single body of water
Coriolis effect
Causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to Earth's hemisphere.
Water droplets stick together due to
Cohesion
Water vapor meets cold air in the atmosphere and turns into liquid water
Condensation
Because the earth rotates on its axis, circulating air is deflected toward the right in the northern hemisphere and left in the southern hemisphere.... this is called the
Coriolis Effect
Oceans are home to a ——— of life

Warm water is transported from the ——-towards the ——-
Equator/poles
Some of the oceans heat ——- into the atmosphere and some ——- in the oceans
Evaporates/remains
Most of earths freash water is
Glaciers
Ocean currents help regulate ——-even if an area is hundreds of miles from the coast
Global climate
Power sources are
Sun and gravity
Examples of reservoirs
Oceans, glaciers, lakes, ponds, rivers, underground, atmosphere
Name the five oceans from largest to smallest
Pacific Atlantic indian southern artic
Coldwater is transported from the ____ towards the ____
Poles/equator
These are collections of freshwater in low lying areas
Ponds and lakes
Holding or storage place for water
Reservoir
This is flowing freshwater that goes to lakes or oceans. They are fed by smaller ponds or creeks
Rivers
This is a continuous flow of water in a particular direction created mainly by surface winds
Surface ocean currents
Geosphere or lithosphere
The crust and upper mantle of the earth's soil for example canyons, volcanoes, soil, rocks, land forms, mountains, sand, magma
What brings much milder temperatures to western and northern Europe then would otherwise occur
The ocean current called the gulf stream
Divides
The ridges or elevated regions that separate watersheds
Energy that powers the water cycle comes from
The sun
Surface ocean currents are moved primarily by
Wind patterns
The process by which water moves from earths surface to the atmosphere and back again
The water cycle
Which is not a significant use forAquifers—-
To refill lakes and streams
Without ocean currents climate regulation,much more of the land would be
Unusable
What is considered a universal solvent
Water
What supplies water to river systems
Watershed
Surface ocean currents Drive
Weather patterns
Sun heats bodies of water until molecules game enough energy to become a gas
What happens during evaporation
Plants give off water vapor through their leaves to control their temperature
What happens during transpiration
Water and ice droplets become dancer and gravity pulls them back to Earth
What happens in precipitation
Water from precipitation drains downhill into bodies of water
What is runoff
