Hydrology

QuestionAnswer
In addition to salinity, what factor affects the density of seawater? temperature
Permeable rock layers or sediments that transmit groundwater freely are called? aquifers
What 2 things could happen once water returns to the earth? infiltration and runoff
What causes the movement of surface currents? Wind
Process where a liquid is converted to a gas Evaporation
Oceans are constantly moving due to changes in Salinity and water temperature
Most of the earths fresh water is stored where? Ice caps
What is salinity? the salt content in water
How much of earth's water is in the oceans? 97%
Deep ocean currents move due to changes in density
As you increase in depth in the ocean, what happens to pressure? Pressure increases
As you increase in depth in the ocean, what happens to density? Density increases
Which process brings water from the atmosphere to Earth's surface? Precipitation
How much of Earth's water is fresh water? 3%
What conditions are needed for clouds to form? The warm water vapor needs to meet the cool atmosphere in order for condensation to occur
hot evaporation cool condensation
what drives the water cycle the sun
Why are evaporation rates higher at the equator? The evaporation rates are higher at the equator due to increased direct sunlight at the equator.
What effects the tides? The sun and moon's gravitational pull.
How does deforestation affect the water cycle? Transpiration would decrease.
What percentage earth’s freshwater be found in ice caps, ground, lakes, swamps, and rivers? 3%
A bottle of cold water. the student noticed there is water droplets on the outside of the bottle. Which scientific phenomenon explains the water on the outside of the bottle? Condensation. Hot evaporation, cool condensation.
what can be used to demonstrate the difference between condensation and evaporation? To show condensation, the lab partners must decrease the temperature within the cycle; to show evaporation, they must increase the temperature.
What is the BEST way to improve how we conserve and use water? Monitor water usage and fix leaks.
Aquifer an underground layer of rock or soil that holds water
Continental Shelf A gently sloping, shallow area of the ocean floor that extends outward from the edge of the continent
Continental Shelf An incline leading down from the edge of the continental shelf
Deep Currents Driven by density and temperature gradients. (The E.A.C, dude from Finding Nemo)
Evaporation the process by which molecules at the surface of a liquid, such as water, absorb enough energy to change to a gaseous state, water vapor.
Groundwater water that fills the cracks and pores in underground soil and rock layers
Mid Ocean Ridge the undersea mountain chain where new ocean floor is produced. It is a divergent plate boundary.
Neap tide A tide with the least distance between low and high tide that occurs when the sun and moon pull at right angles to each other.
Precipitation Forms of water such as rain, sleet, snow, hail that fall from clouds when they are too filled with water vapor.
Spring Tide A tide with the greatest difference between high and low tides that occurs when the sun and the moon are aligned in a straight line with Earth.
Tides the steady rise and fall of earth's waters on shores.
Topography the arrangement of the natural and artificial physical features of an area.
Transpiration the process by which plants release water vapor through their leaves.
Trench a deep ocean canyon in the ocean floor. (where all the crabs went)
Water Cycle The continuous process by which water moves from earth's surface to the atmosphere and back, passing through living and nonliving parts of the environment.
