Describe what a watershed is.
The area that supplies water to a river system.
100
Describe the structure of a water molecule.
There is 1 oxygen atom and 2 hydrogen atoms.
100
What do we call the continuous process by which water moves from Earth’s surface to the atmosphere and back?
The Water Cycle
100
What do we call water as a gas?
Water Vapor
200
When molecules that are different attract.
Adhesion
200
What is the area that separates watersheds called? how does this work?
Divides are a high area of raised land (often mountains) that prevent runoff from running into other river systems.
200
What do we call the tightness across the surface of water that is caused by the polar molecules pulling on one another?
Surface Tension
200
What is precipitation? List 3 examples of types of precipitation**DAILY DOUBLE**
Precipitation is water that falls to Earth. Examples are rain, snow, hail or sleet.
200
When energy is released or absorbed that causes a phase change we call this...
Latent Heat
300
The process where water on the Earth's surface enters the soil.
Infiltration
300
What is an aquifer? How are these used by people?
An area that holds groundwater. These are often used for drinking water.
300
What allows water to move against gravity, climbing up a material?
Capillary Action
300
What is the difference between evaporation and transpiration?
Evaporation is the surface of water changing into a gas. Transpiration is water from trees changing into a gas.
300
What is a calorie?
Heat needed to raise a gram of water by 1° C.
400
When opposite ends of a molecule have slightly opposite charges.
Polarity
400
How does runoff get into streams and lakes?**DAILY DOUBLE**
It flows downhill until it falls into the stream or lake.
400
How does the specific heat of water compare to the specific heat of most other substances? **DAILY DOUBLE**
Compared to other substances water takes a large amount of heat to increase its temperature.
400
Explain how and where evaporation takes place.
Evaporation is the process by which molecules at the surface of a liquid absorb enough energy to change to a gas.
400
When a solid goes directly to a gas we call this...
Sublimation
500
The process where plants give off water vapor through their leaves.
Transpiration
500
What are 4 landforms made by groundwater?
Cysers, hot springs, caves, sinkholes, aquifers.
500
Why is water a Universal Solvent?
Water can attract other polar substances such as sugar, bleach or oxygen, in doing so water dissolves these substances.
500
What percent of Earth’s water is found in its oceans?
97%
