Physical Science 5 Q

QuestionAnswer
What kind of water makes up the majority of earth’s water supply? Salt water
What is the largest source of freshwater on the planet? Icebergs and Glaciers
What is the largest source of liquid freshwater on the planet? Groundwater
In the hydrologic cycle, name the ways water can enter the atmosphere. Different ways water can enter the atmosphere by precipitation, ground water, river flow, evaporation, and transpiration.
When a raindrop hits the ground, name three ways it can eventually end up in river. 1. The raindrop gets sucked into the ground. 2. The raindrop gets evaporated. 3. The raindrop drops into a river/ocean.
What process in the hydrologic cycle puts soil moisture into the atmosphere? The transpiration in a ground flow gets caught into the river flow.
In which body of water would the residence time be shorter: a quickly moving river or a lake that has no river outlets? A lake that has no river outlets.
What must a lake have in order for it to be a freshwater lake? Rivers and/or streams
Why is the salinity of the ocean evidence that the earth is not billions of years old? The water would be way saltier than it is now.
If you tasted melted sea ice, would it taste like freshwater or saltwater? It would taste like salt water.
Where do icebergs come from? Pieces of ice fall off of larger glaciers and over time they form in the water that process is called calving.
Where do glaciers come from? Glaciers form because of a technique called firn.
What is the term for the process by which a portion of a glacier breaks off and falls into the water? Calving.
The captain of a ship sees an iceberg and steers clear of it. Why is the captain still worried about a collision? The captain is afraid of the iceberg because 90% of it is underwater so the bottom of the boat could scrape up against it.
Suppose you studied tow areas of land close to one another. In the first, a lot of trees. In the second, no trees at all. The two areas seem identical. Which one has the deeper water table? The land that have lots of trees.
If no energy is added to air, what happens to the temperature when the air expands? The temperature will decrease.
Will fog be thicker in a smoky area or an area free of smoke? The fog will be thicker in areas with smoke.
What kind of cooling is responsible for most cloud formation? Adiabatic cooling
A bright student notes that with few modifications, a refrigerator can become a “hot box,” keeping things warm instead of cold. Explain. The refrigerator will pump the cool air out into a warm room that warm air will be replaced with cool air while the refrigerator pumps warm air into itself making it into a “hot box.”
What kind of water pollution is the hardest to track back to its source? Groundwater.
