What is the process of water vapor becoming a liquid Bill Nye?
When water vapor cools enough to become a liquid, we say it “condenses”. Condensation happens when water vapor cools into tiny droplets to make clouds. Precipitation is when water from the clouds falls to Earth as rain, sleet, hail, or snow.
What does a river do to the land it flows through?
Streams and rivers erode and transport sediment. They erode bedrock and/or sediment in some locations and deposit sediment in other areas. Moving water, in river and streams, is one of the principal agents in eroding bedrock and sediment and in shaping landforms.

What is the big deal with the science of water?
Water can dissolve more substances than any other liquid, making it an important way of transporting chemicals, minerals and nutrients from one place to another. Of all the water on Earth, only 3/10s of a percent is usable to human beings.
What is the scientific term for the water cycle?
Earth’s water is always in movement, and the natural water cycle, also known as the hydrologic cycle, describes the continuous movement of water on, above, and below the surface of the Earth.
How do wetlands soak up floods?
Flood Protection Wetlands function as natural sponges that trap and slowly release surface water, rain, snowmelt, groundwater and flood waters. Trees, root mats and other wetland vegetation also slow the speed of flood waters and distribute them more slowly over the floodplain.
What is it called when water vapor turns into a cloud?
Condensation is the process of water vapor turning back into liquid water, with the best example being those big, fluffy clouds floating over your head. And when the water droplets in clouds combine, they become heavy enough to form raindrops to rain down onto your head.
What makes water change from a liquid to a vapor?
When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it evaporates and becomes a gas—water vapor.
What force causes water to flow through a watershed?
Gravity causes precipitation to fall from clouds and water to flow downward on the land through watersheds. Energy from the sun and the force of gravity drive the continual cycling of water among these reservoirs. As the water is heated, it changes state from a liquid to a gas. This process is called evaporation.
How is watershed related to a river system?
A watershed is an entire river system—an area drained by a river and its tributaries. It is sometimes called a drainage basin. Watersheds can cover wide areas. Runoff water from a large watershed in the midcontinental United States drains into the Gulf of Mexico through the Mississippi River system.
Why are rivers not straight?
Rivers meander because any small bend in a river tends to grow. Water flowing around a bend in a river is a little like a car speeding around a bend in a road. The water is thrown toward the outside of the turn. That fast-moving water erodes the riverbank on the outside of the bend.
What causes a river to become more shallow and wider as it goes downstream?
Both width and depth increase downstream because discharge increases downstream. As discharge increases the cross sectional shape will change, with the stream becoming deeper and wider.
Why is evaporated water so clean?
During the process of evaporation, impurities in the water are left behind. As a result, the water that goes into the atmosphere is cleaner than it was on Earth.
What is water science called?
Introduction. Hydrology is the study of water.
