precipitation
What's a water cycle?
the continual movement of water between the land, ocean, and the air
What's pressure?
the force per unit area exerted on an object
whats water vapor
the gaseous form of water; produced when water evaporates
What does wind mean
the movement of air due to atmospheric pressure differences
What's evaporation?
the process in which matter changes from a liquid to a gas
What's weather?
the properties of the atmosphere at a given time and location, including temperature, air movement and precipitation
What is earth
the third planet from the Sun; the planet on which we live (related words: earthly; earth - meaning soil or dirt)
What's a surface
the top of an object; the outside of an object; the boundary between two objects or material
What is a energy transfer
the transfer of energy from one organism to another through a food chain or web; or the transfer of energy from one object to another, such as heat energy
What is heat?
the transfer of thermal energy
what's a vapor?
water in the gaseous state of matter
What's groundwater?
water stored below Earth's surface in soil and rock layers
What's precipitation?
water that is released from clouds in the sky; includes rain, snow, sleet, hail, and freezing rain
What's buoyancy?
Ability to float
Why is wind energy considered a renewable resource?
It is unlikely that humans will run out of it anytime soon.
What type of energy is torque?
Rotational energy
What's convection?
This process of transferring energy within matter that is moving is called convection.
True or False As precipitation sinks into the ground, the soil moisture and groundwater are renewed.
True
True or False Convection causes warming air to rise.
True
What is a ocean
a large body of salt water that covers most of Earth
What does water mean
a molecule that contains two hydrogen atoms and one oxygen atom; often called "the universal solvent"
What is a cycle
a process that repeats (related word: cyclic)
What's a stream
a small body of flowing water
What are reservoirs?
are storage locations for water. They include oceans, lakes, and rivers. They also include glaciers, soil, rock, living things, and the atmosphere.
