A judgment based on the results of an experiment.

Organized information used to test a hypothesis.

Used to slow that the results of an experiment is really due to the condition being tested.

Factor that changes in an experiment.

A logicality explanation for events that occur nature.

The factor being measured in an experiment.

a measurement that is factual

a basic unit of volume in the SI units measuring system

a particle of matter

a variable that is held constant in an experiment

a measurement of the force of gravity on the mass of an object

a measurement that is consistent although it may or may not be accurate

a group of objects and the factors that affect the object

a factor that affects an object; examples include mass, temperature, speed, and time.

a variable that is affected by the change to the independent variable. The dependent variable is sometimes called the responding variable

a number that includes a unit

a specific quantity that is counted to make a measurement

a picture that shows how two variables are related

The variable that is changed in an experiment. The independent variable is sometimes called the manipulated variable

the amount of matter that an object contains

the basic unit of mass in the SI Units measuring system; one-thousandth of a liter.

a basic distance unit for the SI Units system of measurement.

a measurement of how much space is occupied by an object

Anything that has mass and takes up space

an uplifting force that acts on an object when it pushes aside an object → Temperature

transfer of heat by direct contact of atoms and molecules → Conduction

a form of energy caused by the motion of atoms → density

stored energy → potential energy

a measure of the speed of an individual atom or of the average speed of a sample containing lots of atoms → Temperature

matter that can flow, usually a liquid or a gas → density

a place where electricity is generated → power plant

the ability to create change in a system → density

an area of land that catches all precipitation and surface runoff and collects it in a body of water such as a river → watershed

the layer of gases that surrounds Earth → percolation

an Earth system that includes all the water on the planet → hydrosphere

the upper level of water underground, below that water table, all spaces are filled with groundwater → water table

water that collects underground → ground water

the process by which a substance in its gaseous phase loses energy and enters the liquid phase; a phase of the water cycle. → condensation

a huge mass of ice that forms on land when snow or ice accumulates faster than they melt → aquifer

An underground area of sediment and rocks that is filled with groundwater. → glaciers

condensed water vapor in the atmosphere falling back to earth in the form of rain, hail, sleet or snow; a phase of the water cycle → transpiration

the process by which plants lose water through tiny pores on their leaves, a phase of the water cycle → evaporation

the process by which a substance in nits liquid phase gains energy and enters the gaseous phase; a phase of the water cycle → evaporation

the process of liquid moving through porous substance → percolation

a set of processes energized by the sun that keep water moving from place to place on earth; also called the hydrologic cycle → water cycle

water that is found on earth's surface in places like oceans, lakes, rivers and reservoirs → surface water

water in gas form → water cycle

water that flows over land until it reaches lakes, rivers, and oceans. → surface runoff

Evaporation is one of the four processes in the______

___________occurs when water goes from gas to liquid

What layer of Earth’s atmosphere is our ozone layer in?

Weather on Earth occurs in what layer of atmosphere?

a layer of atmosphere that occurs from about 11 kilometers to 50 kilometers above earth's surface; the location of the ozone layer

the mixture of gases that make up Earth's atmosphere

the region of the atmosphere that begins at about 500 kilometer and extends into space; the location of the orbits of satellites

the amount of energy needed to raise the temperature of 1 gram of substance by 1 degree celsius.

a layer of the atmosphere that occurs from about 50 kilometers to 80 kilometers above earth's surface; the coldest layer.

a measure of the distance an object is above sea level; usually the object is airborne.

the motion of earth spinning on its axis, the rotation equals one day.

an instrument that measures atmospheric pressure

portions of the atmosphere in the region of the thermosphere where electricity can be transmitted

the motion of earth moving around the sun; one revolution is called a year.

a measure of the force per unit area of air molecules in the atmosphere at a given altitude

a layer of atmosphere that occurs from 0 to about 11 kilometers above Earth's surface; where all weather occurs

a layer of atmosphere that occurs from 80 kilometers to about 500 kilometers; this layer has a low density of air molecules and a very high temperature

a blanket of gases that surrounds a planet

occurs when a cold air mass replaces a warm air mass.

When warm air moves in and replaces cold air it is called a(n)

are characterized by grasses and a dry climate

Which biome is the coldest

Which Biome is the largest land Biome

climate regions with too little rainfall to support a forest. grasslands have grasses as the main vegetation → grasslands

a system of rotating winds around of a low pressure center; a tornado is smaller than a hurricane, but has faster winds → climate
