Science Ch.1

Front 1

Irrigation

Back 1

is the process of supplying water to areas of land to make them suitable for growing crops.

Front 2

Photosynthesis

Back 2

the process by which plants use water, plus carbpn dioxide and energy from the sun, to make food.

Front 3

Water vapor

Back 3

the invisable, gaseous form of water.

Front 4

Habitat

Back 4

is the place where it lives and that provides the things it needs to survive.

Front 5

Groundwater

Back 5

water that fills the cracks and spaces in under ground soil and rock.

Front 6

Polar molecule

Back 6

a molecule that has electrically charged areas.

Front 7

Surface tension

Back 7

is the tightness across the surface of water that is caused by the polar molecules pulling on eachother.

Front 8

Capillary action

Back 8

the combined force of attraction among water molecules and with the molecules of surrounding materials.

Front 9

Solution

Back 9

is a mixture that forms when one substance dissolves another.

Front 10

Solvent

Back 10

the substance that does the dissolving.

Front 11

State

Back 11

a form of matter; solid, liquid, and gas.

Front 12

Evaporation

Back 12

is the process by which molecules at the surface of a liquid absorb enough energy to change to the gaseous state.

Front 13

Condensation

Back 13

the process by which a gas changes to a liquid.

Front 14

Specific heat

Back 14

is the amount of heat needed to increase its temperature.

Front 15

Water Cycle

Back 15

is the continuous process by which water moves through the living and nonliving parts of the enviornment.

Front 16

Transpiration

Back 16

eventually the water is given off through the leaves as water vapor in process.

Front 17

Precipitation

Back 17

water that falls to Earth as rain, snow, hail, or sleet.
