UNIT 1 TEST1SEASONS & THE WATER CYCLE

Quarter 1: 2013 Test Review

Beginning with fall, the order of the seasons is

•Fall•Winter•Spring•Summer

What is the measurement of the tilt of the Earth on its axis?

23.5

During evaporation, the following change occurs:

Liquid changes to gasWater changes to water vapor

Weather is caused by

The uneven heating and cooling of the Earth.

Which of the steps in the water cycle requires heat from the sun?

Evaporation

What day is the summer solstice?

June 21

Name all 3 of Earth’s climate zones.

Tropical zoneTemperate zonePolar zone

 

How long does it take for the Earth to complete a rotation?

24 hours

What is the Water cycle’s effect on the Earth?

It recycles our water supply so that it is never used up.

The ‘buddies’ in the water cycle are

Transpiration & evaporation

During evaporation, the following change occurs:

Liquid changes to gas

Water changes to water vapor

Why does water vapor rise into the air?

It is lighter than the air.

Clouds are formed by

Condensation

Which climate zone experiences one long warm

and sunny season?

Tropical zone

Why does precipitation occur?

The water droplets in the clouds join together and because of their size and weight.

NAME THAT CLOUD!!!

Often block out the sun, and usually produce light to heavy continuous rain.

Stratus

Usually low clouds seen on an overcast day.

Stratus

Clouds usually associated with thunderstorms, and rise high into atmosphere & have an anvil shape.

Cumulo-nimbus

Thin, wispy clouds, typically found at high altitudes.

Cirrus

Generally occur in fair weather and point in the direction of air movement at their elevation.

Cirrus

These are the ‘typical coloring book style’ clouds.

Cumulus

Fog can be considered a low version of this cloud in contact with the ground.

Stratus

Composed of ice crystals that originate from the freezing of super cooled water droplets.

Cirrus

Puffy clouds with distinct edges and usually a noticeable vertical (upward) development.

Cumulus

Vocabulary!!

Axis: The imaginary line that runs through the Earth from the North pole to the South Pole.

Revolution:The movement of the Earth in it’s orbit around the sun. It takes about 365 days, or one year.

Summer Solstice: The day of the year when the Earth receives maximum amounts of daylight. There are more daylight hours on this day than any other day of the year.

EquatorThe imaginary line of latitude that cuts the Earth into two equal hemispheres.

Rotation:The movement of the Earth as it spins on it’s axis. Takes about 24 hours or one day.

Precipitation: The process in the water cycle after

condensation when the liquid water suspended in the atmosphere stick together and become to heavy. When the atmosphere can no longer hold the water it will fall back to the Earth as RAIN, SNOW, SLEET, or, HAIL.

Winter Solstice: The day of the year when the

Earth receives the MINIMUM amount of direct sunlight. This gives us the day with the least amount of daylight hours.

December 21

Run-off: When the ground is too

saturated to hold any more water, the excess water ‘runs-off’ to lower lying areas.

This helps to move ground water through the water cycle.

Evaporation: Process in the water cycle when heat

from the sun heats the surface of Earth’s water and turns it into a gas called water vapor.

Moves water through the water cycle by turning LIQUID water to a GAS.

Water to water vapor Liquid to gas

Fall Equinox: September 21

This day receives equal amount of sunlight hours to darkness.

Water Cycle: The recycling process of Earth’s water resource. Water is changed from a liquid to a gas (water

vapor) through evaporation, transpiration (evaporation from plant leaves)

Then as the water vapor rises (because it is lighter than air) and reaches cooler air, the water vapor is condensed back into a liquid (and clouds are formed). The water will remain suspended in the air until the molecules stick together and become to HEAVY for the atmosphere to hold.

It then fall back to the Earth as precipitation (rain, snow, sleet, or hail).

Condensation: The process in the water cycle where

water vapor cools in the atmosphere and is changed back into it’s liquid form. This is how clouds are formed.

The liquid water remains in the atmosphere as long as the atmosphere can hold it.

Latitude & Longitude The grid system of

imaginary lines running perpendicular to each other.

It purpose is to give a systematic, accurate, and effective means to describe locations on the Earth.

Spring Equinox:March 21

This day of the year has equal amounts of daylight hours to darkness.

Transpiration: The ‘buddy’ to

EVAPORATION in the water cycle.

This is the process of water evaporating through the surface of leaves.
