By: Noah Scott & Chase Beasley

What do Hydrologic Cycle Mean?

• Hydro: a combining form meaning “water,”• Logic:the science that investigates the principl

es governing correct or reliable inference.• So it is the science that investigates the

movement of water in the biosphere• Biosphere: the part of our planet where life

resides.

What is the hydrologic Cycle

The four major Parts of the Hydrologic Cycle.

• 1. The sun heats up the Earth and causes Evaporation– Evaporation is the prossess of making liquid into

gas.

Four major parts of the Hydrologic cycle

• 2. Evaporated water are condensed into clouds.– Condensed:to make more dense or compact; redu

ce the volume or extent of; concentrate.

• 3. Water is returned to earth as precipitation(rain,snow,hail)

Four magor parts of the hydrologic Cycle

• 4. The precipition falls back on to earth.• It is taking up by plants roots, Percolates into

the soil to enter into ground water, falls back into rivers ,lakes ect. And starts over from step1

Human Impacts

• Humans Can alter the hydrologic cycle by diverting water for drinking and irrigation.

• Also paving over land surfaces to build homes, and roads impacts the water cycle.

Review questions• 1. What are some human impacts on the Hydrologic

cycle? Explain how it effects it.• 2.Describe the 2nd step of the Hydrologic cycle

include a visual.• 3.Wjat do Hydrologic Mean?• 4. Name 1 abiotic and 1 biotic component that

contributes the hydrologic cycle?• 5. Name 2 reasons why this Cycle is important to life

on earth?• 6.Name 2 places the water go after it has fallen to

earth?
