Flashcard Content Overview

The water cycle is the process by which water moves from place to place above, below, and on the Earth's surface. Water moves around the Earth to different places and also through living organisms. Water is a scarce natural resource because the total amount of water is relatively constant and doesn't change.

The three main parts of the water cycle are precipitation, evaporation, and condensation. Water can exist as one of three states of matter - solid, liquid, or gas - depending on temperature and pressure.

Two-thirds (2/3)
Three states of matter that water can exist as
Solid (ice), liquid (water), and gas (vapor)
Surface water
The source of 90% of the water vapor in the air comes from this
The amount of cloud particles needed to form one raindrop
Millions of cloud particles
Forms of precipitation
Rain, sleet, snow, hail, and freezing rain
Water vapor
Gaseous state of water that is always present in the atmosphere, even on a cloudless, sunny day
Cloud formation
Occurs when water vapor forms around small particles, like bits of dust in the air
Gravity
The force that causes the cloud particles to fall and be pulled to Earth as precipitation
What USGS stands for
