Water Cycle S.1• Evaporation- occurs when liquid

water from the Earth’s surface & from living organisms changes into water vapor

• Condensation-occurs when water vapor cools & changes into liquid water droplets that form clouds in the atmosphere

• Precipitation- rain, snow, or hail that falls from clouds onto the Earth’s surface

S.1 Vocabulary

• Erosion• Water cycle• Tributary• Drainage basin• Divide• Channel• Load

Deposition in Water S.2

a. Erosion occurs on the outside bank where the water flows faster

b. Deposition occurs along the inside bank where the water flows

c. Delta- usually forms on a flat surface & consists mostly mud

S.2 Vocabulary

• Deposition• Alluvium• Delta

• Alluvial fan• Flood plain

Underground Water S.3• Aquifer- a rock layer that stores and allows the

flow of ground water• Spring- if the water table reaches the Earth’s

surface, water will flow out the ground• Artesian Springs- springs that form where cracks

occur naturally in the cap rock and the pressurized water in the aquifer flows through the cracks to the surface

• Wells-a human-made hole that is deeper than the level of the water table

S.3 Vocabulary

• Ground water• Water table• Aquifer• Porosity• Permeability• Recharge zone• Artesian spring

Water Pollution S.4

• Surface water, such as rivers and lakes, and ground water are often polluted by waste from cities.

• Point-source pollution and nonpoint-source pollution

• Sewers and oil polluted our water

S.4 Vocabulary
