Vocabulary

I. Surface Water Movement

-Water cycle-Figure 9-1 on page 212

a. Runoff-know definition and factors that influence it.

1- Vegetation-allows more water to enter ground

2- Rate of Precipitation-enters ground through infiltration

3- Soil Composition-fine particles vs. coarse particles

4- Slope-steeper

b. Stream Systems-flow of runoff into rills and gullies

c. Watersheds and Divides-definitions

d. Stream Load-materials carried by stream

1- Solution-know definition and makeup

2- Suspension-definition and makeup

3- Bed Load- definition and makeup-Potholes-what causes them

e. Stream Velocity and Carrying Capacity-

- Discharge- know formula-page 218

f. Floodplains- definitions and causes

II. Stream Development-

-stream channel-pathway

-stream banks-confines

-Headward erosion

a. Formation of stream valleys

-example Grand Canyon-stream downcutting

b. Meandering Streams-know figure 9-18 page 225

-deposition and erosion-where they occur

- oxbow lake

c. Deposition of sediment-Alluvial fan-base of mountain and Delta-rivers

d. Rejuvenation- know definition: uplifted or base level lowers

III. Lakes and Wetlands

-know the definition of each and how they are formed

-example: eutrophication-bog-wetland(both fresh and salt water)

Chapter 10

I. Movement/Storage Groundwater

-Hydrosphere

-Precipitation- infiltration

-Groundwater Storage-porosity-subsurface materials

-Zone of saturation- know figure 10-2 page 241

water table-location-varies depending on local conditions

flow depends on slope

-Groundwater movement- permeability-know figure 10-1 pg. 241

Aquifers-permeable layers

II. Groundwater Erosion and Deposition

-Dissolution-chemical equations on page 244-recognize them

-carbonic acid and calcium carbonate-produce ions in groundwater

-Caves-acidic groundwater and limestone

-Karsts topography- sinkhole-development of and features

III. Groundwater Systems-know vocabulary

-Springs-discharge of groundwater

-formation of springs

-Geysers and Hot Springs-Yellowstone Park
