Topography, Soil, Weathering & Erosion

What does a topographical map show? 

• Shows the water features of an area
• Shows the elevation, slope and relief of a land
• Shows roads and highways
• Shows the population of an area

What does it look like on a topographical map if there is a steep incline? 

• lines are closely spaced
• lines are widely spaced
• lines are curvy
• lines are bolded

What does it look like on a topographical map if there is a valley? 

• V-shaped downhill
• Open circle
• V- shaped uphill
• Widely spaced lines

What does V-lines pointing downhill represent on a topographical map? 

• rivers
• valleys
• mountains
• ridge

What is a contour interval on a topographic map?

• the change in elevation from one line to another
• the amount of space it takes to climb the mountain
• the shape of the land
• how long it takes to walk the land

What are three types of mechanical weathering?

• acid rain, plant growth, oxygen
• carbonic acid, living organisms, water
• animal action, plant growth, release of pressure
• er

What does it mean if something is permeable?

• a material that allows water to seep through it
• a material that is shiny
• a material that allows light to shine through it

What is soil conservation?

• the wearing away of rock and soil
• the management of soil to limit its destruction

What are ways farmers can conserve soil?

• contour plowing
• crop rotation
• conservation plowing
• all of the above

What is stream bank erosion?

• the wearing away of topsoil by water or wind
• the wearing away of soil on banks due to movement of water
• landslides and mudflows
