Hydrology

Question 0

Define nonpoint-source pollution

Answer 0

Examples include: Land runoff, rainfall, deposition, and drainage. It’s the non-direct form of pollution and is carried through the water cycle

Any body of rock through which water can flow and can store enough water for domestic and industrial use

Question 4

Define porosity

Answer 4

The total volume of the open spaces or pores in a rock

Question 5

Define well sorted

Answer 5

When all the particles in a sediment are about the same size

Question 6

Define permeability

Answer 6

The ease with which water can pass through a rock or sediment

Question 7

Define zone of saturation

Answer 7

The underground layer of rock where all of the open spaces are filled with water

Question 8

Define water table

Answer 8

The upper surface of the zone of saturation

Question 9

Define spring

Answer 9

A natural flow of groundwater that has reached the surface

Question 10

Define chemical weathering

Answer 10

Rock is broken down due to chemical reaction

Question 11

Explain a young river

Answer 11

Has the fastest velocity, v-shaped, narrow or straight, has rapids, and has lots of erosion.

Question 12

Explain a mature river

Answer 12

Fast to medium velocity, u-shaped, less erosion then a young river, smooth riverbed, slower than young.

Explain an old river

Answer 13

Slowest velocity, u-shaped with meanders and oxbow lakes, little erosion.

Question 14

Define cave

Answer 14

Large underground cave due to carbonization of limestone
