Answer 4

top of the aquifer (shifts with seasons and usage from people’s wells)

Question 5

infiltration

Answer 5

water soaking into ground

Question 6

permeability

Answer 6

ability for water to infiltrate

Question 7

porosity

Answer 7

amount of pore space between grains and soil particles

drainage basin/water shed

Answer 9

a river system and all of the area where it travels and drains

Question 10

delta

Answer 10

big deposit of sediment where river enters ocean or big lake

Question 12

meander

Answer 12

bend in a river

Question 13

outside of meander

Answer 13

fast = erosion

Question 14

inside of meander

Answer 14

slow = deposition

Question 15

dendritic drainage pattern

Answer 15

looks like a tree pattern from above; forms over horizontal sed. rocks

Question 16

rectangular drainage pattern

Answer 16

looks like long, parallel lines with smaller lines perpendicular to the bigger lines; forms over faults and folds

Question 17

radial drainage patter

Answer 17

looks like rays from the Sun (in kid’s pictures); forms on peaks or volcanoes where rivers radiate from central high point

Question 18

annular drainage pattern

Answer 18

looks kind of circular from above like the rivers are flowing around something; forms where rivers cut through softer rocks that surround a harder, igeneous dome

Question 19

levee

Answer 19

human-made structure designed to protect an urban floodplain from a river’s floods (keep the river in the channel)

Question 20

discharge

Answer 20

the amount of water and sediment in a stream

Question 21

runoff

Answer 21

water that doesn’t infiltrate and runs over the landscape instead
