a.

15 feet

b.

45 feet

c.

32 feet

d.

34 feet

Explanation / Answer

QUESTION 1

34 feet

QUESTION 2

south-east

QUESTION 3

13 ft/mile

The lake Magdalene and lake Carroll are around 1 miles away and the surface elevation is 47 and 34 ft respectively. Therefore, the gradient would be, (47-34)/1 = 13 ft/mile

QUESTION 4

limestone

QUESTION 5

carbonic acid (H2CO3)

QUESTION 6

The figure mentioned is the question is not available with the question

QUESTION 7

sandstone

Unconsolidated materials that allow water to move through like sandstone make up the best aquifers as they are permeable and porous.

QUESTION 8

West Lake

The West lake lay at an immediate lower elevation (46ft) from the lake Magdalene and therefore if a colored dye was released into Lake Magdalene, the dye most likely appear next in West Lake.

QUESTION 9

subsidence

QUESTION 10

clay

Lower the particle size, higher is the porosity and therefore, clay has the maximum porosity.

QUESTION 11

volcanoes

QUESTION 12

permeability

QUESTION 13

A stream that receives water from an underground aquifer.

QUESTION 14

Flow lines generally run perpendicular to the water table contour lines.

QUESTION 15

cone of depression

QUESTION 16

ice sheets and glaciers

QUESTION 17

sand
