w-e-d and topo maps

Question 1

mechanical

Answer 1

rocks are broken apart by physical processes

Question 2

chemical

Answer 2

Chemical reactions to solve the rock or change them into different minerals

Question 3

oxidation

Answer 3

• acid rain

* plant acid

Question 4

erosion by water

Answer 4

Stream erosion
rain drops
wave erosion

Question 5

erosion by wind

Answer 5

The cause is by the wind

Question 6

erosion by glaciers

Answer 6

breaks off pieces of rock as it moves over it

Question 7

glaciers

Answer 7

glaciers are large sheets of ice that forms as show is compacted over time

Question 8

erosion by gravity

Answer 8

movement of sediment or rock downslope due to pull of gravity

Question 9

deposition

Answer 9

The laying down of sediment that has been eroded

Question 10

topographic map

Answer 10

A topographic map is a two dimensional model of the earths surface it is also known as a Contor map

Question 11

contour line

Answer 11

contour line connects points of equal elevation

can also show a depression, crater, or sink hole on a map — shown by dashed Lina on the in side of a contour line

Question 12

elevation

Answer 12

they show the elevation and shape of the land

Question 13

relief

Answer 13

relief is the difference between high and low elevations

Question 14

contour interval

Answer 14

The contour interval is the difference in elevation between each line the difference must be the same in all lines

Question 15

index contour

Answer 15

usually every fifth line is printed darker and has an elevation printed on it

Question 16

rules for contours

Answer 16

contour lines never cross

contours from closed loop even if not shown on the map

contours bend upstream when crossing a stream

The maximum possible elevation for uphill is one less then what then next Contor should be

Question 17

steeper slope

Answer 17

contour lines are closer together

Question 18

weathering

Answer 18

processes that works to breakdown rocks

Question 19

gradual/gental slope

Answer 19

contour lines are farther apart

Question 20

benchmark

Answer 20

a location whose exact elevation is known and is noted on a brass or aluminum plate. Benchmarks are shown on a map by an x with the letter BM written next to them.

Question 21

map scale

Answer 21

indicates the distance on the map compared to the in the real world

1. ) could be numerical
2. ) or graphical

Question 22

upstream

Answer 22

going against the flow of water ; going against the direction of the H2O is flowing from

Question 23

deltas and alluvial fans

Answer 23

a fan shaped deposits at the mouths (ends) of the stream

Question 24

flood plain

Answer 24

level strips of land on the sides of a rivers that are made of sediment that are deposited during flood

Question 25

meanders

Answer 25

bend in a river

Question 26

oxbow lake

Answer 26

meander that gets cut off form the river
