10/10 EARTH SCIENCE EXAM

Question 1

density formula

Answer 1

D=m/v

Question 2

volume formula

Answer 2

V=m/d

Question 3

mass formula

Answer 3

M=v x d

Question 4

what is mass?

Answer 4

the amount of matter contained in a given object, mass is measured in grams (g)

Question 5

what is volume?

Answer 5

the amount of space an object takes up, measured in cubic centimeters (cc) or millimeters (mL)

Question 6

what causes density to change?

Answer 6

density can change if temperature and pressure is affected

Question 7

an increase in temperature causes?

Answer 7

an increase in temperature causes a DECREASE in density

Question 8

an increase in pressure causes?

Answer 8

an increase in pressure causes an INCREASE in density

Question 9

what happens to denser materials?

Answer 9

DENSE materials tend to sink towards the Earth’s core, LESS dense materials tend to sink towards the Earth’s surface

Question 10

what is the MOST dense part of Earth?

Answer 10

EARTH’S INNER CORE

Question 11

what is the LEAST dense part of Earth?

Answer 11

THE OUTER ATMOSPHERE (very light gases there)

Question 12

what way does longitude lines go?

Answer 12

up and down, LONG. they MEASURE distance east to west, but RUN north to south

Question 13

what way does latitude lines go?

Answer 13

sideways, think of a climbing a ladder. they MEASURE distance north to south, but RUN east to west

Question 14

what is the prime meridian?

Answer 14

the prime meridian has a longitude of 0 degrees and runs through Greenwich England. the prime meridian splits the world into the eastern and western hemispheres

Question 15

what is the equator?

Answer 15

the equator splits the northern and southern hemisphere, the equator has a latitude of 0 degrees.

Question 16

what comes first longitude or latitude?

Answer 16

LATITUDE, think of climbing a ladder

Question 17

what is polaris?

Answer 17

polaris is the North Star, polaris sits directly above the north pole. if you see polaris you are closer north

Question 18

contour lines?

Answer 18

an isoline which connects points of equal ELEVATION or altitude, measures steepness

Question 19

isothern?

Answer 19

an isoline which connects points of equal TEMPERATURE

Question 20

isobar?

Answer 20

an isoline which connects points of equal PRESSURE

Question 21

isoseismal line?

Answer 21

an isoline which connects points of equal EARTHQUAKE INTENSITIES

Question 22

gradient?

Answer 22

G= change in field value (cifv) / distance (d)

Question 23

isoline?

Answer 23

lines on maps which are drawn to connect points of equal value

Question 24

topographic map?

Answer 24

a map that displays forms and features of land surfaces

Question 25

what is the equatorial diameter?

Answer 25

the equator

Question 26

what is the polar diameter?

Answer 26

the prime meridian

Question 27

% error equation?

Answer 27

dfav / av x 100

Question 28

why does temperature affect density?

Answer 28

heating a substance causes the molecules to spread further apart, if warmer temperature density is decreased

Question 29

why does pressure affect density?

Answer 29

the object will be compressed, if increase in pressure density is increased
