How many degrees east longitude and how many degrees west longitude?

180 degrees and 180 degrees

the maximum longitude is half the distance around Earth, or?

180 degrees east or west.

how many time zones does Earth have?

24 time zones

Earth is a sphere, which can be divided into how many degrees?

360 degrees

Each degree of latitude or longitude is divided into? which is further divided into?

60 minutes, 60 seconds

the North pole is located at ?

90 degrees north latitude (90 N)

The maximum latitude is one-fourth of he distance around Earth, or?

90 degrees north or south.

the South Pole is located at?

90 degrees south latitude (90 S)

which circle is the largest parallel circle?

Equator

what is used to find locations on Earth's surface?

Imaginary grid system

to describe a location, which do you state first longitude or latitude?

Latitude

map legend

a key that lists all the symbols used on the map- so you can interpret the symbols. It also explains what each symbol means.

profile view

are drawn in cross sections, this view shows a vertical slice through the ground, as though you were looking at Earth's interior form the side. You use these views when study cross sections, or models of the inner structures of Earth.

map scale

determines how large or how small a map might be.

map view or plan view

drawn as if you were looking down on an area from above Earth's surface.

Profile view

is a drawing that shows an object as though you were looking at it from the side

map

is a model of Earth.

conical projections

is formed by placing a light at the center of a globe and projecting the grid pattern on the globe onto a cone wrapped around the globe.

Cylindrical Projections

is formed by placing a light at the center of a globe and projecting the grid pattern on the globe onto a cylinder wrapped around the globe.

time zone

is the area on Earth's surface between two meridians where people use the same time.

Longitude

is the distance in degrees east or west of the prime meridian.

latitude

is the distance in degrees north or south of the equator

map scale

is the relationship between a distance on the map and the actual distance on the ground.

When you cross the International Date Line from West to East. What happens?

it becomes one day later

When you cross the International Date Line from East to West. What happens?

it becomes the day before in the west.

Which lines form complete Parallel circles?

latitude lines

what two features does a map have to help you read and understand the map?

map legend and map scale

latitude

mapmakers also drew lines eat to west around Earth.

longitude

mapmakers started the grid system with a line that circled Earth and passed through the North Pole and the South Pole.

what is the reference or starting point for time zones?

prime meridian

a scale can be written in words, as a?

ratio or a scale bar( fraction)

map

shows the surface of Earth on a flat surface

prime meridian

the 180 degree meridian combine to divide Earth into east and west halves, or hemispheres.

Equator

the center line that divides Earth into the northern hemisphere and the southern hemisphere.

conical projestions

the continents are represented accurately only because the other areas, such as the oceans,are distorted or cut away.

what happens when you cross the International Date Line?

the day changes

International Date Line

the line of longitude 180 degrees east or west of the prime meridian

Equator

the reference line halfway between the North and South Poles

prime meridian

the reference line that passes through Greenwich, England

Cylindrical projections

these maps are accurate in showing shapes near the equator. shapes near the poles look much larger than they actually are.

grid system

this system uses two sets of imaginary lines that encircle Earth. The two sets of lines are called latitude and longitude. The intersection of a line of latitude and a line of longitude can pinpoint a location on a map or a globe.

why were time zones created?

to make travel, communication, and doing business easier for everyone.
