Hint: Use Legend panel.

Click Map view >> select Historical Map 1689. Let us go to Map View and select Historical Map 1689.
Rotate and point on Historical Map 1689.


Point on continents, latitudes and longitudes.

In this globe we can see,
  • The continents
  • Latitudes and
  • Longitudes
Click on Atlas view.

Point to light green and yellow color.

Point to oceans.

Let us go back to our default view.

We can see that land area is represented by light green and yellow colors.

Water is represented by blue colour.

Click on the drop-down button, next to the Globe View >>Flat View option.

Rotate the globe.


Cursor on South pole.

Let us rotate the globe downward to see the other red dot.

It is the South pole.

Rotate the globe to its default view.

Cursor on the Equator.


Point two equal halves of globe

The yellow horizontal line running around the globe is the Equator.

It divides the earth into two equal parts.

Point on parallel lines on both sides of the Equator. Here we see some lines parallel to the equator.
Point on parallel lines on both sides of the Equator. Since these lines are parallel to theEquator, they are called parallels of latitudes.
Rotate the globe point to horizontal lines on the globe.

Shows parallel lines in the globe.

Notice that some lines are connected from the North Pole to the South Pole.

These lines are Meridians of longitudes.

Point to Prime Meridian. Prime Meridian is the main Meridian of longitude.
Point on Prime Meridian.

Show the division

It is an imaginary line that divides the earth vertically into two equal halves.
Scroll and show the additional material More information about latitudes and longitudes is available in the Additional material link.
Point to latitudes and longitudes. Let us now change the color of latitudes and longitudes for better visibility.
