Currently, Earth is composed of seven continents surrounded by different bodies of water Locating a specifie place would not be possible if not for Earth
models such as maps and globen. A
is a two-dimensional di wins which
can be used on flat surfaces and is easily carried on the other hand,
is a three-dimensional representation of the spherical shape of Earth. A unique
feature of a globe is Earth's tilt with respect to its North and Beuth Poles. It also
represents Earth's position relative to Sun Through time, both models have
undergone modifications to represent Earth better
A common feature of maps and alobes is the presence of
horizontal and vertical lines to form a Cartesian plane. These imaginary lines forma

coordinate system does not exist but it was drawn as a numerical referenes which
determines the locations of different places on Earth Locating places on a map ar
globe uses these lines which are represented as

that the world is spherical. Most maps usually draw these lines apart at 15

latitude which cuts the Earth in halfis called the
This line divides Earth

hemispheres. As a reference point, the equator
is read as 0° latitude. The degree
as it approaches the two poles which
are read as 90'north latitude (90°N) or 90' south latitude (90°8).
The closer the latitude is to the equator, the
the climate. The
closer it is to the poles, the
Thus, it is clear that there is a relationship
between the latitude of a place and the climate it experiences
