Where are you right now? How do you find the exact position of someone or something on the earth? Today, with the aid of satellites, we use Global Positioning Systems (GPS) to find the exact location of someone or something on this earth. How do you interpret the numbers that a GPS device gives you? What if the GPS device is not working? What if, as often times occurs, the GPS system is wrong? For these reasons and more, knowing how to use latitude and longitude to find a an exact location is useful. Also, knowing latitude will provide you an idea of the climate of a place.

A) Lines of latitude are imaginary lines that run completely around the globe-full circles. If you travel along any of these lines you are going east or west.

B) All lines of latitudes are parallel. This means that no matter how far two lines of latitude are extended they would never meet. Looking at the lines of latitude on the schematic to the above you see that these lines never touch and stay equidistant (same distance) apart all around the earth. They are parallel and often times are called parallels.

C) The equator is numbered 0 degrees or 0°. The equator divides the world into two equal halves called hemispheres: the Northern Hemisphere and the Southern Hemisphere. All places that are north of the equator are said to have north latitude. All places south of the equator are said to have south latitude.

D) So place E marked on the schematic has a north latitude and place G has a south latitude.

E) To prevent maps from becoming too cluttered with lines, cartographers (map makers) show only a few lines of latitudes (parallels), generally 10 or 20 degrees apart. The schematic shows lines of latitude that are 10° apart. Starting from 0°, the equator, the lines of latitude are numbered north and south to 90°. The North Pole is 90° N and the South Pole is 90° S.

What line of latitude is point C on? If you said 40 degrees north, then you are correct.

What about point K?

You can easily determine how many degrees separate one place from another place. For example, B is on the 60°N line of latitude; C is on the 40°N line of latitude. By subtracting we find that B is 20° further north than C. Another way to find how many degrees separate one place to another is to count the number of lines of latitude that separate the two points and multiply by latitude of separation (in this schematic it is 10°).

G. A single degree of latitude is approximately 69 miles apart (68.9 miles to be more exact). Therefore, every lines that are 10 degrees apart is 690 miles. Use the schematic to determine the distance.
1) How many miles is it from point B to point F?
2) How many miles is it from the North Pole to F?
3) How many miles is it from point F to point G?
4) How many miles is it from the North Pole (90°N) to the South Pole (90°S)?
H. As you learned previously, because of the Earth's relationship with the sun, there are three major climate zones. They include the Tropical, Temperate, and the Polar Zones.

The tropical climate zones are also called the "Lower Latitudes." The tropics are near the Equator and extend to 23.5° (even to 30° in some places) North and South. Characteristics of the tropics are as follows:
The tropical climate zones are also called the "Lower Latitudes." The tropics are near the Equator and extend to 23.5° (even to 30° in some places) North and South. Characteristics of the tropics are as follows:
Climate: Warm or hot year-round due to consistent direct sunlight.
Weather Patterns: High humidity, frequent rainfall in tropical regions, and dry conditions in desert areas. Hurricanes form in the waters of the tropics.
Ecosystems: Tropical rainforests, savannas, and deserts dominate these regions.
Examples: The Amazon Rainforest (South America), the Sahara Desert (Africa), and Southeast Asia.
The polar climate zones are also called the "higher latitudes". They extend from the poles to 66.5° (even to 60° in some places). Characteristics of the polar zones include:
The polar climate zones are also called the "higher latitudes". They extend from the poles to 66.5° (even to 60° in some places). Characteristics of the polar zones include:
Climate: Cold temperatures with long winters and short summers.
Weather Patterns: Less direct sunlight, leading to lower temperatures and snow-covered landscapes.
Ecosystems: Tundra, boreal forests (taiga), and ice-covered regions.
Examples: Northern Canada, Siberia (Russia), and Antarctica.
The temperate climate zone, also called the "middle latitudes" lie between the polar and tropical climate zones in both hemispheres between 23.5°3 and 66.5° (30°–60° N/S). Middle latitude characteristics include:
The temperate climate zone, also called the "middle latitudes" lie between the polar and tropical climate zones in both hemispheres between 23.5°3 and 66.5° (30°–60° N/S). Middle latitude characteristics include:
Climate: Moderate with distinct seasons, including warm summers and cold winters.
Weather Patterns: More variable weather due to the mixing of warm and cold air masses.
Ecosystems: Deciduous forests, grasslands, and Mediterranean climates.
Examples: Most of the United States, Europe, and parts of China.
Latitude plays a key role in climate, daylight hours, and seasonal changes, affecting agriculture, human settlements, and biodiversity.
Summary Lines of latitude, also known as parallels, are imaginary horizontal lines that run east to west around the Earth. They measure the distance north or south of the Equator, which is designated as 0° latitude. Each degree of latitude is about 69 miles apart.
These lines help in navigation, mapping, and determining climate zones. Key lines of latitude include the Equator, Tropic of Cancer (23.5°N), Tropic of Capricorn (23.5°S), Arctic Circle (66.5°N), and Antarctic Circle (66.5°S). Latitude coordinates are used alongside longitude to pinpoint exact locations on Earth.
