Globes are the spherical models of the earth. The purpose of the globes is pretty much similar to the maps. The model globe which is made for the earth is simply known as the terrestrial globe. The model globe which is used for the celestial sphere is known as the celestial globe. You can find all the answers to globes in the Class 6 Geography Chapter 2 notes.

What is Latitude?
The latitude is a proper measurement on the map or a proper globe of any location which is North or the South of the Equator. The latitude can be measured with the help of a line which is imaginary and is known as the Prime Meridian. The latitude can be measured in any particular angle that ranges between 0° at the Equator to 90° at the poles Find more details about latitude in globe latitudes and longitudes Class 6 notes.
What is Longitude?
The longitude can be defined as the measurement of any particular location which is a situation to the east or the west of the Prime Meridian, that too, at Greenwich. Students will easily be able to understand these topics with the Globe latitudes and longitudes Class 6 PPT.
An Overview of Globes, Longitude, and Latitude
Globes can be of different sizes and there are many types too. You have the small globes that fit in a pocket and then there are larger ones. One of the main things about the globe is that it can easily be rotated as there is no fixed point to it. There are countries, oceans, and continents shown in the globe and their right size as well. The globe has a needle fixed through it in a titled fashion that we know is the axis.
The two extreme points through which this needle will pass is known as the two different poles, North and South. Another important line passes through the globe and it divides it into two different parts, the Northern and the Southern Hemisphere. This particular line is known as the equator. According to the NCERT Geography Class 6 Chapter 2 notes, the equator is basically just the imaginary line which is circular and can be used for locating different places on the globe. Every single one of the circles that run parallel to the equator can be called the parallels of latitudes. These are measured properly in degrees.
The equator is a representation of the zero degrees latitude. We all know that the distance of poles from the equator is about 1/4th of the entire circle of the earth. Hence, the degree measured would also be one-fourth of the entire rotation which is three hundred sixty degrees, also 90°. So, about 90 degrees to the North latitude will denote the North Pole and 90 degrees to the South would denote the South pole. Students can refer to the Class 6 Geography Chapter 2 notes for more information.
The Parallels of Latitude
There are four different and very important parallels of latitudes that students need to know about. It is all described in the chapter Globe Latitudes and longitudes Class 6 notes.
Tropic of Cancer (23½° N) is located in the Northern Hemisphere.
Tropic of Capricorn (23½° S) which is located in the Southern Hemisphere.
The Arctic Circle is situated at 66½° north of the equator.
The Antarctic Circle is situated at 66½° south of the equator.
Different Heat Zones Located In the Earth
There are different types of heat zones that are located on Earth. Students can know about it with the Globe Latitudes and longitudes Class 6 PPT.
Torrid Zones: The Torrid Zone is the area which gets maximum heat since the sun at its Mid-day is right over the head and that too at least once every single year. This happens on all the latitudes which are situated between the Tropic of Capricorn and Tropic of Cancer.
Temperate Zones: The Temperate Zone has some sort of moderate temperature. This happens when the sun in the midday doesn’t shine overhead on any specific latitude which is situated beyond the Tropic of Cancer as well as the Tropic of Capricorn. So, the areas which are bounded by these parallel latitudes in the Northern and the Southern Hemisphere tend to have some moderate type of climate.
Frigid Zones: Now these are the zones or areas that lie between the North Pole and the Arctic Circle which is present in the Northern Hemisphere and the South Pole and the Antarctic Circle which is present in the Southern Hemisphere. The reason for these zones being frigid is that the sun doesn’t rise much and that too above the horizon in these regions. So, the rays of the sun in these areas tend to always be in a slanting position. The heat produced is much lesser and these areas tend to be a lot colder than expected.
