Question

Mention any two uses of a globe.

Answer 1

Flat maps are created using a map projection that inevitably introduces an increasing amount of distortion the larger the area that the map shows. A globe is the only representation of the Earth that does not distort either the shape or the size of large features – land masses, bodies of water, etc.

The circumference of the Earth is quite close to 40 million metres.[1][2] Many globes are made with a circumference of one metre, so they are models of the Earth at a scale of 1:40 million. In imperial units, many globes are made with a diameter of one foot, yielding a circumference of 3.14 feet and a scale of 1:41,777,000. Globes are also made in many other sizes.

Sometimes a globe has surface texture showing topography; in these, elevations are exaggerated, otherwise they would be hardly visible. Most modern globes are also imprinted with parallels and meridians, so that one can tell the approximate coordinates of a specific place. Globes may also show the boundaries of countries and their names.

Many terrestrial globes have one celestial feature marked on them: a diagram called the analemma, which shows the apparent motion of the Sun in the sky during a year.

Globes generally show north at the top, but many globes allow the axis to be swiveled so that southern portions can be viewed conveniently. This capability also permits exploring the earth from different orientations to help counter the north-up bias caused by conventional map presentation.

Answer 2

Dear Student,

● Globe of earth -

• Earth globe is a spherical model of Earth which gives us idea about shape & relative locations of earth.
• Vertical lines represent meridians of longitude. They are 360 in number.
• Horizontal lines represent parallels of latitude. They are 181 in number.
• Graticules are lines showing parallels of latitude and meridians of longitude for the earth.

# Uses of globe -

1. It gives a true picture of land and water present on earth.
2. It explains the rotation of earth.
3. Globe is used by teachers to explain about earth.

Thanks dear. Hope this helps you...
