How can you describe the shape of the earth?
The Earth is an irregularly shaped ellipsoid. While the Earth appears to be round when viewed from the vantage point of space, it is actually closer to an ellipsoid. However, even an ellipsoid does not adequately describe the Earth’s unique and ever-changing shape.
Which answer best describes the shape of Earth?
Earth is slightly flattened at the poles and bulged at the equator . That is why, its shape is described as a Geoid. Geoid means an earth-like shape.
Which is the best means of explaining the shape of the Earth in a classroom?
Scientists use geodesy, which is the science of measuring Earth’s shape, gravity, and rotation. Geodesy provides accurate measurements that show Earth is round.
What is the shape of the Earth for Class 9?
spherical shape
Answer: The earth has got a spherical shape, slightly bulging at the equator and flattened at the poles.
Why the shape of Earth is described as geoid?
The correct answer is Earth is slightly flattened at the poles. The Earth is slightly flattened at the poles. That is why it is referred to as a “Geoid”. Geoid means “an earth-like shape”.
Why is the shape of the Earth described as an oblate spheroid?
Answers. The rotation of the earth causes the earth to swell more at the equator, compared to at the poles. When the earth rotates, there is a strong outward force on the earth matter near the equator. This force causes the swelling, and gives the earth the oblate spheroid shape.
What is the shape of the Earth answer Class 6?
geoid-earth like shape
Answers: (a) The true shape of the Earth is geoid-earth like shape.
What is the shape of the Earth for Class 7?
The shape of the Earth is geoid.
What is the shape of Earth Class 6?
What is the shape of Earth Class 2?
The Earth is almost completely round. The force of gravity would pull the Earth into a perfect sphere shape, but the fast rotation of Earth on its axis, an imaginary line running from the North Pole to the South Pole, reduces the effect of gravity on the equator.
Why is the shape of the Earth?
The reduced gravity causes the land around the equator to bulge outward by about 13 miles (21km), while making the land at the poles appear flattened. This gives the Earth its true, slightly squished shape, which is called the geoid.
What is called geoid?
A geoid is the irregular-shaped “ball” that scientists use to more accurately calculate depths of earthquakes, or any other deep object beneath the earth’s surface. Currently, we use the “WGS84” version (World Geodetic System of 1984).
