The Earth has many phases throughout the year in which it actually changes shape. During Spring it is an Asterisk.
During Summer it is a triangle.
During Autumn it is a cube.
During Winter it is an Oblate Spheroid.

It is not an actual sphere.This is since that when the earth turns on its axis so quickly for twenty four hours ,the poles seem a bit flat and the sides east and west are bit rounder.It is an OBLATE SPHERE !
The shape of the Earth most closely resembles a slightly flattened sphere known as an oblate spheroid. This means it is slightly wider at the equator than it is from pole to pole.
The fruit that most closely resembles the shape of the Earth is the orange. Oranges are generally spherical in shape, much like the Earth, although they may have slight variations in size and texture. The orange's round shape and color can be reminiscent of the Earth when viewed from a distance.
Venus is the planet that most closely resembles Earth in size and composition. It has a similar mass, size, and density to Earth, as well as a rocky surface. However, Venus has a thick atmosphere of carbon dioxide that creates a runaway greenhouse effect, making it extremely hot and inhospitable.
Slate most closely resembles shale when it comes to sedimentary rocks. Both are composed of fine-grained minerals, have a layered structure, and are formed from the compaction and metamorphism of pre-existing sedimentary rocks. Slate is a metamorphic rock derived from the low-grade metamorphism of shale.
Earth is modeled as a sphere because it is the most simple and efficient shape that closely approximates the actual shape of the Earth. This simplification allows for easier calculations and predictions in areas like geography, climate, and navigation. It also provides a basis for understanding fundamental concepts like gravity and the distribution of land and water on the planet.
Yes, the composition of the moon's mantle is similar to that of Earth's mantle in terms of silicate minerals and elements like magnesium and iron. This similarity suggests that the moon's mantle may have been formed from materials that were also present in the Earth's mantle.
