That the Earth is basically shaped like a ball.
No, theres not! . Charmed is just a TV show! Its not real! :O
Shadows can provide information about the depth and direction of geological features, such as mountain ranges or volcanic peaks, on the surface of the Earth. By studying the lengths and angles of shadows, geologists can infer the approximate shape and elevation of land formations, helping to better understand the Earth's interior composition and structure.
shadows are formed when light is obstructed by an opaque body. Shadows resemble shape but not necessarily the size of the object
If the Earth were flat, its shadow could potentially take the shape of a rectangle or square if the light source was directly perpendicular to the Earth's surface. The specific shape would depend on the angle of the light source and the orientation of the flat Earth.
Aeroplanes DO cast shadows on earth, I have seen many. They are usually easier to see from the air.
Shadows give us information about shapes of objects. Sometimes, shadows can also mislead us about the shape of the object. :)
Shadows are all about the Earth's rotation. As the Earth rotates throughout the day, the relative positions of the sun and Earth change. The sun is the primary light source for shadows, and if the light source is changing positions (this is relative to earth), then the shadows will change.
Globe is the best representation of the earth because it shows the shape of the earth, which is spherical and it makes it easy to show how the earth revolves and rotates.
Sphere shaped
During an eclipse of the moon, the edge of Earth's shadow is always the arc of a circle. Only spheres casts circular shadows; a flat surface would not do so.
Measurements taken from space show the Earth to be round in shape, with a diameter of approximately 12,742 kilometers at the equator. The Earth's circumference is approximately 40,075 kilometers.
How does the angle and intensity of light affect the size and shape of shadows cast by objects?
