The arrows represent convection and how magma flows through the mantle. When a divergent boundary is formed, the land sinks into the mantle and goes through the convection system.
earth's magnetic feild
As earth formed, most planetesimals were attracted by the earth's gravity and coalesced with earth.
Hologams to represent the Earth would be too expensive.
Considering the Earth was Molten when it was formed, the temperature has actually decreased.

Strips of ocean-floor basalt record the polarity of earth's magnetic field at the time the rock formed. These strips form a pattern that is the same on both sides of the mid-ocean ridge. the pattern shows that ocean floor forms along mid-ocean ridges and then moves away from the ridge.
when earth is formed that time it formed gas such as oxy etc.......

Uranium is formed by nuclear synthesis in supernovas and at the 'big bang'. When the earth formed Uranium became a part of the forming earth.
Hologams to represent the Earth would be too expensive.
it is formed 2 miles away from the earth
The globe represent the world; or in this case, Earth.
A landform is naturally formed feature on earth's surface.
The earth's atmosphere is very old. It was formed when earth was formed.
The materials that formed the Earth are in fact OLDER than the Earth, because they were around BEFORE the Earth was formed. The Elements that you are made of were formed inside STARS before the Earth ever existed.
