What will happen to the marble if it gets too close to Earth?
If it gets too close to the center, however, the marble gets sucked in and cannot escape—just like light cannot escape if it ends up inside a black hole’s event horizon.
Would a marble orbit a bowling ball?
If a marble and a bowling ball were placed in a space where there was no other gravity acting on them, or any forces at all, would the marble orbit the bowling ball? No. They will just be pulled to each other. Only if the marble is travelling between about 0.000041 and 0.000057 m/s.
What will happen if the Earth gets bigger?
The face of the bigger Earth will become very different, considering that volcanic activity can change its shape and create new land. Climate change might also follow because gases from eruptions affect the atmosphere. Only the tiniest part of the Universe has been explored.
What is the difference between the Earth’s crust and the mantle?
Beneath the crust is the mantle, which is also mostly solid rocks and minerals, but punctuated by malleable areas of semi-solid magma. At the center of the Earth is a hot, dense metal core . Earth’s layers constantly interact with each other, and the crust and upper portion of the mantle are part of a single geologic unit called the lithosphere.
What would happen if the diameter of the Earth doubled?
If Earth’s diameter doubled but density was similar to the old Earth, the planet’s mass would go up and gravity would be twice as strong. That would instantly make your weight twice as much as it was before.
How does the mantle affect the landscape of the Earth?
The transfer of heat and material in the mantle helps determine the landscape of Earth. Activity in the mantle drives plate tectonics, contributing to volcano es, seafloor spreading, earthquake s, and orogeny (mountain-building).
