How are electromagnets temporary?
A.) They are only magnetic when an electric current runs through them.
B.) They are only magnetic when a gravitational wave runs through them.
C.) They are only magnetic when near a lodestone.
D.) They are only magnetic for two weeks.

Answers

Such magnets are called temporary magnets. An electromagnet is a temporary magnet. It is made by winding a coil of insulated wire round a soft iron core. When a current is passed through the coil, the magnetic field produced by the current magnetises the soft iron core. The soft iron core loses all the magnetism when the current is switched off.

Tree roots speed up ____ by creating and widening cracks in rocks! Tree roots slow down ____ by holding sediments in place so they're not transported away as quickly.

Answers to pick:

1) Weathering, erosion
2) Erosion, weathering

Answers

Answer:

Weathering, Erosion

Explanation:

Plants and animals can be agents of mechanical weathering. The seed of a tree may sprout in soil that has collected in a cracked rock. As the roots grow, they widen the cracks, eventually breaking the rock into pieces. Over time, trees can break apart even large rocks.

Tree root systems have a handful of large roots that branch out into a network of smaller roots that often extend out far beyond their branches do. These root systems prevent erosion by holding the soil in place and improving drainage which helps water get absorbed into the soil instead of just running over the top.

Hope this helps

How do you think other galaxies might be similar or different from the Milky Way Galaxy?

Answers

Answer:

Going off of our own galaxy, one could assume that the universe is filled with other planets, moons, and stars. The interesting thing to me would be the shape of the Milky Way. It would be interesting to see how other galaxies have formed. As in, are they spherical, oblong, in the shape of a square?

There are also endless possibilities for undiscovered metal alloys in space, which is very exciting to me. The idea of space mining has been brought up many times before, but if there are new and useful metals, precious gems, or minerals that are yet to be discovered outside of the milky way, they could help restore Earth.

Other (well all if not most) galaxies are mostly made up of stars, planets, asteroids, and dust which is something that makes it similar to our galaxy .

They can be different by different amounts of types of stars, they might have other organisms that are alive just like us but they’d be different, yk?
