How big is the largest known asteroid a. about 100 kilometers in diameter b. about 10,000 kilometers in diameter c. about 1,000 kilometers in diameter d. about 10 kilometers in diameter

I think the answer is C.

Option (C)

Explanation:

The asteroids are the astronomical objects or rocky bodies that are present mostly in the asteroid belt between Mars and Jupiter. These objects move around the sun.

The largest known asteroid is the Ceres, which has a diameter of about 940 km. It is almost equivalent to 1/4th of the moon size and is present in the asteroid belt.

Thus, from the given option, this asteroid is approximately 1,000 kilometers in terms of diameter.

Hence, the correct answer is option (C).

since there isn't any suggested answers i will give you the reason and hopefully you can figure it

south africa, or rather all of africa, has not been in the location in which it is nowadays throughout the geological past. after the super-continent pangaea started to break apart, gondwanaland, in which was africa, moved further south, and parts of it came to be very close to the south pole. because the climate in this part of the world is very cold due to the very dispersed sun rays in there, what is now south africa, started to freeze, and the conditions were right for the formation of glaciers. the glaciers existed up until the period when gondwanaland started to break apart and what is now africa started to move towards north, sp it warmed up and the glaciers melted.
