Choose the correct description of a comet. A).rocky bodies that ranging in size from a meter to 900 km orbiting between Mars and Jupiter
B).concentrations of meteors called showers that the Earth passes through in its orbit annually
C).a large meteor that appears as a fireball once it strikes the atmosphere with a tail
D).bodies of ice and rock that orbit the Sun and produce a coma and tail of vapor and dust when near the Sun

D

Explanation:

Comets are cosmic snowballs of frozen gases, rock, and dust that orbit the Sun. When frozen, they are the size of a small town. When a comet's orbit brings it close to the Sun, it heats up and spews dust and gases into a giant glowing head larger than most planets.

ur answer is A).rocky bodies that ranging in size from a meter to 900 km orbiting between Mars and Jupiter.

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.
