Interplanetary material select one:
a. hits earth at specific times of the year in the form of small particles that produce meteor showers, but does not fall on earth at other times.
b. falls on earth only very rarely in the form of single large objects, but these individual impacts can devastate parts of earth and threaten life.
c. falls on earth at a rate of roughly 80 tons per day, mostly as tiny particles of dust.
d. occasionally hits earth in the form of fairly large objects that form craters, but there is no continuous stream of incoming matter.

correct  answer is option c. ( falls on Earth at a rate of roughly 80 tons per day, mostly as tiny particles of dust.)

Explanation:

It is very difficult to tell exact amount of interplanetary material that hit Earth per day. Most of the meteors that hits the earth are dust sized pieces. it is estimated that the mass of material that falls on Earth is about 80 tons per day. Most of this mass come from dust-sized particles which are released by comets as their ices vaporize in the solar neighborhood. On the other hand the large size interplanetary material which hits the Earth’s originates due to collision fragments of asteroids that have run into one another some eons ago.

i think its toxic gasses but i could be wrong
