b)Hydrosphere
c)Ionosphere
d)
Thermosphere​

Answer 1

Answer:

b)Hydrosphere,

The hydrosphere (from Greek ὕδωρ hydōr, "water"and σφαῖρα sphaira, "sphere") is the combined mass of water found on, under, and above the surface of a planet, minor planet, or natural satellite. Although Earth's hydrosphere has been around for about 4 billion years, it continues to change in shape. This is caused by seafloor spreading and continental drift, which rearranges the land and ocean.
