How is The environment on Mars different from that of Earth’s?

Pavlova-9 [17]

Answer:

Mars is about half the size of Earth by diameter and has a much thinner atmosphere, with an atmospheric volume less than 1% of Earth's. The atmosphere of Mars is about 100 times thinner than Earth's, and it is 95 percent carbon dioxide.
The atmospheric composition is also significantly different: primarily carbon dioxide-based, while Earth's is rich in nitrogen and oxygen.
Because of the differences in atmospheric densities and distances from the sun, the temperature within the atmosphere are also wildly different. Earth generally ranges from 14 degrees Celsius to 70.0 degrees, whereas Mars ranges from -146 degrees C to -140 degrees C.
Both planets have a silicate mantle surrounding their cores and a surface crust of solid material.
Earth and Mars’ both have terrains that varies considerably from place to place.

Which is biotic? water temperature beeswax snow

Luden [163]

Bees wax is biotic.

Biotic means something that is related to or resulted from living things. Bio means life. Bees wax are produced by honey bees. It comes from a living thing, thus, it is biotic.

Water, temperature, and snow are all abiotic. Abiotic means "no life" or nonliving. They are not derived from any living thing.
