Answer:
Oxygen
Explanation:
The earth has been divided into three major categories crust, mantle, and core which are further segregated into sub-parts. Since the crust is the outermost layer of the shell, the outer crust of the earth consists of a combination of silicon and oxygen in the majority followed by some percentage of other metals as well. <u>The percentage of Oxygen includes nearly 50% i.e. 46.6% followed by 27.7% of Silicon and the other 25.3 % includes aluminum, iron, sodium, magnesium, etc</u>. Thus, '<u>oxygen</u>' is the correct answer.
Greenhouse effect, Latitude, heat transport in the biosphere.
Answer:
Quite probably because the percentage of water in the atmosphere is a function of temperature.
Explanation:
Answer:
The determination of the numerical age of an object.
Explanation:
Absolute dating determines the numerical age of an object.
x}
Answer is give below
Explanation:
when any object or spacecraft is located exactly between Earth and Mars.
than Earth gravitational force will be exerted on spacecraft more than the Mars gravitational force.
as we know that gravity on the Mars is less than the gravity on the Earth
so spacecraft will move very slowly toward the Earth.
gravity force on Earth = 9.807 m/s²
gravity force on Mars = 3.711 m/s²
