Answer:
Sources of extraterrestrial rocky matter are cosmic dust and meteoroids, moon rocks.
Explanation:
- Sources of extraterrestrial water exist exclusively in ice layers, small amounts of water vapors. Ice giants like Uranus and Neptune have supercritical water oceans beneath the clouds.
- The presence of geysers on Saturn and Europa and Jupiter's of the moon contain vapors of water. Other glaciation evidence also helps proves the presence of oceans as the subsurface oceans came into consideration through the evidence collected from the past geological evidence.
- Venus had the premedial oceans like oceans on mars in the northern hemisphere. Comets also consist of large parts of icy waters due to there distance from the sun.
- The composition of iron and sulfur are the majorly two compositions of finding on the red planet of Mars.

Explanation:
Carbon dioxide and methane are called greenhouse gases. The property of greenhouse gases is they they heat energy in them and does not let it escape.
Both Carbon dioxide and methane when present in atmosphere, absorb heat from sun and heat which would is reflected from the Earth's surface. With increase in fuel consumption release of these gases has grown tremandously. Thus, with increase in Carbon dioxide and methane more and more heat is being trapped in the atmosphere and therefore, the Earth's average is rising decade after decade.
