Which was least likely to have been a component of earths atmosphere before life began?
oxygen
Was least likely to have been a component of Earths atmosphere before life began?
oxygen
What would earths atmosphere likely consist mostly of without the presence of life?
c water vapor
What is most likely to cause rise in the average temperature of the earths atmosphere in the future'?
Expansion of the sun. The sun is destined to eventually grow to a red giant - which will wipe out all life on earth.
Dramatic variations in the polar ice caps most likely suggest changes in?
earths climate
Which molecules are least likely to escape from earths atmosphere?
The heaviest ones.

Extremely high temperatures most likely found in this part of earths atmosphere?
Thermosphere

How would the chemicals of other planets atmosphere's react with those of earths?
Well considering most other planets with atmospheres have methane and hydrogen as major components of their atmosphere, it would likely ignite.
Was the first tornado in tornado alley?
Most likely not. Tornadoes have probably been around since Earth had the same basic atmosphere of oxygen and nitrogen, perhaps even in Earth's primordial atmosphere, long before the tornado alley we know today even existed. Most people say yes and some say no.
Where was the first black hole?
The very first black hole is believed to have likely accompanied events in the early universe where matter first formed from the tremendous energies from the big bang; such are referred to as primordial black holes. There isn't direct evidence for them nor details about their location but theoretical modelling suggests they exist. The first strong black hole candidate discovered from Earth around 1972 was in Cygnus X-1, which is an X-ray binary source; verification included trips to the upper atmosphere and observation outside the atmosphere.

Expansion of the sun. The sun is destined to eventually grow to a red giant - which will wipe out all life on earth.
Where would you be most likely to find granite in earths mantle or earths continents?
you will find it in earths mantle because it is a kind of an igneous rock
What do you mean by protoplasmic body?
It is, literally, the first body to be created. Most likely what rose from the primordial soup, as many scientists believe.
Where would a satellite revolving around earth land if it crashed?
It will most likely burn up through the earths atmosphere on re-entry. The satellites travel at very high speeds, and are not designed to withstand the brunt of the earths atmosphere at the speeds at which they orbit the earth. You might get some bits left over, but these should be quite small. Operators try to land the satellite in the sea once it has reached the end of its life.
