What are the two main characteristics for ALL igneous rocks?

Answers

Answer 1
Answer: Igneous rocks form from the cooling and solidification of lava or magma.

I'm not a big fan of this question, but I think the "desired" answer is grain-size (from very  large to microcrystalline) and interlocking texture.  

(It could be tendentiously argued that tuff (also called tufa) and possibly other pyroclastic rocks, which form from volcanic ejecta, lack an interlocking texture because they are more like sediments that are welded together. I say this is tendentious because such rocks are about as much sedimentary as they are igneous, and are not typical igneous rocks if they are igneous rocks at all.)

b. the countries found in the Northern Hemisphere today were once centered over the South Pole.
c. no continents occupied the Northern Hemisphere.
d. the countries found in the Southern Hemisphere today were once centered over the North Pole.

Answers

The answer is A. There is evidence from geologic rocks that there was an ice age 2.4 billion years ago and the glaciers had reached Western Australia and India. This ice age is associated with the cooling of the earth due to the Great Oxygenation event when the earth was filled with oxygen produced by photosynthetic organisms hence reducing the amount of greenhouse gases in the then atmosphere. There have been four other major ice ages after that.

Evidence about ancient climates indicates that glacial ice once covered much of what is now India and Australia. The correct option among all the options that are given in the question is the first option or option "a". The end of ice age also was the start of new life on planet earth. I hope the answer helps you.
