If the "tilt" of the Earth's axis were greater than it really is,
then the changes from same-climate-all-year-around, as
well as the changes from same-length-of-daylight-all-year-around,
would increase.
Summers would become even hotter and Summer daylight
would become even longer.
Winters would become even colder and Winter daylight
would become even shorter.
The higher the pressure of magma inside the volcano the higher the strength of the volcano.
Hey There,
The answer to your question is option B) Between 200 and 500 million years old.
These rocks are younger than the Earth and also younger than rocks found on continents. (Those rocks are 4-5 billion years old.)
Best Of Luck,
