Because if the axis wasn't tilted the sun wouldn't shine on the top of the earth.
Answer: None, it would be 24 hours of darkness
Explanation:
This is because December 21st marks the astronomical start of winter for the northern hemisphere with the winter solstice. During this season the days are shorter than the nights, and as we get closer to the North Pole, we will have up to 24 hours of darkness.
That is why on December 21st, the sun is not visible for 24 hours and the next days (the closer it is to the north pole) it will stay that way. Therefore, the inhabitants of this area will have longer periods of darkness.
Slowly, deep underground
The igneous rock gabbro is coarse grained and non-vesicular. Both characteristics show that it is an intrusive igneous rock. Intrusive igneous rocks are formed below Earth's surface and slowly (because they're underground). When rocks are intrusive, they are are non-vesicular (no air pockets) because the air has had the time to escape because of the slow cooling time period. Intrusive rocks are also coarse because crystals had the time to form in the rock during that longer cooling time.
Ps. extrusive igneous rocks form rapidly at Earth's surface and basically have tge opposite characteristics for the opposite reasons (ex: vesicular cause air had little time to escape)
