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)
It happened when H2O gets released to that atmosphere to a massive heat level combined with geo force
Answer:
Megacities have an impact on public health, like contamination of water. Overpopulated places can bring diseases and a lack of health protection.
Explanation:
Megacities are the base for gas emissions that could be very dangerous for the environment. Traffic jam is getting worse day by day. Almost half of the habitant of one city spends at least one hour in the car to get to work.
Well let's see how many numbers can be divisible by 6 or 8, add them up, and then put it into a fraction.
6: 6, 12, 18, 24, 30, 36.
6: 8, 16, 24, 32, 40.
Total:
6, 8, 12, 16, 18, 24, 30, 32, 36, 40.
There are 10/40 positive numbers that can be divided by 6 or 8.
Simplified, 1/4.
