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)
<span>When
the water level of a stream or river exceeds its natural banks, it has reached
its flood stage. This is a real panic stage for people living nearby the rivers
and streams that has overflowed its natural banks. This flood situation can
destroy any city or village and also drastically impact the financial situation
of the area. Most cities and states move their citizens away from the river
banks before it reaches this danger stage. Before the emergence of
technological advancement, historical evidence proves that many great cities
were destroyed due to such situations. <span /></span>

Answer:
From the standpoint of geography, your mental map is your visualization of the spaces you come across.
Explanation:
In the sphere of behavioural geography, the phrase "mental map" stands for a person's viewpoint or perception of his/her area of interaction. Though it might seem like a subject matter that would be studied by social sciences fields, it is mostly studied by modern-day geographers. Mental maps are important as they provide people with crucial means of making sense of the world. They also help in storing and recalling information about the patterns of the Earth's physical and human characteristics. Example: Picturing one's neighbourhood, one can visualize where the roads go and where the houses are located including landmarks.
Answer:
Once the fusion reactions begin, they exert an outward pressure. As long as the inward force of gravity and the outward force generated by the fusion reactions are equal, the star remains stable.First, stars fuse hydrogen atoms into helium. Helium atoms then fuse to create beryllium, and so on, until fusion in the star's core has created every element up to iron.
