As well as the mediterranean, people for thousands of years relied on the Mediterranean Sea for their food and even their transportation.
Prime meridian divides the earth into western and eastern hemispheres
Answer:
They are weather systems that happen to spin in a counterclockwise direction in the Northern Hemisphere from low pressure points. They form between two big cold fronts when their temperatures are very different compared to each other. These air masses will blow past each other in opposite directions when it is formed.
Meteor = Space rock
Asteroids= small rocky object
Comets= ball of ice
Planet= travel around starts
Orbital radii= average distance from sun
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)
