B. The region experienced a surplus of food
Answer:
There is an attractive force call gravity
Explanation:
The reason the moon's inertia doesn't make it continue in a straight line is due to the attractive force of gravity and the reason the moon and earth's gravity doesn't make them collide with each other is due to the moon's inertia. To understand this phenomenon imagine that you have a ball tied to a rope, you keep the rope with one hand and with the other you push the ball so it can move freely; the ball, like the moon, has velocity, but the ball can not move in a straight line because the rope doesn't allow it, in our hypothetical scenario the rope is like the gravity that traps the ball in an 'endless' circle.
Note: The rope and the ball are a hypothetical case, it helps us imagine the phenomena but the forces involved are different than in the case of the moon.
Answer:
degrees
Explanation:
Most maps show latitude and longitude in degrees.
__
Some military maps and maps in some northern European countries may use grads for angle measurement. That usage is not common these days.
I think it is a geocentric model
Answer:
The North American Plate moves in roughly a southwest direction away from the Mid-Atlantic Ridge at a rate of about 2.3 centimeters (~1 inch) per year. At the same time, the Pacific Plate is moving to the northwest at a speed of between 7 and 11 centimeters (~3-4 inches) a year.
Explanation:
The fastest moving tectonic plate on Earth?
The Cocos and Nazca plates (in the pacific ocean) are right now the quickest, moving at over 10 cm/yr. However typical plate movements are less quick, at rates about 2-3 cm/yr.
How fast is the North American plate moving?
The North American plate is moving to the west-southwest at about 2.3 cm (~1 inch) per year driven by the spreading center that created the Atlantic Ocean, the Mid Atlantic Ridge.
