Answer:
Mountains isolated many groups that migrated to the region. Dense forest served as a barrier to migration across the region. Vast plains facilitated the migration of people across the region.
Explanation:
CORRECT
We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.

Answer:
Tectonic plates move.
Explanation:
Earthquakes are natural disasters that occur because of movement in tectonic plates.
Answer:
(2.5, 3)
Explanation:
This question requires using the midpoint formula.
(formula is attached below as an image for better understanding)
First identify which values correspond with which variables in the formula:
First coordinate: (3, 7)
x_1 = 3
y_1 = 7
Second coordinate: (2, -1)
x_2 = 2
y_2 = -1
Now we plug the values into the formula and simplify:
((3+2)/2, (7-1)/2)
(5/2, 6/2)
(5/2, 3)
(2.5, 3
