It was kind of a stressful situation because it had as for me to write in black ink and if I would have messed up I would have to do it over again and it had a weird organizational pattern because it would start with your weakness then strengths in on spot and ask for it the other way around in other spot
Im not sure what you mean but, <span>Plate tectonics is the theory that the outer rigid layer of the earth (the </span>lithosphere) is divided into a couple of dozen "plates" that move around across the earth's surface relative to each other, like slabs of ice on a lake. the theory can best be described as <span>earth's natural process by which its lithospheric plates slowly move about because of movement in the asthenosphere. </span>

Answer: c) The formation of the ice age glaciers occurred about 21,000 years ago.
Explanation:
The last glacial period occurred in the period between 115,000 - 11,700 years in the past with the recent glacial period called Quaternary glaciation. Though some call this period the last ice age, it is a wrong definition because ice age is defined by year-long ice which still persists in the Antarctica and Greenland. The last glaciation that occurred 21,000 years in the past, is the last glaciation on Rocky Mountain.
It occurred in the period 31,000 - 10,000 years and between 23,500 - 21,000, it was at its highest. The glaciation was not made of the giant ice sheet but was made of mountain glaciers known as Cordilleran Ice Sheets. These sheets produced Lake Missoula which late caused Missoula flooding.
Answer:
It's complex, but it is related to the velocity of the asteroid, the orbital velocity of the planet, the gravitational pull of both, and the asteroids angle of attack.
