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.
Well, if you mean layers of the earth than the 1st one would be crust the second would be the mantle and the third would be the outer core.
Answer:
150 million years old
Explanation:
If we have an isotope that has a half-life of 50 million years, we need just need to divide the numbers in order to get to one eight of the full number, than multiply it by 50 million in order to get the result.
If one half is 50 million years, than dividing one more half, which will gives one fourth of the total, will brings us to 100 million. Dividing the one fourth by two will leads to the one eight of the full number, and adding 50 million more years, we get 150 million years. So the rock in question has 150 million years of age.
Answer:
No,you are most likely to see volcanic mountains where Magma is rising along the mid Ocean ridge spreading centre.
Answer:
Earth's varying distance from the Sun,
Explanation:
There has been an established fact that the sunrise and sunset times varies because of the earth’s tilt in its orbit and its varying distance from the sun. At different locations on the earth, the times when the sun comes up and goes down would certainly be different on any given day. The north of Gisborne in New Zealand witnesses the world's first sunrise each and every day.
