A caldera is a large cauldron-like depression that forms following the evacuation of a magma chamber or reservoir. When large volumes of magma are erupted over a short time, structural support for the crust above the magma chamber is lost, and the entire structure caves in and forms a large bowl-like shape.

Answer:
if the weight of the object is equal to the force applied, there will be no change
if the force applied is less than the weight of the object, there won't be any change
if the force application ed is greater than the weight of the object, than the object will move.
Explanation:
here the weight referred to the force of the object.
In answering this problem, you have to know the concepts behind Newton's Laws of Motion. When a coin is tossed up in the air, the only force acting upon it is the force of gravity. It is the force pulling the object towards the center of the Earth. This acceleration, according to Newton's 2nd Law of Motion, produces a constant acceleration equal to 9.81 m/s². This is an empirical data that is specific only to circumstances on Earth.
Part a. From the starting point, you exert a force so it speeds up with an initial velocity. As it goes up, the velocity decreases because the force of gravity is constantly pulling it down. The coin will eventually reach a maximum height, where its velocity will reach zero. Afterwhich, the velocity increases again as it goes back down to the ground. The motion is now faster because it is parallel and in the same direction of the gravitational force.
Part b. As mentioned earlier, the acceleration is constant because the force of gravity is always acting upon an object. Whether it goes up and returns back down, the acceleration will always be of the same value.
