Metal ores
Explanation:
in an area where subduction has occurred in times past, metal ores are likely to be found.
Metallic ores find subduction zone regions very favorable to crystallize out of a magma.
- Ores have different modes of formation.
- Typically, they are found in hydrothermal vents and black smokers of igneous intrusives.
- These are igneous terrains where metallic sulfides and other minerals crystallize out of magmatic body.
- Metals in magma usually have large sizes and do not partition easily in the melt.
At a subduction zone, partial melting of the subducting plate forces magma into nearby country rock as an intrusive and to the ocean floor where they form black smokers.

The work done to push the box is equal to the product between the force and the distance through which the force is applied:
In our problem, the force is F=1.4 N and the distance covered is d=150 m, so the work done by pushing the box is
Answer: "One object speeds up before it slows to a stop
"
(the top one)
Explanation:
Ok, first a little recall on how to read this type of graph.
If the points are far apart, the object is moving fast.
If the points are close together, the object is moving slow.
If the distance between the points changes then the velocity of the object changes, which means that the object is accelerated.
If we have a lot of points clustered in one location, then the object is not moving.
We can see:
The top object starts slow, then it increments the speed, then it slows down again, and then it comes to stop.
The bottom object starts fast, and it slows down.
then:
"One object speeds up before it slows to a stop
"
This describes the motion of the top object, this is the only correct option that describes one of the graphs.
