Filtration is the technique used to separate suspended solute particles from a solution . The chalk powder remains suspended in the solution and can easily be filtered through a filter paper , the chalk powder can be collected on the filter paper and clear solvent is collected as the filtrate.
Answer:
Ocean temperature plays an important role in the Earth's climate system—particularly sea surface temperature (see the Sea Surface Temperature indicator)—because heat from ocean surface waters provides energy for storms and thereby influences weather patterns.
increase the force needed to move the object
Explanation:
If a machine decreases the distance an object moves, it must also increase the force need to move the object.
A machine is a device that is used to do work with a little energy input.
Work done = force x distance
We see that to do more work, a lot of force must be applied to move a body through a greater distance.
If the distance is reduced;
Distance = 
More force must be applied to measure up for the distance and make the machine more efficient.
