Things sink in water when their density is greater than that of water. Water has a density of 1000 kg/m3, rock exceeds this by a significant amount. The principle at work is that things sink if they water tey displace weighs less than the mass of the object.

Everything in or on water pushes some water aside even if it's just a little bit What is this called?
This is called "displacement", as the weight of water that moves is equal to the weight of the object on the water. Heavier objects displace more water. If the total weight of the object is greater than the water displaced by its volume, it is denser than water, and sinks.
Which of the following statements about fluid pressure is correct SEE Discuss for choices?
"If you are 15 ft. under water, the pressure will be the same no matter how large the body of water is" is a true statements about fluid pressure.
A falling rock has kinetic energy?
True.
Why does wood float and metal sink?
Because the wood's density (which is a measure of mass in a certain volume) is less than that of water, while iron's is higher. Hence why 1 cubic centimeter of wood weighs less than the same volume of water.
Is salt water is denser than fresh water true or false?
that is true
Is it true that sand sinks in water because water is more dense than sand?
No. Sand sinks in water because sand is more dense than water, not the other way around.
Is an object neutrally buoyant when it displaces an amount of water less than its own weight?
No, it sinks

all
Which of the following is a mixture but not a solution?
We need to know what 'the following' are to answer the question!
Does weathering happen when bits of rock are moved by water or ice?
weathering happens when bits of rock are moved by water or ice true or false
Is it true that as the new seafloor moves away from the ridge and becomes hotter it moves upward and forms still higher ridges?
No. The rock cools down as it moves away and sinks deeper.
Is it true the higher the density the faster the mineral sinks?
yes !
Is the following sentence true or false when solid mantle rock rises during seafloor spreading magma is produced as a result of decompression melting?
true
Is it true or false that Chemical weathering occurs when the minerals in a rock react to water oxygen or acids in the environment?
yeah it is true and through that reaction it cause the rock to dissolve slowly
Which type of the following is true of clouds at medium altitudes?
mostly water
