It doesn't.
To calculate the volume of a rock, you can use the formula for the volume of a sphere (4/3 * pi * r^3) if the rock is spherical, or use the formula for the volume of a rectangular prism (length * width * height) if the rock has a more regular shape. Otherwise, you can measure the volume by water displacement: submerge the rock in water and measure the increase in water level to find its volume.
it is easiest to do with small rocks, but can be dome with anything if you can move it and have a container large enough to hold it. place water into a container with measurment markings and place the rock into it. the amount the water level rises, called displacement, is the volume of the rock.
The density of the rock can be directly determined when the rock is placed in an overflow container. By measuring the amount of water displaced by the rock, its volume can be calculated, and then by dividing the mass of the rock by its volume, the density can be determined.
When water in little fractures or cracks in a rock freezes, and since water expands when it freezes, it causes the crack to enlarge a little bit. The cycle of this happening over and over until the cracks are big enough to split the rock apart is Frost Wedging.
Water can carve rock through a process called erosion. Over time, water carries sediment and debris that scrape and wear away at the surface of the rock, creating channels and shaping the landscape. Factors such as water speed, volume, and the type of rock all influence how quickly erosion can occur.

Body of water has large mass and volume. Rock has got less mass and volume. But still the rock sinks in the water. The reason is very simple. Density of the rock is more than water. Mass upon volume of the rock is more than water. So rock sinks in the water. That means rock is heavier than water, if the volume of both is same. Alternately the if you take the same mass of both, rock and water, volume of the rock is lesser than that of water.
No, a rock does not weigh more in water. When submerged in water, the rock displaces an amount of water equal to its own volume, leading to a buoyant force that reduces its apparent weight. So, the rock will weigh less in water compared to in air.
The volume of the rock is equal to the volume of water it displaces. Since 400 mL of water is displaced when the rock is dropped into the jar, the volume of the rock is 400 mL.
One way to do it is fill a graduated cylinder with water and record the number, next put the rock in the water and be careful not to spill any water. Record the volume of the rock and the water together. The difference in the volumes is the volume of the rock.
The rock with a volume of 4ml has more mass, assuming all other factors are the same. Mass is directly proportional to volume, so a rock with a larger volume will have more mass.

Fill a beaker or measuring cylinder with water and record the volume of water indicated. Put the rock in the beaker/measuring cylinder and record the new volume of water indicated. The difference between the two volumes is the volume of the rock.
To measure the volume of irregularly shaped rocks, you can use the water displacement method. Submerge the rock in a container of water and measure the change in water volume as the rock displaces the water. The difference in water volume before and after submerging the rock will give you the volume of the rock.
Drop it in water. Fill a graduated cyllinder with water to cover the sample and record the volume. Then gently lower the rock sample into the water and record how much the water rose. The difference is the volume of the rock. Drop it in water. Fill a graduated cyllinder with water to cover the sample and record the volume. Then gently lower the rock sample into the water and record how much the water rose. The difference is the volume of the rock.
The weight of the rock will be lessened by the weight of the same volume of water. If the rock weighs less than that volume of water, it will float (as does pumice). Thus, if you had a rock that has a density (weight/volume) of 2 times the same volume of water, it would weigh one half of its dry weight when in water.
Place a specific amount of water in your bottle. Record the volume. Place the rock in the bottle. Read and record the new volume of water. Subtract the first volume measurement from the measurement after you added the rock. The difference is the volume of the rock.
