What's the relationship between Specific retention and specific yield?
Both Specific retention and specific yield relate to the ratio of the volume of water (in a permeable unit of rock and/or sediment) to the total volume of the rock and/or sediment, as it relates to gravity. Specific retention is the ratio of the volume of water that is RETAINED against the pull of gravity, ...where-as specific yield is the ratio of the volume of water that is EXPELLED (yielded) against the pull of gravity. Again, ...both as a ratio to the total volume of the rock and/or sediment.
Why water inside a rock crevice can split it apart when the temperature drops?
Water inside a rock crevice can split it apart when the temperature drops because water expands when it freezes, creating a significant amount of force that can widen existing cracks in the rock. This process, known as freeze-thaw weathering, occurs as water seeps into cracks, freezes, and then expands, eventually breaking the rock apart over time.
Why would the amount of salt obtain from rock salt be less than the mass you started with?
The amount of salt obtained from rock salt may be less than the mass you started with due to impurities and the presence of other minerals within the rock salt. During extraction and purification processes, some of the material may not be soluble or may be lost as waste. Additionally, moisture content can also affect the final yield, as some of the mass may be water that evaporates during processing.
How it is possible for a rock to float in water?
A rock floats in water due to buoyancy, which is the upward force exerted by the water on the rock. If the rock is less dense than the water, it will displace an amount of water equal to its weight, causing it to float. Additionally, surface tension can also play a role in helping small rocks or pebbles float on the surface of water.
What type of natural materials makes the best aquifers?
Porous materials like sandstone and limestone make the best aquifers because they have interconnected spaces or pores that can store and transmit water. These materials allow water to flow through them easily and hold a significant amount of groundwater.

What is an easy rock experiment?
Fill a graduated cylinder full of water, than drop a rock inside. The amount that the water rises will determine the volume of the rock. Amount of water level increase=volume of rock.

Permeable rock layers or sediments that transmit groundwater freely are called?
Permeable rock layers or sediments that transmit groundwater freely are called aquifers. Aquifers can store and yield significant quantities of water, making them important sources of groundwater for wells and springs.
How much force does it take to brake a rock?
The amount of force required to break a rock depends on its composition, size, and density. It typically takes a significant amount of force, such as that generated by machinery or explosives, to break a rock.
What is the amount of space in a rock that holds air or water?
The amount of space in a rock that holds air or water is called porosity. Porosity is a measure of the void spaces in a rock and can vary depending on the rock type and how compacted it is. It is an important factor in determining how easily fluids like air or water can flow through the rock.
How do you find the volume of a rock?
place the rock in a large container that is fillec to the brim with water, making sure you know how much water you put in. Place a tray underneath (or something similar) and place the rock in. Wait until the water stops moving, then measure the amount of water on the tray. The amount of water in the tray is the volume of the rock. E.g. the water in the tray was 20ml, so the volume of the rock is 20cm3.
How could you find the volume of a small rock using a graduated cylinder and water?
Fill the cylinder about half way with water and measure the amount. Then drop the rock in and measure the amount of water. Now subtract no rock from rock in and that will give you the amount of volume displaced from the rock.
Do rocks sink in water?
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.
Does a rock weigh more in 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.
When a rock is placed in a container full of water it displaces 250ml of water The mass of the rock is 5.63 times the mass of the water what is the volume and mass of the rock?
The volume of the rock is the amount of water it displaces, 250ml. Considering that 1ml of water has a mass of 1 mg, the mass of the rock is 5.63 x 250gm = 1,407.5mg.
Which of the following is true when a rock sinks in water?
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.
