What will happen when gravel touches water?

The Gravel will absorb the water until it can absorb anymore.


How long does gravel hold water in it?

Gravel does not actually hold water in the sense of absorbing or retaining moisture like a sponge. Instead, water flows through gravel easily due to its porous nature, making it a good material for drainage and preventing water buildup in soil.


Are gravel plants and water a mixture if they are placed in a fishbowl?

you can wait until the water evaporates


What does gravel look like and what is its reaction to water?

Gravel is a small, rounded rock typically in varying shades of gray, brown, or tan. When mixed with water, gravel does not dissolve or react chemically, but it allows water to pass through easily due to its porous nature.


What would happen to a frog if it were placed in the Atlantic Ocean?

It would die. Frogs have a porous skin and the slat in the sea water would quickly kill it, because fogs are adapted to live in fresh water.


Do 100 ml of gravel and 100 ml of water have the same mass?

No, the gravel sinks when placed in water and is therfore more dense than water. This means that given two equivalent volumes one of water , one of gravel, the mass of the gravel will be greater than that of the water.


What will happen if mix gravel and water together?

When gravel is mixed with water, the gravel will not dissolve or undergo any chemical reaction with the water. The gravel will remain suspended or settle at the bottom of the water due to differences in density. The water may become cloudy initially due to the particles of gravel being dispersed, but eventually, the gravel will settle down, leaving clear water on top.


What is the capacity of porous material such a sand and gravel to transmit water?

The capacity of porous materials like sand and gravel to transmit water is referred to as hydraulic conductivity or permeability. These materials typically have high porosity and larger pore spaces, allowing water to flow through them more easily compared to finer materials like clay. The efficiency of water transmission in sand and gravel is crucial for various applications, including groundwater recharge, drainage systems, and construction. Overall, their ability to transmit water is significantly influenced by factors such as grain size, shape, and arrangement.


Can microbes live in between gravel?

Yes, microbes can live in between gravel. The porous spaces in gravel can provide a habitat for microbes to thrive, as they have access to water, nutrients, and oxygen needed for their survival. Gravel can act as a biofilter, promoting the growth of beneficial microbial communities that help break down organic matter and maintain water quality.


How do you know if a rock is porous?

You can determine if a rock is porous by observing if it has small holes or open spaces on its surface. Porous rocks will also generally have a high water absorption rate when placed in water, causing them to become heavier. Conducting a porosity test, such as measuring the volume of water absorbed by the rock, can also help determine its porosity.
