A rock that forms from other rocks due to heat and pressure beneath the Earth's surface is called a metamorphic rock. Examples include marble, slate, and gneiss.

Yes, different types of soil have varying capacities to hold water. Soil texture, structure, and organic matter content all influence the ability of soil to retain water. For example, sandy soils tend to drain water quickly, while clay soils hold onto water more effectively.

A cotton ball is thinly attached with lots if air between its fibers. It would be hard to find a liquid it doesn't float on, so the answer is yes to both.

In humans there is a bone named the 'cuboid' , it is the 'heel' bone in the foot.

It depends on the temperature of the sand and the ice! Sand does not dissolve in water to any significant extent, so that mixing sand with ice will not lower the melting point of the ice. If there is a sufficient amount of sand and it has a temperature above the freezing point of water, sand will eventually melt ice by heat conduction from the sand to the ice. If the sand has a lower temperature than the ice, mixing them will never produce melting of the ice.

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.

The abiotic factors of the rainforest ecosystem are the amount of water and sunlight, climate, weather and precipitation. these things affect the trees and animals that live there. These are very important because without the right amount of water and sunlight the trees in the rainforest would not be able to grow and would die.

it all boils down to just water and sunlight

The reactants and the products must contain the same numbers of the same types of atoms, that is, atoms with the same atomic number, and either the products must contain at least one type of chemical bond distinct from any chemical bond in the reactants or the reactants must contain at least one type of chemical bond not found in the products.

At Utah Idaho Map world if you live near one or at your local Home Depot or Lowes. That should help.

Both Spread-plate and pour plate method don't give the same results. Because in the case of spread plate method the inoculmn used for inoculation can't be spread in a exact volume. A little inoculmn remains stick with the spreader after spreading. On the other hand, in pour plate method it doesn't happen. So mostly, through comparing the counts by both methods, less counts are obtained in spread plate method.

Cryogenic freezing has been successfully used on small organisms like tardigrades and certain types of human cells. However, there is currently no scientific evidence to suggest that cryogenic freezing can preserve and revive larger, more complex organisms like humans. Research in this area is ongoing.

The point of there being a cell wall in plants is so it could stay up sturdy and so the leaves don't overlap and all of them can absorb carbon dioxide and sunlight. Animals don't have cell walls because they need to move around, something plants can't do because they don't need to. They create their own food when we need to find it.

Gold is a solid state at 20 degrees Celsius. Gold has a melting point of 1,064 degrees Celsius and a boiling point of 2,807 degrees Celsius, so at 20 degrees Celsius it would be in its solid phase.

By finding new species of plants scientists can find new organisims/cells/tissues that they could use to help them, for example they could add other substanses or chemicals to form a medicine.

Also by finding new plants scientists can take cuttings to make more of these plants and if they adapt in a good way to help them survive better (if they develop new genes/chromosones/DNA) then they can put that gene/chromosones/DNA in other plants to give them that special feature which will make them survive for longer.

The byproducts are:

- thunder

- ash (trees hit)

- fulgurites (strands of sand glass)

- ozone

- Buckminsterfullerenes : minute quantities of the fullerenes, in the form of C60, C70, C76, C82 and C84 molecules, are produced in nature, hidden in soot and formed by lightning discharges in the atmosphere

Scientists have learned that under certain conditions, simple organic molecules can form spontaneously from inorganic compounds. They have also observed that these molecules can self-assemble into more complex structures when exposed to energy sources such as lightning or UV radiation. While these experiments offer insights into the plausibility of life arising from nonliving materials, the exact process by which life originated on Earth remains a topic of ongoing research and debate.

Syrup, because water is a poor conductor, and because syrup has lots of stuff in it besides water that conducts heat somewhat better than water. For example, if I put water in the microwave for 30 secs, it won't be as hot if I put syrup in the microwave also for 30 secs.

Yes a feather is lighter than water. Water can be gallons. A feather however is no pounds. If you have a scale at home than fill up a cup of water than get a feather, from like a scarf a pillow etc. And put the water on first, then write down the number. Then put the feather on the scale and write down that number then compare.

Earth's three major layers are the crust (solid outer layer), mantle (semi-solid middle layer), and core (solid inner layer). The biosphere is made up of the lithosphere (solid outer part of the Earth), hydrosphere (all water on Earth), and atmosphere (layer of gases surrounding Earth), where living organisms exist.

Sunlight is an abiotic factor found in a rainforest ecosystem. It is a crucial element that drives photosynthesis, which is essential for plant growth and the overall functioning of the ecosystem.

The Earth's magnetic field is constantly changing and has been fluctuating in strength and direction over geological time scales. These changes are driven by complex processes in the Earth's outer core, such as convection and flow of molten iron. The field can weaken or reverse direction over thousands of years.

To journey to the Earth's core, you would need advanced drilling equipment capable of withstanding extreme heat and pressure, specialized heat-resistant suits to protect against the high temperatures, and oxygen tanks to ensure enough breathable air. The journey would also require meticulous planning, top-notch geological knowledge, and a team of experienced scientists and engineers.

The type of soil found in African grasslands is typically nutrient-rich and fertile. It is known as "savanna soil" and is a mix of sand, clay, and other organic materials. This type of soil is well-suited for supporting the diverse vegetation found in African grasslands.

At normal pressure, anything from 50 to 100 deg C.

Season where it takes clothes longer to dry will be seasons where the atmospheric humidity is very high such as during the Monsoon season In India.
