Why is air a poor conductor? Air may be a bad conductor of heat because its molecules aren’t in continuous contact with one another. Air molecules are too far to disperse heat to at least one another efficiently. Heat is transferred or conducted by molecules and atoms that are very closely bonded together and vibrating […]
Can you make diamonds without pressure?
Can you make diamonds without pressure? Diamonds are formed when carbon is placed under an immense amount of pressure which equals 725,000 pounds per square inch. How much pressure can a diamond take? Used in so-called diamond anvil experiments to create high-pressure environments, diamonds are able to withstand crushing pressures in excess of 600 gigapascals […]

Why is lichen a pioneer species?
Why is lichen a pioneer species? Lichens are typically the first organisms to colonize bare rock. They are therefore the pioneer species in primary succession. Many organisms require soil before they can colonize an area. Lichens that colonize bare rock secrete acids that break down the rock and start the soil-production process. What is the […]
Why the water level inside the bottle remained the same all throughout the activity?
Why the water level inside the bottle remained the same all throughout the activity? Answer. Answer: Even though it is full of liquid water, there is no room for the water to slosh around, so the distribution of mass within the bottle remains the same, and its angular velocity stays constant. What prevents a bottle […]
Where is most marine life?
Where is most marine life? Ocean habitats can be divided into two: coastal and open ocean habitats. Most ocean life can be found in coastal habitats on the continental shelf, even if this area occupies only 7% of the total ocean area. Most of the open ocean habitats are found in the deep ocean beyond […]
