Earthquakes occur along faults because they're under pressure.
Faults are cracks in the Earth where the tectonic plates are moving in different directions, thus there is a pressure.
Answer:
Low - The generation of nitrates (NO 3-) requires oxygen, so the oxygen levels will be low
Explanation:
Nitrates are formed when the ammonia react with oxygen present in water. The oxygen which react with ammonia is not the oxygen of water molecule, it is the dissolved oxygen. This oxygen is used by aquatic animals for breathing. If nitrates are formed so the concentration of dissolved oxygen will be lowered which causes suffocation and bad impact on marine organisms and the whole ecosystem will be disturbed.
Answer:
Radioactive dating uses radioactive elements to date matter such as rocks and fossils. As the radioactive elements disintegrate, they turn into other elements. Scientist then use the ratio of the two elements to determine how old something is.
Explanation:
Answer:
Both cones and rods participate in dark adaptation, slowly increasing their sensitivity to light in a dim environment. Cones adapt faster, so the first few minutes of adaptation reflect cone-mediated vision.
