Altitude is height above sea level. The density of air decreases with height. There are two reasons, at higher altitudes there is less air pushing down from above,and gravity is weaker farther from earths center.
Answer: Seastars prey on mussels and shellfish which would otherwise have no other natural predators. Herbivorous fish like the butterflyfish pictured to the left prey on marine algae. Without this crucial predator-prey balance, the algae would over-grow, which would then kill coral, as they compete for the same resources.
To find the molecular formula of the compound, we get the molar mass of empirical formula CH2o which is 30 g/mol. We divided the molecular mass of 90.087 g/mol by 30, we get 3. Hence, we multiply each element by 3, getting the molecular formula of C3H6O3.
I am pretty sure nitrogen would be the solvent because solvents are generally the larger amount
<span>Hazards from huge explosive eruptions comprise extensive ash-falls with small glass particles in it, pyroclastic flows (combinations of hot gases and pumice chunks), and immense lahars which are volcanic mud flows which can even include debris. These put people within the area in danger. Nearby properties get damaged as well within a circumference of tens to hundreds of miles away from the volcano. These eruptions can extensively cause a change to the global climate too. Hazards from quiet eruptions include lava flows which contain exploding fires and creating gas clouds which are rich in chlorine where lava pours into the sea. This can cause damage to wildlife and sea creatures.</span>
