a towering column of ash, gas, and fragmented magma (tephra) is ejected into the atmosphere. When the column becomes too dense or loses upward momentum, it collapses under its own weight. The resulting avalanche
It moves into the soil or into the mainstream water where it then serves as a source of nutrition to living organisms. Apart from these biogenic sources, carbon dioxide is produced from other natural sources such as volcanoes, hot springs, and geysers. Volcanoes, in particular, emit about 0.2...
Volcanoes in the ocean create new islands. B A change in the environment leads to a grassland becoming a forest. C A small group of organisms are washed to sea during a storm and land on a new island. D A change in climate creates a desert that divides a large grassland. ...

One such process, the “solubility pump,” involves the descent of surface seawater containing dissolved CO2. Another process, the “biological pump,” involves the uptake of dissolved CO2 by marine vegetation and phytoplankton (small, free-floating, photosynthetic organisms) living in the upper ...
Density-independent factor is any force that affects the size of a population of living things regardless of the density of the population. They often arise from physical and chemical (rather than biological) phenomena. Examples include weather and clima
