WebAn extinction event (also known as a mass extinction or biotic crisis) is a widespread and rapid decrease in the biodiversity on Earth.Such an event is identified by a sharp change in the diversity and abundance of multicellular organisms.It occurs when the rate of extinction increases with respect to the background extinction rate and the rate of speciation. WebThe water cycle, or hydrologic cycle, is driven by the Sun’s energy. The sun warms the ocean surface and other surface water, causing liquid water to evaporate and ice to sublime—turn directly from a solid to a gas. These sun-driven processes move water into the atmosphere in the form of water vapor. Over time, water vapor in the atmosphere ...

WebThe key concept of exponential growth is that the population growth rate —the number of organisms added in each generation—increases as the population gets larger. And the results can be dramatic: after 1 1 day ( 24 24 cycles of division), our bacterial population would have grown from 1000 1000 to over 16 16 billion!

The troposphere is the layer of the Earth’s atmosphere that humans live and breathe in. The troposphere starts at ground level and extends to 10 kilometers in altitude.
