Name a pioneer species that would most likely begin primary succession. Mosses and lichens

In which layer of the atmosphere would we find the ozone layer?

Name and describe each stage of the hydrologic cycle. Condensation Precipitation Evaporation

Which transfer of thermal energy? Touching a hot pan A. conduction B. convection C. radiation D. condensation conduction

Name the layers of the atmosphere in order from earth’s surface to space. Troposphere Stratosphere Mesosphere Thermosphere

What is one way that earth’s atmosphere protects or supports life? The troposphere provides the air we breathe. The troposphere has greenhouse gases that keep us from freezing at night. The stratosphere holds the ozone layer that blocks most ultraviolet radiation. The mesosphere prevents most meteoroids from hitting Earth’s surface.
