Any system within the Earth system is considered an open system. Because energy flows freely into and out of systems, all systems respond to inputs and, as a result, have outputs. For example, water and chemicals, as well as energy enter and leave the boundaries of a watershed system. Outputs from one part of the system are inputs for another part. This linked output-input connection is often called ‘feedback’. The inputs and outputs are important for understanding the dynamics of the system you are studying as these are the key for helping us identify one system from another.
Drought conditions have affected much of the U.S. Southwest and Central Plains in recent years. But scientists now believe future droughts in the last half of this century could be the worst in the past millennium.
This activity will help students better understand and practice estimating percent cloud cover.
Students review a video that models the global impact of smoke from fires, to develop an understanding of how models can be used to interpret and forecast phenomenon in the Earth System.
Teachers, these mini lessons/student activities are perfect "warm up" tasks that can be used as a hook, bellringer, exit slip, etc.

Learn about the different cloud types and their names. Match cloud photos and names by cloud type and for all types. Evaluate the types of clouds represented in various data displays.
Watch the NOVA PBS video - The Climate Wild Card about the different effects of clouds on climate and Earth's energy budget.
