Here you will find links to a variety of other websites that will help deepen your understanding of content and prepare you for the EarthComm: Earth's Natural Resources module

Here you will find resources to help educators and their students to model and investigate the stability of structures on permafrost; understand some of the problems that permafrost presents for human habitation; be able to describe the interaction between sea ice and climate as an example of a positive feedback loop in Earth systems science; understand some of the important implications of sea ice, icebergs, and frost within the Earth system.

Here you will find resources to help educators and their students to model the effects of ice dam failure and catastrophic flooding; Evaluate the uses and limitations of this type of model in Earth science; Describe how catastrophic glacial floodwaters alter the landscape; Understand that while most geologic events are slow and gradual processes, others can be abrupt; Determine whether catastrophic glacial floods have affected your community in the past or could threaten your community in the future.

Here you will find resources to help educators and their students to understand that glaciers modify the landscape by erosional and depositional processes; Understand that the movement of glaciers can change stream drainage patterns; Model the effects of a glacier infringing on a stream; Evaluate the uses and limitations of this type of model in Earth science; Apply what you have observed to determine if glaciers have affected your community in the past.

Here you will find resources to help educators and their students to model sea level changes using a stream table; Evaluate the uses and limitations of this type of model in Earth science; Describe features of a coastal landscape during a time of rising sea level; Describe features of a coastal landscape during a time of falling sea level; Determine how your community’s landscape would be affected by rising and falling sea levels; Describe ways that sea level changes have affected human history.

Here you will find resources to help educators and their students to estimate how much ice was contained in the Pleistocene glaciers using maps; Use the estimate to calculate how much lower sea level was during the Pleistocene; Estimate the amount of ice in the Greenland and Antarctic ice sheets and calculate how much sea level would rise if they were to melt completely; Determine if sea level changes would affect your community.

Here you will find resources to help educators and their students to make a mathematical model of an imaginary glacier; Evaluate the uses and limitations of this type of model in Earth science; Calculate how the glacier would respond to hypothetical changes in climate.

Here you will find resources to help educators and their students to calculate the time required to melt ice; Graph data to determine a heating curve for ice; Understand that the unique chemical and physical properties of water cause the unusual physical properties of ice.

Here you will find resources to help educators and their students to Construct a map of tornado frequency throughout the United States; Determine from the map the likelihood of a tornado where you live.; Describe the relationship between tornado and thunderstorm distribution across the U.S.; Explain the relationship between tornado frequency and time of the year.; Examine tornado safety procedures to follow while at school, at home, or outside.; Understand that there are misconceptions related to tornado safety.

Here you will find resources to help educators and their students to Interpret data on casualties due to lightning; Describe what causes lightning; Explain the relationship between lightning and thunder; Realize that many myths and misconceptions about lightning can be dangerous; Know what safety precautions need to be taken during any lightning event; Understand that lightning is a process where electrical energy flows between the atmosphere and Earth’s surface or between different clouds.
