Geologic Time: Concepts and Principles

Chapter 4. Geologic Time: Concepts and Principles. Grand Canyon. When looking down into the Grand Canyon, we are really looking at the early history of Earth. Grand Canyon. More than 1 billion years of history are preserved, like pages of a book, in the rock layers of the Grand Canyon

Contaminants and Conservation

Contaminants and Conservation. Contaminant Impacts . Key difficulty for measuring contaminant impacts is that most if not all systems impacted by contaminants are also affected by other human-mediated changes

Sand Dune Formation

Great Lakes Sand Dunes. Largest assemblage of freshwater coastal dunes in the worldGeologically youngOnly 3,000 to 4,000 years old. Sand dunes are divided into different ecological zones. BeachesForedunesInterdunal wetlands or toughsBack Dunes or Dune Forests. Critical factors for sand dune creation:.

Coasts and Reefs: Shallow marine processes

Coastal System. A beach is part of a coastal system, which includes several zones defined by their proximity to shore and the dominant processes that occur within them.. . Offshore to Shoreface. Offshore and shoreface portions of the coastal profile are permanently submerged in water, below the low tide mark.An important feature that separates the offshore from shoreface zones is fairweather wave base
