What is the shore face along a beach? What is littoral drift (long shore sediment transport)? What is difference between Groin and Jetty? Where would you find a tidal inlet? Give an example. What is wave refraction? Identify and describe a barrier island system. What is difference between an estuary and ocean area?
A beach is a land formation along the ocean's shoreline. A shore face is a zone where the water line is lower. Littoral drift is when non-sedimentary sediment (i.e. sand) is moved along the coastline. Groins are structures that run parallel to the cost line. While Jetties, are structures built to stabilize inlets. Tidal inlets are found in between barrier islands. An example of this can be seen when someone is traveling among the Hawaiian Islands. A wave refraction is when a wave is changing its direction. Barrier islands are narrow strips of land that will run parallel to the coastline. An estuary is when fresh water sources are meeting the ocean (i.e. The mouth of a river). The difference between this area; is there are lower amounts of salt and high levels of silt / debris.

Geological Organizations: What is the USGS? What are 3 of their main areas of responsibility or focus? What is the Maryland Geological Survey? What are three areas of A the Maryland Geological Surveys focus? What is the AGI (American Geological Institute)? What is its focus?
The USGS is a government agency that is focused on studying the natural features inside the U.S. Their three areas of responsibility include: analyzing the biology, geology, geography and hydrology of the land. The Maryland Geological Survey is focused on these areas within the state of Maryland. Its three responsibilities are: the biology, geology, geography and hydrology of the land within the state. The AGI is non-profit organization of 45 geo- scientific and professional associations. Their focus is: to serve as a voice for the scientific community, to strength geoscience education and increase public awareness in these areas.

Stratigraphy & Structural Geology: What is stratigraphy? LIST...
Alaska is experiencing a tourist boom of those who want to see glaciers before they disappear. One Hostel in Switzerland is welcoming up to 800 people per day, twice their normal capacity. The guests hope to watch a rock the size of two Empire State Buildings collapse onto a canyon floor about 650 feet below when the glacier which is holding it up finally melts. Meanwhile, they watch boulders
ocean pollution, and how it is affecting marine life. It will also look at what is being done to control pollution in the United States and around the world. OCEAN POLLUTION AND ITS EFFECTS There are numerous pollutants contaminating the world's oceans - they have been building up for hundreds of years, and they are both man-made and natural, although man-made pollutants are much more common than natural pollutants. Over 900,000
Besides the deaths, more than one million people were left homeless and hundreds of thousands homes and businesses were destroyed. The United Nations estimated that, "...the disaster will prove to be the costliest ever recorded, with full economic recovery not expected for up to 10 years in many areas. " (Intute: Science, engineering and technology: Tsunamis) The physical structure of the coast and the environment was severely damaged which meant that
LANDFORMS Barrier island beaches generally develop where: a The coast is composed of hard rock b the nearby land has a rugged topography of hills and mountains c the sea floor deepens rapidly offshore d The sea floor remains shallow for a long distance offshore During storms in winter: a There is a higher percentage of fine-grained sand on beaches b More erosion occurs in bays than on headlands c Beaches are eroded d Beaches are
Weathering is a process that happens to surface rocks based on the particular environment in which the rock is located. The two types of weathering are physical and chemical. Chemical weather is a process in which the internal crystals of rocks undergo chemical changes based on environmental conditions. If rock is exposed to water over a long period of time, for instance, it breaks down and often sand and clay
Geology (1) Discuss which of the interrelationships between the environmental spheres, in your experience, has had the biggest effect on human society, or vice versa. Give some examples. The work of Manahan (2005) explains that there are four traditional environmental spheres including the hydrosphere, atmosphere, geosphere and the biosphere. It is related however, that a fifth sphere should be included and that is the anthrosphere, which consists of "the things humans make
