Geology 1
an elevated region along the ocean floor at the boundary between two diverging tectonic plates
What is the ocean ridge?
the main cause of erosion
What is water?
includes all the elements of Earth's crust, from mountains to the ocean ridge to bodies of water
What are geological features?
This process occurs after weathering.
What is erosion?
a slow-moving mass of ice
What is a glacier?
This process is how beaches and deltas are formed.
What is deposition?
a sand hill or sand ridge formed by wind
What is a sand dune?
This is caused by water, ice, chemicals, and plant roots
What is weathering?
the area of sand or gravel that covers the shoreline from the lower water edge to a well-defined upper elevation
What is a beach?
the two sub-layers of Earth's crust that float, move, and fracture, sometimes causing earthquakes, mountains, volcanoes, and the oceanic trenches
What are the tectonic plates?
the outermost layer of Earth that includes all dry land as well as the ocean floor
What is the crust?
the area positioned at the end of a river (adjacent to an ocean, sea or lake), characterized by the river dividing in a number of streams
What is a delta
a crack in the Earth's crust resulting from the displacement of one side with respect to the other
What is a fault?
the process by which soil and rock are removed from the Earth's surface by natural processes, such as wind or water flow, and then transported to another location
What is erosion?
dropping of sediment by water, wind, and ice
What is deposition?
This process is caused by wind, water, and moving/melting ice.
What is erosion?
the largest delta system in the United States
What is Mississippi River delta?
This process occurs prior to erosion.
What is weathering?
a valley or ravine formed by a river through the process of erosion
What is a canyon?
This is the largest and most famous evidence in the United States of river water erosion.
What is the Grand Canyon?
a mass of ice and snow that permanently covers a large area of land
What is an ice cap?
the slow wearing away of rock into smaller pieces
What is weathering?
a shallow extension of a landmass, which extends outward to the ocean floor
What is the continental shelf?
an area of highland, usually consisting of relatively flat terrain
What is a plateau?
Landslides, earthquakes, floods, volcanic eruptions, tsunamis, and natural disasters are examples of this.
What are fast changes to Earth's surface?
