Night and day are determined by the Sun's presence or absence in the sky. As Earth rotates, the portion of the planet that is illuminated by the Sun experiences day while the portion that faces away from the Sun experiences night. As observed from most locations on Earth, the Sun appears to rise in the east and set in the west every day. This video segment features time-lapse photography of a sunrise ... Full description.

Most planetary scientists expected that lunar samples brought to back to Earth by the six Apollo missions would confirm one of three leading hypotheses of the Moon's origin. Instead, the samples left all three explanations unconfirmed, requiring the development of a new hypothesis for how the Moon formed. This video segment shows Apollo 15 astronauts collecting a type of rock (anorthosite) that is ... Full description.

Ocean basins are filled with loose sediments, which are the products of erosion. This sediment originates inland and is fed into oceans by rivers. Debris from cliffs and other coastal landforms provides additional sediment volume, as do skeletons, shells, teeth of marine organisms, ash from volcanoes, and even asteroids. This interactive feature shows how these different parent materials influence ... Full description.

This demonstration of plate tectonic principles, plate boundary interactions, and the geometry and relative motions of faulting of geologic layers uses 3-D foam models. The models aid in visualization and understanding of plate motions and faulting because they are three-dimensional, concrete rather than abstract descriptions or diagrams, can be manipulated by the instructor and the students, and ...

This site provides a brief overview of the earth's climate, which is generally defined as the average weather over a long period of time. The climate of a region is determined by both natural and anthropogenic (human-made) factors. The natural elements include the atmosphere, geosphere, hydrosphere, and biosphere, while the human factors can include land and resource uses. Changes in any of these ... Full description.
