All seas and oceans of the world have tides. There are exceptions; these are inland seas and the European Mediterranean Sea. Tides are created by the gravitational effects of the moon and sun. Inland seas have nowhere for the water to flow during these gravitational...

What is the origin of the life on this planet? That is certainly an important question, and one that’s very difficult to answer. An equally important, yet slightly less difficult, question to answer concerns the origin of the single most important substance to the...
The Sunda Trench and predicting the next big earthquake
By: Donna Hicks
The Sunda Trench is part of the Pacific “Ring of Fire” of earthquake activity. Located in the Indian Ocean, the Sunda Trench has successfully given researchers some clues to earthquake predictions and may be able to help predict the next big earthquake. Basic information...

Humans impact coastal zones more than they ever think. Building on the sand, or putting up walls to try to prevent flooding puts considerable strain on the coastal areas. Uses the beach and walking on the grasses thins them but also disperses the seeds so...

A tsunami is a massive wave produced by the sudden displacement of a large volume of water. It increases in height where the sea becomes shallower or narrower, such as many harbors. They are most commonly associated with subduction earthquakes, but can also have other...

In temperate lakes, seasonal changes occur in temperature and density. The area includes most areas in North America, Europe and Asia along with the very tips of South America, Africa and Australia. These areas experience milder seasonal changes in temperature. Temperate lakes have three layers:...

There are really two basic types of aquatic zones, or biomes: marine and freshwater. These two biomes are divided even further into smaller zones. While the marine biome carries a higher salinity content than the freshwater biome, both biomes support a wide variety of plant...

Three main life zones exist in freshwater: the epilimnion, the hypolimnion and the thermocline. The epilimnion is a shallow area where small fish, marine animals and plants, and amphibians live. The hypolimnion is deep water where fish live. Plants do not live well here. Thermocline...

For centuries, people have drawn a connection between the orbit of the moon and ocean tides. As the moon completes its monthly orbit around the Earth, it rises about 50 minutes later each day. Not coincidentally, the times of high and low tide also shift...

The ocean is divided into two main aquatic life zones: the pelagic and the benthic zones. Both of these life zones can sustain life. The vertical dimension of an aquatic system is known as the water column. The physical characteristics comprising a water column include...
