Microlites are crystal formations that are classifications of Tektites. Tektites are multicolor matter that is the result of terrestrial materials being ejected via extraterrestrial impact. Though somewhat similar to obsidian, their glass exterior makes them distinct. Micrometer size Tektites are known as microtekites.
What is the name of ocean crust?
The name of the crust beneath the oceans is called "oceanic crust." It is thinner and younger than continental crust and primarily composed of basaltic rocks.
How is density related to convection currents?
Put simply things that are of lower density will float on things that have a higher density.
If you take a fluid (i.e. air or water) and heat it, the portion that is heated usually expands. The same mass takes up more volume and as a consequence the heated portion becomes less dense than the portion that is not heated.
The heated portion therefore floats upwards and this portion has to be replaced by colder fluid as it does so.
This flow is called convection, it is an effect of density variations and the driving energy for the movement is heat.
Which current warms the eastern seacoast of the United States?
The Gulf Stream current warms the eastern seacoast of the United States by bringing warm water from the Gulf of Mexico up along the coast. This current helps moderate temperatures and is responsible for the milder climate compared to other areas at similar latitudes.
Where does oceanic continental convergence occur country state continent?
Oceanic-continental convergence occurs in regions where an oceanic plate is subducting beneath a continental plate. Examples of this type of convergence can be found in various locations around the world, such as along the west coast of South America in countries like Chile, Peru, and Ecuador, as well as in regions like the Andes Mountains.
What is the largest volcano in Spain?
The largest volcanic mountain located in the country of Spain is Mount Teide, in Spanish 'Pico del Teide'. It has an elevation of 3,718 meters, of 12,198 ft., which converts it in the highest peak of Spain and also the highest point of the islands of the Atlantic.
Where does river water originate?
River water typically originates from precipitation in the form of rain or snow, which falls onto the ground and then either flows over the land surface or infiltrates into the ground as groundwater. This water eventually makes its way into rivers through runoff or groundwater discharge.
While there are more than four oceans on Earth, there are four which are considered the main ones. The four main oceans are the Pacific, Atlantic, Indian, and Arctic.
Ocean currents reverse in the winter compared to the summer because of changes in temperature and wind patterns. During the summer, warmer water and prevailing winds create specific currents, whereas in the winter, colder temperatures and changing wind directions lead to a reversal in the flow of currents.
How are the north equatorial and south equatorial currents in the pacific ocean alike and different?
The North Equatorial Current and South Equatorial Current in the Pacific Ocean are both warm, fast-moving currents that flow towards the west. They are driven by the trade winds. One key difference is that the North Equatorial Current is influenced by the North Pacific Gyre, while the South Equatorial Current is influenced by the South Pacific Gyre.
What did Matthew Fontaine Maury do?
Matthew Fontaine Maury compiled and standardized the wind and current data recorded in the US Navy ship logs and summarized his findings in the Physical Geography of the sea.
----------------
Not just the US Navy but Internationally. He headed the first International Conference of Nations for this work.
Too, he accomplished many other things.
See wikipedia and other encyclopedias.
The moon's gravitational pull on Earth causes the ocean tides. The gravitational force creates a "stretching" effect on the Earth, with tides occurring as the Earth rotates within the "bulge" of water created by the moon's gravity.
How long ago was Florida underwater?
Before the earth was finished forming all of its land masses, Florida was under water. There are still several parts of Florida that are under water. The Everglades is covered in water.
Questions for hurricanes what was the costliest hurricane in the US?
The costliest hurricane in U.S. history was Hurricane Katrina in 2005 with an estimated 81.2 billion dollars in damages.
In what season do ponds and lakes turn over?
Ponds and lakes typically undergo turnover in the fall and spring. In the fall, cooling surface waters sink and mix with deeper, oxygen-rich waters. In the spring, warming surface waters mix with cooler, nutrient-rich waters.

What is a macrotidal and microtidal estuary?
A macrotidal estuary experiences large tidal variations, with significant differences between high and low tide levels. In contrast, a microtidal estuary has smaller tidal variations, with minimal differences between high and low tide levels. These tidal ranges affect factors such as sediment transport, water circulation, and ecosystem dynamics within estuarine environments.
A seamount is an underwater mountain rising from the ocean floor that does not reach the water's surface. These geological features are formed by volcanic activity and can be found throughout the world's oceans. They provide important habitats for a variety of marine life.
Why are large areas of sea floor covered with thick layers of sediment containing calcium?
Large areas of sea floor are covered with thick layers of sediment containing calcium due to the accumulation of calcium carbonate shells and skeletons from marine organisms over time. This process, known as biomineralization, contributes to the formation of limestone and other calcium-rich sediments.
What is the coral reef energy pyramid?
The coral reef energy pyramid represents the flow of energy through different trophic levels in a coral reef ecosystem. At the base of the pyramid are primary producers like algae and phytoplankton, followed by primary consumers like herbivorous fish, then secondary consumers like carnivorous fish, and finally top predators like sharks. Each level transfers energy from one trophic level to the next, with energy decreasing as it moves up the pyramid.
What is the length of the Gorge at Niagara Falls?
The Niagara Gorge is approximately 11 kilometers (7 miles) long, stretching from Niagara Falls to the Niagara River Whirlpool.
