Ocean Planet
Featured on
An artist's concept shows what Mars might have looked like about 2 billion years ago, when a large ocean might have covered almost half of the planet.
Oceanus Procellarum, Latin for "Ocean of Storms", is a vast lunar mare on the western edge of the near side of Earth's Moon. Its name derives from the old superstition that its appearance during the second quarter heralded bad weather.

Ocean tides
The tides which we see in the oceans are due to the pull of the Moon and the Sun.
Oceanic islands have bizarre flora and fauna: Missing or impoverished in many types of animals.
Missing animals do spectacularly well when introduced by humans.
Islands have "radiations" of an ancestral species.
Ocean tides
Earth's ocean tides are initiated by the tidal force (a gradient in intensity) of Moon's gravity and are magnified by a host of effects in Earth's oceans.

OCEANIC PLATES
The crust of the Earth is broken into plates. The plates are enormous chunks of rock that float atop the soft mantle. The plates are moving at a speed that has been estimated at 1 to 10 cm per year.
Oceans cover 71% of the Earth's surface. It is from these waters that life first emerged, which in turn, it is theorized, was brought to the waters by asteroids during the early days of the solar system.

Oceanic impacts can be considerably more damaging than those on land. Large objects will invariably penetrate or displace the water to impact the seabed, causing huge tsunamis over a large area.

The Oceanic crust is the thinner of the two, only about 5 km thick. It is made up of mainly basaltic rocks. We'll be running into a lot of basaltic rocks, and you probably know these best as the stuff that comes out of volcanoes - lava, basically.
Deep ocean vents are essentially geysers on the ocean floor and are associated with areas of active seafloor spreading. Spewing hot, mineral-rich material into the frigid, surrounding water, such vents are known to harbor bacterial life.
Earth's oceans undergo the greatest deformation because liquid can most easily move around on our planet's surface.

Blame the oceans, which heat up and cool down only slowly. By June 21 they are still cool from the winter time, and that delays the peak heat by about a month and a half.

oceanus literally "ocean"; really a large circular plain old a planetary surface that has been modified little since its formation typically featuring large numbers of impact craters (compare young).
This tremendous ocean however, has no surface. That is because at this layer, hydrogen reaches what is known as its "critical point," at which time the hydrogen gas is the same density as liquid hydrogen, and the two are indistinguishable.

Eridanus, the River, the embodiment of the Greek's "River Ocean," unlike real rivers has two ends. It now terminates in the brilliant first magnitude star Achernar (Alpha Eridani), the name from an Arabic phrase that means "the end of the river.
In 1856 William Ferrel showed that the action of the moon on the ocean tidal waves would result in a retardation of the earth's rotation, a result, at first unnoticed, which was independently reached a few years later by Delaunay.
After the first stage detached, falling into the Atlantic Ocean, the second stage took the craft to 115 miles (185 km) above sea level, with a thrust of one million pounds, at speeds over 15,000 mph (25,000 kph).

The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came.
Ancient observers of the moon believed that the dark regions on its face were oceans, giving rise to the Latin name mare ("sea"), which is still used today; the brighter regions were likewise held to be continents.
About one-third of the solar energy that reaches the surface of the Earth is expended on evaporating ocean water. The resulting atmospheric moisture and humidity condense into clouds, rain, snow, and dew.
Other large telescopes have also been built on mountains on the west coast of California and on the Canary Islands in the Atlantic Ocean. These sites share some common factors.

When Hera saw Callisto glittering with the stars she furiously went down to the ocean to meet Thethys and Oceanos. She told them the story and ask a favour: that the bear never ever is able to reach the water.
The gravitational attraction between the Earth and the Moon gives rise to the lunar tides in the ocean. Because the oceans are fluid, along the radial line from the Earth to the Moon they contain two bulges caused by the attraction.
The outlines of the continents bordering the Atlantic Ocean are so similar that many probably noticed the correspondence, and some might have drawn the conclusion that the lands on both sides were once joined together.
They also understood that if there was some way to determine the difference between high noon in England and high noon in China or in the middle of the Pacific Ocean they could determine their longitude - exactly how far east or west they are.
The Moon's gravitation acts upon the Earth's oceans and atmosphere, causing two bulges to form. The bulge on the side of Earth that faces the moon is caused by the proximity of the moon and its relatively stronger gravitational pull on that side.
It is somewhat surprising to find liquid oceans so far away from the heat of the sun and hidden below thick layers of ice, but similar things happen on earth. Lake Vostok is found under hundreds of metres of ice in antarctica.
Halley sailed to the island of St Helena in the south Atlantic Ocean in 1676 to observe the southern stars.
The ocean tides are an obvious effect of the Moon's gravity but the Moon causes "land tides" to occur too. As the Moon passes overhead the Earth rises towards it by several centimeters and then drops down again as the Moon moves on.
Besides giving us the more mundane information such as the names of countries, oceans, and so forth, a well-labeled globe can serve as our tour guide as we ride our whirling planet through its orbit around the sun.
One spacecraft fell into the ocean during a launch accident. The RTG was recovered from the ocean floor with no escape of , and it was later re-used. Apollo 13's lunar module was carrying an RTG.
The dark Martian surface markings, called "maria" or "albedo features," were once thought by some astronomers to be great lakes, oceans, or vegetation, but space probes in the 1970's revealed them to be vast expanses of rock and dust.
Jupiter's icy moon Europa almost certainly has a liquid water ocean beneath the surface even though its five times further from the Sun than we are.
