Below the surface there is hard saline water.

The sub surface of Earth contains a vast biodiversity.

The hands shall be brought back on or under the surface of the water.

Now we know where we need to cut, even when it's below the surface.

Sub surface water on Mars, frozen in the form of ice.

In vascular plants, the root is the organ of a plant that typically lies below the surface of the soil.

The water cycle, is the continuous movement of water on, above, and below the surface of the Earth.

At this point the gas will condense at the same rate as the liquid evaporates.

Igneous rock may form with or without crystallization, either below the surface as intrusive (plutonic) rocks or on the surface as extrusive (volcanic) rocks.

The temperature at the surface is some 350 degrees below zero Fahrenheit.

Maybe there's a kind of below the surface, quiet riot that animates us all the time.

Air masses cover many hundreds or thousands of square miles, and adopt the characteristics of the surface below them.

Because on Earth, almost all 99.9 percent of the methane is produced by living systems, not little green men, but microscopic life below the surface or at the surface.

We actually drilled holes into the ice, way deep down below the thawing level, and had some cameras out there for the past month and a half or so.

To make matters worse, the earthquake was barely 6 miles (10 km) undeground making the damage that much worse.

Convective zone In the Sun's outer layer, from its surface to approximately 200,000 km below (70 of the solar radius from the center), the temperature is lower than in the radiative zone and heavier atoms are not fully ionized.

We are seeing geysers of ice which are coming out of that planet, which indicate that most likely there is an ocean, you know, below the surface.

In order to access these sub surface environments that we're interested in, we're very interested in developing the tools to do this.

In addition, some surfaces are made to be porous, allowing the water to drain through the surface to the aquifer below.

The gas at shallow levels (low pressure) forms by anaerobic decay of organic matter and reworked methane from deep under the Earth's surface.

Energy from the Sun heats this layer, and the surface below, causing expansion of the air.

Surface winds below the jet may sway vegetation but are significantly weaker.

The stability of an air mass may be shown using a third letter, either k (air mass colder than the surface below it) or w (air mass warmer than the surface below it).

Lying just beneath the surface of those arguments, with passions raging on all sides, are big questions of moral philosophy, big questions of justice.

The next time that global imbalances develop, analysts will we must hope know to look beneath their surface.

And speed of activity, which is something that we face in our work with sub surface organisms, because they grow very, very slowly.

One of the problems with this, even for surgeons who've been looking at this a lot, is you can't see the cancer, especially when it's hidden below the surface.

So, to find strong evidence of liquid, pools of liquid, beneath the surface of a moon 750 million miles away from the Earth is really quite astounding.

The purpose was to make a crater to excavate the material and see what was underneath the surface of this comet, which we learned quite a bit about.

One of the burning questions, of course, is if we go there and find life in the sub surface, as I fully expect that we will, is that a second genesis of life?

The mesopelagic (Greek μέσον, middle) (also known as the middle pelagic or twilight zone ) is that part of the pelagic zone that extends from a depth of 200 to 1000 metres ( 660 to 3300 feet) below the ocean surface.

SHARAD (radar) MRO's Shallow Subsurface Radar (SHARAD) experiment is designed to probe the internal structure of the Martian polar ice caps.

But the organisms that we work with, from the sub surface of Earth, very often it's months and in many cases, years before we see any growth whatsoever.

It adds roughness to the dune's surface, to the texture of the dune's surface, binding the grains.

The bathyal zone or bathypelagic from Greek βαθύς (bathýs), deep (also known as midnight zone) is the part of the pelagic zone that extends from a depth of 1000 to 4000 metres (3300 to 13000 feet) below the ocean surface.

The lateral facets are pyramid cells, each constructed by one face of the base polyhedron and the apex.

Underneath the right lobe and to the right of the gallbladder fossa, are two impressions, one behind the other and separated by a ridge.

We need to see beyond the surface.

Surface geology Much of the Venusian surface appears to have been shaped by volcanic activity.

It was found that the surface of comet Borrelly is hot and dry, with a temperature of between , and extremely dark, suggesting that the ice has been removed by solar heating and maturation, or is hidden by the soot like material that covers Borrelly's.

This means that the more finely divided a solid or liquid reactant the greater its surface area per unit volume and the more contact it with the other reactant, thus the faster the reaction.

The advent of surface to air missiles and surface to surface missiles, such as the Exocet, in the early 1960s changed naval warfare.

They are surface feeders and prefer to take food in the upper parts of the water column.

Now this is a map, down in the surface of the brain, in which, in a very elaborate experiment we've reconstructed the responses, location by location, in a highly detailed response mapping of the responses of its neurons.

So it's to look beyond the surface.
