Verbs

Clear is already a verb.
Other verbs depending on the tense are clears, clearing and cleared.

Some examples are:
"I will clear the way".
"She clears her room".
"He was clearing out the shed".
"We cleared the gutters".

"Science" is a noun. It refers to the systematically organized body of knowledge on a particular subject.

Biology is the study of living organisms and their interactions with each other and their environment.

The verb "squeeze" means to press in opposite forces, such as with two hands.

There are two theories: biological origin (currently the dominant theory) and non-biological (not widely accepted in the scientific community, but with some good points to it). From Wikipedia ( http://en.wikipedia.org/wiki/Petroleum#F... ):

Biogenic theory

Most geologists view crude oil, like coal and natural gas, as the product of compression and heating of ancient organic materials over geological time. According to this theory, oil is formed from the preserved remains of prehistoric zooplankton and algae which have been settled to the sea bottom in large quantities under anoxic conditions. (Terrestrial plants tend to form coal, and very few dinosaurs have been converted into oil.) Over geological time this organic matter, mixed with mud, is buried under heavy layers of sediment. The resulting high levels of heat and pressure cause the remains to metamorphose, first into a waxy material known as kerogen which is found in various oil shales around the world, and then with more heat into liquid and gaseous hydrocarbons in a process known as catagenesis. Because most hydrocarbons are lighter than rock or water, these sometimes migrate upward through adjacent rock layers until they become trapped beneath impermeable rocks, within porous rocks called reservoirs. Concentration of hydrocarbons in a trap forms an oil field, from which the liquid can be extracted by drilling and pumping.

Geologists often refer to an "oil window" which is the temperature range that oil forms in-below the minimum temperature oil remains trapped in the form of kerogen, and above the maximum temperature the oil is converted to natural gas through the process of thermal cracking. Though this happens at different depths in different locations around the world, a 'typical' depth for the oil window might be 4-6 km. Note that even if oil is formed at extreme depths, it may be trapped at much shallower depths, even if it is not formed there. (In the case of the Athabasca Oil Sands, it is found right at the surface.) Three conditions must be present for oil reservoirs to form: first, a source rock rich in organic material buried deep enough for subterranean heat to cook it into oil; second, a porous and permeable reservoir rock for it to accumulate in; and last a cap rock (seal) that prevents it from escaping to the surface.

If an oil well were to run dry and be capped, it would be back to original supply rates eventually. There is considerable question about how long this would take. Some formations appear to have a regeneration time of decades. Majority opinion is that oil is being formed at less than 1% of the current consumption rate.

The vast majority of oil that has been produced by the earth has long ago escaped to the surface and been biodegraded by oil-eating bacteria. What oil companies are looking for is the small fraction that has been trapped by this rare combination of circumstances. Oil sands are reservoirs of partially biodegraded oil still in the process of escaping, but contain so much migrating oil that, although most of it has escaped, vast amounts are still present - more than can be found in conventional oil reservoirs. On the other hand, oil shales are source rocks that have never been buried deep enough to convert their trapped kerogen into oil.

The reactions that produce oil and natural gas are often modeled as first order breakdown reactions, where kerogen is broken down to oil and natural gas by a set of parallel reactions, and oil eventually breaks down to natural gas by another set of reactions. The first set was originally patented in 1694 under British Crown Patent No. 330 covering "a way to extract and make great quantityes of pitch, tarr, and oyle out of a sort of stone." The latter set is regularly used in petrochemical plants and oil refineries.

Abiogenic theory

Main article: Abiogenic petroleum origin

The idea of abiogenic petroleum origin was championed in the Western world by astronomer Thomas Gold based on thoughts from Russia, mainly on studies of Nikolai Kudryavtsev. The idea proposes that large amounts of carbon exist naturally in the planet, some in the form of hydrocarbons. Hydrocarbons are less dense than aqueous pore fluids, and migrate upward through deep fracture networks. Thermophilic, rock-dwelling microbial life-forms are in part responsible for the biomarkers found in petroleum.

However, this theory is very much a minority opinion, especially amongst western geologists. It often pops up when scientists are not able to explain apparent oil inflows into certain oil reservoirs. However, most of these "abiotic" fields are explained as being the result of geologic quirks. No western oil companies are currently known to explore for oil based on this theory.

Yes, "barometer" is a noun in the dictionary. It refers to an instrument that measures atmospheric pressure.

According to Dictionary.com the definitionof photosynthesize is performing the process of photosynthesis. And the definition of photosynthesis is below...however there realy is no common synonym for photosynthesize. pho·to·syn·the·sis

-noun Biology, Biochemistry. (esp. in plants) the synthesis of complex organic materials, esp. carbohydrates, from carbon dioxide, water, and inorganic salts, using sunlight as the source of energy and with the aid of chlorophyll and associated pigments.

usually a word related to the moon would be lunar. an xample would be the lunar eclipse.

No, Vesuvius is not a verb. It is a noun referring to a volcano located in Italy.

The ablative of means is used to describe the instrument or tool with which the action is performed. It answers the question "with what" something is done. This ablative form often uses prepositions like "cum" meaning "with" for this purpose.

Yes, it's a word for the act of squeezing, such as to squeeze a lemon.

The compound verb in the sentence is "pick up," which consists of the two verbs "pick" and "up" merged together to form a single action.

Yes, "pressure" can be used as a verb meaning to apply force or influence to someone in order to make them do something. Example: "She pressured me to finish the project on time."

"Shine" is a regular verb in the English language. It follows standard conjugation rules for regular verbs in terms of forming its past tense ("shone") and past participle ("shone").

The verb for adhesion is "adhere."

"Smelled" is a verb, but it is a linking verb when used to express the sense of smell. It connects the subject to the sensory experience rather than describing an action.

Yes, example: he blasted the rusty metal with sand.

The verb of sensation is "to feel." It is used to describe the action of experiencing a physical or emotional sensation through touch, sight, hearing, taste, or smell.

The verb in the sentence "I'll never understand physics" is "understand."

"Fresh" can be both a noun and an adjective. As a noun, it typically refers to food that has not been processed or preserved. As an adjective, it describes something new or recently made.

"Weight" can be a noun or a verb. As a noun, it refers to the measurement of how heavy an object is. As a verb, it means to measure the heaviness of an object.

The verb form of "glass" is "glasses." For example, "I will glass the windows" means to cover or repair with glass.
