The 4 stages of the Wilson cycle describes the birth and death of an ocean. these stages are embryonic, juvenile, mature, decreasing, terminal, and suturing.
The tectonic movement of the Earth causes the periodic opening and closure of ocean basins. A rising plume of magma and crustal weakness initiate the Wilson cycle. The Wilson cycle is named after J. Tuzo Wilson, a Canadian geophysicist. One of the most essential interpretations of current plate tectonics and the Wilson cycle is that all other rocks on the planet may be created from a parent igneous rock of mafic/ultramafic composition.
Sediments build near ocean basin borders when the crust thins owing to extensional tectonic processes. Subduction then occurs on one of the ocean basin's boundaries, narrowing the basin. A fresh cycle begins when the crust begins to thin again.

The site on the surface of a reactant or substrate where it binds to the enzyme is called the:_____.
The site on the surface of a reactant or substrate where it binds to the enzyme is called the active site.
The active site or catalytic site is the specific site of an enzyme where substrates bind. Structural complementarity between E and S allows for exact matches. Enzymes adapt to their substrates through a conformational change known as induced adaptation.
Substrate and active site are two terms used for catalytic reactions involving an enzyme as the catalyst. The difference between the substrate and the active site is that the active site is a specific region of the enzyme whereas the substrate is the chemical compound that can undergo a chemical reaction.

How does the spacing of the contour lines show the difference between gentle and steep slopes?
Where slopes are steep, contour lines are closely spaced.
The slope is determined by the distance between contour lines; the greater the distance, the softer the slope.

This type of synovial joint has two flat bone surfaces that allows for the bones to slide over one another creating tiny movement in all directions. this joint is called gliding joint.
What is synovial joint?The joints of the limbs and other bones that rub up against one another are examples of synovial joints (e.g. shoulder, hip, elbow and knee). Its distinguishing feature is a joint cavity filled with fluid.Synovial joints enable motion. A thin layer of tough, smooth articular cartilage covers the surfaces of the bones where they come together to form a synovial joint. A very thin coating of synovial fluid, a slippery, viscous joint fluid, separates and lubricates the two sides of the two cartilage-covered bones. What is gliding joint?When two bones come together at flat or nearly flat articular surfaces, they produce a gliding joint, sometimes referred to as a plane joint or planar joint.

A fault that accommodates the horizontal movement of one tectonic plate past another is a(n) __________ fault.
A fault that accommodates the horizontal movement of one tectonic plate past another is a transform fault.
An example of a transform fault is a strike-slip fault where the relative horizontal slip allows movement to occur between two tectonic limits, such as two ocean ridges. They are linked to other defects on both ends.
Since these faults neither build nor destroy lithosphere, they are sometimes known as transform faults or transform boundaries, and their relative motion is primarily horizontal. A transform fault allows for some horizontal relative movement between other tectonic components, like oceanic plates.

A lake that has been affected by acid rain can have a ph of 4. how many more times acidic is the lake than seawater?
A lake that has been affected by acid rain can have a ph of 4. so the lake is 10,000 times acidic than seawater
Seawater has a pH of 8, so there's a difference of 4 pH units, so there's a difference in hydrogen ion concentration of 10^4.
here Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions. Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on averageAcid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air.

The NIST-F1 Cesium fountain clock is in Colorado. It is the standard for primary time and frequency in measuring time.
The NIST laboratories in Boulder, Colorado, developed the cesium fountain atomic clock NIST-F1, which serves as the country's primary time and frequency standard. NIST-F1 is a member of the global network of atomic clocks that establishes Coordinated Universal Time (UTC), the recognized global time.
The NIST-F1 is known as a fountain clock because it measures frequency and time intervals by using the atoms' fountain-like movement. Atomic clocks are the most precise means of measuring time intervals, or the amount of time that separates two events.
Atoms in the clocks leap from one energy level to another due to the precise frequency at which these clocks emit electromagnetic radiation, such as microwaves.

Why does the equatorward bending of height contours for the 500 mb level imply the presence of a trough?
The equatorward bending of height contours for the 500 mb level imply the presence of a trough because this represents a region of overall lower heights. A valley and a trough are hence equivalent in the upper air flow.
A trough is a linear structural depression with lateral length that occurs in geology. A trough can be a small basin or a natural rift, albeit it is lower than a trench. At the edge of tectonic plates, these landforms frequently form.
Trough, an extended depression in the seafloor that differs from oceanic trenches in that it is shallower, shorter, narrower, and topographically more mild. The Papuan Trough's maximum depth is 2,300 m (7,500 feet), while the Banda Trough's maximum depth is 7,440 m.

The possibilities of an earthquake of a particular magnitude occuring inside a location over a period of years are referred to as earthquake forecasting. On the basis of the average frequency of previous seismic activity in a region, probabilities can be determined.
Seismographs, which became widely used in the early 1900s, have been used to record earthquakes in areas where this technology is most helpful.

Relative dating involves age-dating fossils with known time periods grouped into four eras that represent distinct ages in the history of the earth.
Relative dating is used to chronologically order geological occurrences and the rocks they leave behind. Relative dating does not give the rocks' precise numerical ages. Even when you locate rocks that are quite far apart but are the same age, fossils can still be used to match them.
Correlation is the term for this matching procedure, which has been crucial in creating geological timescales. Index fossils are specific fossils that are very helpful in connecting rocks.

How did the development of an interstate highway system change the urban landscape in the united states?.
The US interstate highway system destroyed the city's white urban middle class and lower middle-class residential areas.
New "whites only" residential areas were created in low-cost land areas outside urban and suburban employment centers and in formally rural agricultural areas by providing means of economic communication at low (relatively) cost. Those areas are being acquired by land speculators, who have profitably developed them into suburban residential housing subdivisions. With all interregional connectivity and newly built shopping and commercial centers. Before the US interstate highway, even small- to medium-sized cities had dense urban cores, with much of the development geared toward pedestrians and mass transit users. After the interstate, by the 1970s, only a few areas had the density to support pedestrian and mass transit infrastructure until more and more people depended on cars. It's popular now to blame urban areas on freeways. It's just as important to consider that many suburban areas, especially in the Northeast, need new housing developments with 2-5 acre land requirements. Also, many areas across the country have strict zoning requirements that only mandate residential development for miles and miles of land, so no one would walk that far even if they wanted to.
