Which statement describes an attribute of an artesian well?
requires a bucket
uses natural pressure
needs a mechanical pump
is heated by hot rocks or magma
Answer:
Uses natural pressure
Explanation:
The geologic conditions necessary for an artesian well are an inclined aquifer sandwiched between impervious rock layers above and below that trap water in it.
Correct option are B and D.
The phenomenon of artesian well is due to the pressurization of an aquifer (natural pressure), when the inclination of the impermeable geological layer which overcomes it forces it below the level of its piezometric line (line of equal pressure of the groundwater).
Since this deep groundwater can be hot, artesian wells are also used in geothermal heating systems.

Describe About Earthquakes answer ASAP for the brainliest
Answer:
Earthquakes are caused by fault lines.
Explanation:
The continents are on massive tectonic plates the are constantly shifting because of the movement of magma underneath them. When the tectonic plates rub against each other, or collide with each other, it creates movement that we know as earthquakes. The reason why we feel earthquakes is because of the sudden energy release which causes seismic waves. One famous fault if the San Andreas fault, located in California. That is the reason why earthquakes are common in California (because it is located right next to a fault line).
Answer:
Explanation:
Earthquakes are rubbed against eachother and can cause lots of damage to the environment and people, the earthquakes in california can be very dangerous and can hurt a lot of people due to the mass population and density

Explain how the angle-angle-side congruence theorem is an extension of the angle-side-angle congruence theorem.
Answer:
The interior angle measures of a triangle add up to 180 degrees. Thus, if you are given angle-angle-side, you can solve for the third angle measure and essentially have angle-side-angle because the given side will now be the included side.
Explanation:
In congruent triangles, 2 angles and the enclosed side of another triangle are equivalent to the similar angles and side of some other triangle, the extension of angle-angle-side.
What is angle-side-angle?The Angle-Side-Angle defines that if 2 consecutive angles as with a non-included side of one triangle are appropriate to the related 2 consecutive angles and the non-included side of the other triangle, then the 2 triangles are congruent.
This congruent triangle is called as the angle-side-angle, and they form, the extension of angle-side-angle congruence theorem.
A triangle is measured by the inferior angle that add up to 180 degrees. Thus, in given angle-angle-side, solve for the 3rd angle measure and fundamentally have angle-side-angle, as the given side will now be the enclosed or included side.
Therefore, it is called as the extension of angle-side-angle congruence theorem.

calculate the longitude of the position of a ship whose navigation office obwerve that Greenwich mean time is 1416 hours when the local time is noon
Answer:
34 degree West
Explanation:
Given
Greenwich Mean Time (GMT) = 14:16 hours
Local Time = Noon = 12:00 hours
Required
Calculate The Longitude of the Ship's position
We start by calculating the time difference;
Time Difference= GMT - Local Time
Time Difference = 14:16 hours - 12:00 hours
Time Difference = 02:16 hours
Convert time difference to minutes
Time Difference = 02:16 hours
Time Difference = 02 hours + 16 minutes
Time Difference = 02 * 60 minutes + 16 minutes
Time Difference = 120 minutes + 16 minutes
Time Difference = 136 minutes
Convert Minutes to degrees
In GMT, 4 minutes it will rotate 1 degrees
So, 136 minutes = 136 degrees / 4
136 minutes = 34 degrees
Hence, the ship is 34 degree West

Why do you think the diagram uses double-headed arrows to represent the exchanges occurring within Earth's
subsystems?
Answer:
They used double headed arrows to express that the exchange could go both ways, not just in one direction.
Explanation:
The diagram uses double-headed arrows to represent the exchanges occurring within Earth's subsystems, which is an open system as energy flows freely out of the system.
What is Earth's subsystems?Everything in the Earth's system may be classified as either land, water, living creatures, or air. These four subsystems are referred to as "spheres." Specifically, these are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).
The earth, based on the diagram, is an open system. Because energy freely flows into and out of systems, all systems respond to inputs and have outputs as a result. Water, chemicals, and energy, for example, enter and exit the limits of a watershed system. Outputs from one area of the system serve as inputs to another. This connected output-input relationship is commonly referred to as 'feedback'.
As a result, the figure employs double-headed arrows to depict the trades that take place inside Earth's subsystems, which is an open system.

In order to withstand tidal currents, juvenile horseshoe crabs frequently burrow in the sand. Such burrowing discourages barnacles from clinging to their shells. When fully grown, however, the crabs can readily withstand tidal currents without burrowing, and thus they acquire substantial populations of barnacles. Surprisingly, in areas where tidal currents are very weak, juvenile horseshoe crabs are found not to have significant barnacle populations, even though they seldom burrow.
Which of the following, if true, most helps to explain the surprising finding?
(A) Tidal currents do not themselves dislodge barnacles from the shells of horseshoe crabs.
(B) Barnacles most readily attach themselves to horseshoe crabs in areas where tidal currents are weakest.
(C) The strength of the tidal currents in a given location varies widely over the course of a day.
(D) A very large barnacle population can significantly decrease the ability of a horseshoe crab to find food.
(E) Until they are fully grown, horseshoe crabs shed their shells and grow new ones several times a year.
Answer:

What is the chemical nature of
oxide of carbon ? Explain with the
help of equation.
Carbon forms two important gases with oxygen: carbon monoxide, CO, and carbon dioxide, CO2. Carbon oxides are important components of the atmosphere, and they are parts of the carbon cycle.
Carbon dioxide is naturally produced by respiration and metabolism, and consumed by plants in their photosynthesis. Since the industrial revolution, greater amount of carbon dioxide has been generated for over a hundred years due to increased industrial activities.
Today, information on carbon oxides is important. Issues related to carbon oxides have no boundaries. The Carbon Dioxide Information Analysis Center (CADIAC) provides global datasets on carbon dioxide and other atmosphere gases and climate. These datasets are available to international researchers, policymakers, managers, and educators to help evaluate complex environmental issues associated with potential climate change.
Carbon monoxide is also a national and global concern. The Consumer Product Safety Commission (CPSC) considers CO a senseless killer, and it provides information on CO poisoning and detection.construc.gif
What are the molecular structures of carbon oxides?
The formation of carbon oxides is due to electronic configurations of carbon and oxygen. They have 4 and 6 valence electrons respectively. Using these valence electrons, we can give the Lewis dot structure for CO and three resonance structures for CO2 as follows:
.. .. .. ..
:C:::O: :O::C::O: « :O:C:::O: « :O:::C:O:
'' ''
These formulas suggest very strong bonding between carbon and oxygen in these gaseous molecules: triple bond in CºO, and double bonds in O=C=O. However, a formula containing a triple bond contribute to the resonance structure.
The chemical bonding is more of an interpretation of the molecules in view of their properties.

Explain how climate can affect travel especially with airplane.
Answer:
various answers
Explanation:
In hot weather, planes can struggle to generate enough lift during take off because warm air is thinner than cool air. Some researchers warn that as the climate changes, cancellations due to high temperatures may become more common.
Every aircraft has a maximum operating temperature, which is set by the manufacturer and approved by regulators. If the air temperature exceeds that limit then planes are not permitted to take off.
Fog, snow, ice and crosswinds mean that air traffic controllers have to increase the gap between planes that are landing, reducing the number of aircraft that an airport can manage. The same weather can make it slower and more difficult for the planes to taxi between runway and terminal building.

calculate the longitude of the position of a ship whose navigation office observe that Greenwich mean time is 1416 hours when the local time is noon
Answer:
Ship is 34° west
Explanation:
given data
mean time is 14:16 hours
local time = noon
solution
as we know that when each degree of shift in the longitude then there will be a time difference of 4 minute
so 1° = 4 minutes
and
given time change in hour
change in hours = 14:16-12:00 = 2 hrs 16 minutes
so time zone at the ship location = 9 hours 20 minutes behind GMT
and
2 hrs 16 minutes = 136 minutes
now we convert to degree so divide by 4
change in degree = [tex]\frac{136}{4}[/tex]
change in degree = 34°
so, ship is 34° west
