The distribution of earthquakes defines the boundaries of which major earth feature

Answers

Answer:

tectonic plates

Explanation:

The earthquakes are in general distributed along the boundaries of the tectonic plates. Some tectonic plate boundaries produce more earthquakes than others, as well as stronger ones.

The reason why the earthquakes are roughly aligned along the tectonic plates boundaries is that those places are the most active geologically. The pressure that is created between the plates is enormous. This pressure manages to create big cracks deep into the crust. Once the crust can not bend anymore, it crumbles, and as it does a gap opens up. The opened up gap is than filled in with other crust from above, thus it is a natural way of adjustment.

When the crust adjusts itself, the force created is enormous. This force creates strong vibrations, which are actually what we call earthquake. The place where the earthquake forms in called the hypocenter, while the place vertically above it on the surface is called the epicenter.

Answers

Answer:

Utah

Explanation:

All the rest of the cities have plenty of nuclear power except for Utah.

Answer:

The best state to avoid the possible dangers of nuclear power is Utah.

Explanation:

The state of Utah, located in the west of the country, is a relatively sparsely populated state, with 2.7 million inhabitants mostly concentrated in Salt Lake City. Within the state there is no nuclear power plant, therefore, the energy is produced by alternative means such as hydroelectric dams, wind and solar energy centers.

Despite this, there is a project for the creation of a nuclear power plant in the state, the Blue Caste Project, which will open a plant in Green River in 2028.

B.Longitude
C.Altitude
D.The scale

Answers

Answer:

A. Elevation

longitude = map lines that are vertical

Altitude = Think planes how high from the ground something is (Elevation is also accounted for)

The scale = a measureing device that is used to find the weight of things.

therefore the best answer is:

A. Elvation - The heights above or below something most especially the sea (sea level)

Hoped this helped :)

Elevation is the measurement used on the sea level to ground level

while altitude is measured the distance from sea level to air level

So if your standing on ground that would be elevation while if your in a plain that would be altitude

Answers

Answer:

global warming

Explanation:

The global warming is believed to be able to affect the global climate through warming it up. It is mostly the emissions of greenhouse gasses that are considered to be responsible for it, such as the carbon dioxide and methane, but in reality it is the natural factors that have the leading role by far.

The releasing of these gasses into the atmosphere by the humans since the Industrial Revolution has caused rise in the amount of these gasses into the atmosphere, rise that is more rapid than the natural increase of it. The world has been in panic lately as it has been noticed that the global temperatures are on the rise, and that it may have catastrophic consequences for the humanity.

In practice though, it turned out that only one of the projections about the climate changes was accurate, that being the Russian model, which was also the least dramatic one, while all the other models were predicting dramatic changes, but that didn't happened. Also, the panic about the catastrophic effects of it are also way to exaggerated, as a global warming, as the geologic evidence shows, will actually make the climate much more equalized, with the extremes in temperatures largely minimized, and having much more wet and green planet. The only real problem is that big portion of the human population will need to be relocated on slightly higher ground as the sea levels will rise.

Explain the causes and effects of the rise of the Islamic states over time

Answers

The Islam emerged in the sixth century AD, and with it, the first Islamic states started to occur. The Islamic states started to occur because this religion managed to unite lot of tribes and create one powerful entity. The military strength was big, so it was used for expansion, and on the territories that were conquered, the people were converted to Islam, very often forcefully. This has resulted in rapid change of the political and religious map of the world, with a very large area becoming dominated by Islam. The Islamic states, once properly established, flourished and were very advanced, having big achievements in numerous scientific fields. Unfortunately, the fundamentalist fraction managed to prevail over time and stopped the progress, so gradually the Islamic states started to fall behind the other parts of the world when it came to development, and that can be seen even nowadays.

B.

C.
oceans absorb heat more slowly, which has a cooling effect on land
D.
oceans absorb heat more quickly, taking heat away from the land

Answers

Answer:

D.  oceans absorb heat more quickly, taking heat away from the land

Explanation:

During summer when heat rises, sea water absorbs heat slowly due to the nature of its heat capacity. The land area around the beaches will warm rapidly. This difference in heat between land area close to the sea and the sea water causes movement of cool sea breeze to move to the land area.

The  reverse is the case during winter. Land area in winter loses heat rapidly and therefore, they cool while the sea becomes warm as it does not lose heat easily. The cold land breeze then moves to the ocean while the warm sea breeze moves to the land as a result of convection.
