Why is central america prone to earthquakes? question 11 options: the region lies on the border of two tectonic plates. the soil is soft and easily moves. the building codes are old and outdated. there is no clear reason why the area is prone to earthquakes.
The correct answer is option A: the region lies on the border of two tectonic plates.
Central America is prone to earthquakes because the region lies on the border of two tectonic plates.
A large number of earthquakes occur in Central America because it is located in a region that is seismically quite active in the world.
Most active regions are along the North American - Caribbean plate boundaries and Cocos - Caribbean plate boundaries.
Earthquakes are abundant in these areas due to the excessive relative movement between the tectonic plates. However, active volcanoes are also responsible for the convergent movement of the plates along the boundaries.
To put it simply, Central America holds a lengthy history of destructive and damaging earthquakes.

The hypotenuse of a right triangle measures 18 cm and one of its legs measures 7closed
Answer:
The other leg is 16.6 cm (approximately)
Explanation:
We have a right triangle, with the hypotenuse = 18, one side = 7, and the other side = x.
Since this is a right triangle, we will use the Pythagorean Theorem to find the value for x.
So, let a = 7 for one side, and let c = 18 for the hypotenuse. And, let c = x for the other side.
The Pythagorean Theorem is:
c^2 = a^2 + b^2.
So, 18^2 = 7^2 + x^2
324 = 49 +x^2
And, x^2 = 324 - 49 = 275
So, x = sqrt(275) = 16.58 cm (approximately).
Conclusion: The other leg is 16.6 cm (approximately).

Find the measure of two supplementary angles
The measure of two supplementary angles = 180°.
Then m∠A = 104° and m∠B = 76°
According to the supplementary angles m∠A + m∠B = 180°
In the given question m∠A = (3x - 7)°,
m∠B = (2x + 2)°
then (3x - 7) + (2x + 2) = 180°
3x - 7 + 2x + 2 = 180°
5x - 5 = 180°
5(x - 1) = 180°
(x - 1) = 180 ÷ 5
x - 1 = 36
x = 37°
If x = 37°, then m∠A = 3(37°) - 7
= 111 - 7
= 104°
Similarly, m∠B = 2(37°) + 2
= 74 + 2

List at least three points of evidence for plate tectonics below and explain how each supports the theory of plate tectonics.
The existence of fossils, glaciers, and complimentary coasts all provide evidence for how the plates originally interacted.
Plate tectonic activity frequently leads to magma formation, igneous intrusions, metamorphism, volcanic activity, earthquakes, faulting, and folding. Deep fault systems split the crust of the world into six large and roughly twenty smaller parts.
The discovery of very identical fossils in rock blocks separated by great distances and oceanic stretches was one of the earliest lines of evidence pointing to the existence of plate tectonics. It implied that those land parcels had once been linked.
The locations of earthquakes and volcanoes, frozen at solidification, coral islands, ocean trenches, magnetic striping, the age of the rocks that make up the ocean's crust, and the progressive expansion of rifts are all evidence that certain places have moved, as well as evidence that neighboring locations were not always next to each other and/or had different orientations.

Three points of evidence for plate tectonics are:-
1. The shapes of many continents are such that they look like they are separated pieces of a jigsaw puzzle. For eg., if you look at the map of the world and see the shape of the east coast of North and South America then it seems they are relative to the shape of the west coast of Africa and Europe.
2. Many fossil comparisons along the edges of continents that look like they fit together suggest species similarities that would only make sense if the two continents were joined at some point in time in the past and hence confers the movement of the plates.
3. There are ridges, such as the Mid-Atlantic Ridge where plates are separating that are produced by lava welling up from between the plates as they pull apart. Also, there are mountain ranges being formed where plates are pushing against each other eg., the Himalayas, which are still growing.
There are seven major tectonic plates.
Movement in tectonic plates can cause tsunamis, earthquakes, and volcanic eruptions. These are some of the major proofs of plate tectonics.

As atmospheric temperature rises, more arctic sea ice melts. The sea-ice reduction in turn decreases the surface albedo and causes the temperature to rise even more. This scenerio is an example of?.
Snow and ice cover less of the Earth's surface as a result of melting due to an increase in global temperature, which also lowers albedo. More energy is absorbed due to the decrease in albedo, which leads to increased warmth and melting.
Global temperature is significantly influenced by the equilibrium between the amount of solar energy reflected and absorbed by the Earth's surface. Snow, ice, and water on Earth have different capacities to reflect and absorb solar energy, and melting polar ice triggers a positive feedback loop that hastens global warming.
Pollution, including soot, decreases the albedo of ice and speeds up melting.

The study of how people and the environment interact is known as cultural geography. Though there are many avid football supporters in Montana, for instance, the state's culture is less football-centric than that of the South. This is due, in part, to the milder winters in the South, which make it easier for people to play football.

How does a change in the solar constant impact the absorption of shortwave radiation and the emission of longwave radiation by the earth-atmosphere system?.
The Earth-Atmosphere system will emit more longwave radiation as a result of a higher solar constant because it will absorb less solar radiation.
Any object with a temperature emits electromagnetic radiation (light). Longwave radiation has a lower energy content while shortwave radiation has a higher energy content. Because the sun is very hot and has a lot of energy to give off, it emits shortwave radiation. However, because Earth is far cooler than the sun but still emits radiation, it does so in the form of longwave radiation. Hence, a change in solar constant causes the earth to emit long wave radiation instead of shortwave radiation.

Acientists detected channels or gullies on the surface of mars, and deduced that there may have been water there. This kind of claim uses what kind of inference?.
A scientist detecting d channels or gullies on the surface of mars, and deduced that there may have been water there shows inductive inference.
What is inductive inference?Inductive inference is based on a generalization from a limited set of previous observations, extending the observed pattern or relationship to other future instances or instances occurring elsewhere. Inductive inference begins with propositions about data and ends with propositions about things other than data.
Many scientists believe that liquid water once flowed through the gullies and channels visible on Mars' surface. By comparing them to similar features on Earth, it is assumed that these were formed in part by water erosion. Some of these channels are quite large, reaching lengths of 2,000 kilometers and widths of 100 kilometres.

The degree of migration's selectivity varies greatly between ethnic/origin country groupings and the nations to which these groups have migrated. Positively selected immigrant communities might be less disadvantaged than neutrally or negatively selected immigrant communities, but institutions in the destination country are likely to change the size of these disparities.
In comparison to homestayers, migrants are said to be more positively self-selected in terms of educational attainment, motivation, ability, and effort.
