Answer:
Continental lithosphere is thicker than oceanic lithosphere
Answer:
Continental lithosphere is thicker than oceanic lithosphere
Explanation:
The continental crust is formed essentially of aluminous silicates (that is why it was formerly called sial) and has an overall composition similar to that of granite. It measures 25 to 50 km thick and the primary seismic waves propagate at 5.5 km / s.
The oceanic crust is composed essentially of basalt, formed by magnesian silicates (hence the formerly called sima). It is 5 to 10 km thick and is denser than the continental crust because it contains more iron. Seismic waves have a speed of 7 km / s.
If the measure of a tangent chord angle is 68 degrees then what is the measure of the intercepted arc inside the angle
Answer:
136°
Explanation:
Theorem: The measure of the angle formed by a tangent and a chord is equal to one-half the measure of the intercepted arc.
In the diagram below, PR is the chord, PRS is the tangent, and PQR is the intercepted arc.
Per the theorem,
mPRS = ½mPQR
mPQR = 2mPRS = 2 × 68° = 136°
The measure of the intersected arc is 136°.
Theorem: The measure of the angle formed by a tangent and a chord is equal to half the measure of the intercepted arc.
The diagram below shows the chord PR, the tangent PRS, and the intercepted arc PQR.
This is theorized,
12mPQR = mPRS
mPQR=2mPRS=2 68°=136°
The intersecting arc has a 136° length.
What are the 5 theorems?Thales of Miletus, who lived and worked around 600 BC, is credited with some of the earliest geometric arguments that are still in use today.
In specifically, he is credited with proving the following five theorems: Any angle scribed in a circle is divided by any diameter, any angle scribed in a semicircle is a straight angle (90°), and opposite Two triangles must be congruent (of the same shape and size), the "vertical"angles created by the intersection of two lines must be equal, and isosceles triangles must have equal base angles.
The English mathematician Thomas Heath (1861–1940) presented what is now known as Thales' rectangle (see the picture) as a demonstration of (5) that would have been consistent with what was known in Thales' era, despite the fact that none of Thales' original proofs have survived.

An archaeological team has been excavating three ancient village sites—Barras, Agna, and Cussaia—looking in particular at kitchen waste dumps as a way to understand the villages’ dietary patterns and trading relationships. What follows are brief summaries of their findings.
Answer:
By excavating the kitchen area the archaeological team understands the ways of the ancient villages' consumption of food and the trading of the consumable items along with the potteries which can be found in the waste dump areas. By excavating these villages the pattern of growing crops can be understood if they cultivated or consumed wild crops, along with whether the society was agrarian or hunter-gathering. The dietary patterns of eating, drinking, and utensils with food residues can be examined.

Tijuana and Mexicali: (A) are planning to participate in the maquiladora program.(B) are located just opposite the U.S. city of El Paso.(C) were among the first border cites to experience a growth surge. (D) are key cities in the south of Mexico.
Answer:
C) were among the first border cites to experience a growth surge.
Explanation:
During the 1960's, maquiladora industries quickly grew geographically and economically and by 1985, had become Mexico's second largest source of income from exports, after income accounted to oil. After 1972, maquiladoras have also been half of Mexico's exports.
Tijuana became a dominant city in the border between California and Mexico, with a notable economic and industrial grow across the north of Mexico. Bordering San Diego, CA, Tijuana has around 600 industrial complexs that range from electronics, consumer , aerospace and medical industries. Tijuana holds the largest medical device manufacturing in all of the continent. Aerospace devices are also a motor for the region.
The rapid growth lead to heavy waves of working migrants moving there.
Similarly, Mexicali has greatly grew into a manufacturing hub, along tourism trade and the constructing sector. The Mexicalli Valley is becoming
a center that attracts more investment and makes relying more to the neighbouring Mexico.
How did your prediction compared to the actual changes in sea level? What have you learned about sea level variations?
1. My predictions about the changes in sea level have been relatively close to the actual rise of the sea waters, though it has been different than the general predictions of the numerous models of the countries. The predictions that I have made about the rise of the sea level have been based on the rate of melting of the polar ice, but also on the isostatic rebound that occurs because of it, and the influence that the greenhouse gasses have on the global temperature. The estimates that I made were showing a rise of only few centimeters, unlike the several meters predicted by most of the models. The closest model to what I have predicted is the Russian model, which is very different than the others.
2. The sea level variations are not very easy to predict, nor do they have any particular cycle that is repeating on approximately the same time. There are numerous factors that influence the variations of the sea level, such as the global temperature, with higher temperature meaning higher sea levels, and lower temperature meaning lower sea levels. The isostatic rebound of the continental land masses should also be taken in consideration, as the continents lift up when they don't have pressure on top of them from the ice, and sink down when they do have large ice masses on them, thus it can influence where the water can penetrate and where it can't. The position of the landmasses, composition of the atmosphere, as well as the geological activities, all have big influence on the variations of the sea levels, be it going up or down.

Fossil fuels are natural resources that are nonrenewable.
A. True
B. False
Final answer:
Fossil fuels including coal, oil, and natural gas are indeed nonrenewable resources because they take millions of years to form and cannot regenerate as quickly as they are consumed.
Explanation:
The statement 'Fossil fuels are natural resources that are nonrenewable' is A. True. Fossil fuels, which include coal, oil, and natural gas, are formed from the remains of ancient organisms such as plants and microorganisms. These resources take millions of years to form through natural processes involving decomposition under heat and pressure.
Because they are consumed much faster than they can naturally regenerate, they are considered nonrenewable. Today, fossil fuels are the dominant energy source for humanity but given their nonrenewable nature, there is a vital need to transition to alternative energy sources, such as renewable energies, that can be replenished.

Which of the following is not associated with the concept of “enclave urbanism”? New Middle Class Geographical Fragmentation Interconnected Neighborhoods Gated Communities
The reason why interconnected neighborhoods would be the correct answer because interconnected neighborhoods is not associated with the concept of enclave urbanism.
Enclave urbanism is a place where the people that live in it are in a class that's different than the classes that are surrounding it. For example, a distinct place could be a neighborhood filled with upper class people, while the neighborhoods surrounding it could be middle and lower class. It's more so like a "separation" between classes.
However, in a interconnected neighborhood, the neighborhoods would be connected together. These neighborhoods would have a good mix of classes, since they're all connected together.

(A) Coral reef
(B) Cold seeps
(C) Hydrothermal vents
(D) Kelp forests
(E) Rocky intertidal zone
Answer: (A), (B), (C) and (E)
Explanation:
Coral reefs are found in the oceans formed by the accumulation of the skeletal remains of the invertebrates. They are found under water.Cold seeps refers to those area where the gases such as methane, hydrogen sulfide comes out through the vent, under water.Hydrothermal vents are the places where the hot intruding magma reacts with the sea water producing a vent.Rocky intertidal zone refers to the zone between a high and a low tidal mark.Thus under the ocean, the structures such as coral reefs, cold seeps and hydrothermal vents forms where the tide is not so high and not so low.
Kelp forest is the odd one, that refers to those brown colored seaweeds, having high nutrients in salt water.
Early in the 20th century a geophysicist/astronomer named Milutin Milankovitch studied orbital forcing cycles including axial precession, precession of equinoxes, and orbital eccentricity. Which of the orbital forcing cycles is related to the wobble in tilt of Earth's axis
Answer: Axial Tilt (obliquity) cycle
Explanation:
Milankovitch's theory explains that Earth's orbit is influenced by three basic parameters that modify the planet's translation and rotation movements:
1. Variation of the Eccentricity of the orbit cycle, which influences the amount of solar radiation the Earth receives.
2. Variation of the axial Precession cycle, due to the flattening of the terrestrial sphere, causing the modification of the relative position of the solstices and the equinoxes with respect to aphelion and perihelion.
3. Variation of axial tilt (obliquity) cycle, which is related to the changes in the angle of inclination of the Earth's rotation axis in its orbit around the Sun. This phenomenon is responsible for the seasons and although the amount of radiation the Earth receives does not change, its distribution on the surface does vary.

Factors involved Agricultural practices, where the members of a farming family produce only enough food for themselves and do not make use of large-scale irrigation, chemical fertilizer, or machinery and technology, is called in soil formation. Below are factors involved in soil formation, except
(A) weathering of parent materials
(B) freezing/thawing
(C) growth of tree roots
(D) amont of fertilizer
Answer:
(D) amont of fertilizer
Explanation:
For a soil to form, the process of weathering must have taken place. Weathering is the physical disintegration and chemical decomposition of rocks to form soils and sediments. When organic matter, air and water incorporates with products of weathering, soils form.
Weathering of parent materials, freezing and thawing, growth of tree roots all leads to the physical disintegration of rocks. This is known as physical weathering.
Fertilizers add nutrients to the soil through artifical means and do not contribute to soil formation.
Why are the magnetic lineations identical on either side of the mid-ocean ridge?
Answer:
because volcanoes in the center of the ridge push the pre-existing seafloor on either side of it away from it at equal speeds
also when the earth's polarity flips, the crystals on either side of the spreading center are affected equally, so the bands are always the same distance from the ocean ridge
also because when the magma solidifies (which is what "freezes in" the magnetic orientation), the magnetic field of the earth exerts the same force on both sides of the ridge (the midline of the spreading).
Explanation:
Final answer:
The identical magnetic lineations on either side of mid-ocean ridges are due to the recording of the earth's magnetic field in cooling magma during seafloor spreading, as explained by the Vine-Matthews-Morley hypothesis. These symmetrical patterns of alternating magnetic polarity serve as records of past magnetic reversals and ocean-floor movement.
Explanation:
The magnetic lineations on either side of the mid-ocean ridge are identical because of the process of seafloor spreading and magnetic reversals. As new magma comes out of the mid-ocean ridges and cools, it records the earth's magnetic field at that time. This process, known as the Vine-Matthews-Morley hypothesis, shows that as the seafloor spreads, the magma solidifies and locks in the current magnetic polarity. If the earth's magnetic field is normal, the frozen magma will exhibit a positive magnetic anomaly, which corresponds to the current magnetic direction. If the field is reversed, the new crust will have a negative magnetic anomaly. As the earth's magnetic field has switched back and forth over time, this process has left a symmetric pattern of magnetic stripes--alternating between normal and reversed polarity--on both sides of the ridge.
The width of these magnetic stripes can also provide information about the rate of ridge spreading, with wider stripes indicating a period of faster spreading. Thus, these symmetrical magnetic lineations serve as a historical record of ocean-floor movement and help scientists reconstruct past tectonic activity and spreading rates.
Mexicans of mixed Spanish and indigenous heritage are
Mayan.
mestizos.
maquiladoras.
conquistadors.
Answer:
mestizos
Explanation:
The Mexicans are mostly of mixed ancestry, Spanish and from the native populations. Over yhe course of several hundred years, the Spaniards have mixed with the indigenous populations, thus giving rise to a unique group of people, the mestizos. The mestizos can simply be defined as people that have mixed origin of Caucasoid and Mongoloid parents. The Spanish are of the Caucasoid race, while the indigenous people of Mexico are considered as part of the Mongoloid race, thus when people of these two groups mix, we have mestizos.
Which italian city is home to the last supper
Answer:
Milan
Explanation:
The Last Supper measures 460 cm × 880 cm (180 in × 350 in) and covers an end wall of the dining hall at the monastery of Santa Maria delle Grazie in Milan, Italy. The theme was a traditional one for refectories, although the room was not a refectory at the time that Leonardo painted it.
"The correct answer is Milan.
Milan is the Italian city that is home to the famous mural painting ""The Last Supper"" by Leonardo da Vinci. This masterpiece is located in the refectory of the Convent of Santa Maria delle Grazie, a UNESCO World Heritage site. Painted between 1495 and 1498, ""The Last Supper"" depicts the scene of the last meal shared by Jesus Christ with his disciples before his crucifixion, as described in the Christian Bible. The painting is renowned for its innovative use of perspective and its emotional depth, capturing the moment when Jesus has just announced that one of the disciples will betray him. Despite the painting's deterioration over the centuries due to environmental factors and damage from war, it has undergone several restorations to preserve it for future generations.
Lava flows shaped the basins that formed the Great Lakes.
A. True
B. False
Answer:
B. False
Explanation:
The basins of the Great Lakes have not been shaped by lava flows, but instead they have been shaped by glaciers. The Great Lakes are relatively new lakes. Until relatively recently, more specifically, until the end of the last ice age, that area was covered in a very thick layer of ice, or rather glaciers. As the glaciers were pressing the crust with their weight, as well as causing erosion with their movement, they managed to create the basins of the Great Lakes. Once the climate warmed, and the glaciers started to melt, the basins got filled with water from them, thus creating the Great Lakes that we see in the present.

B. The deepest earthquakes occur along convergent plate boundaries.
C. When rocks move in any direction along a fault, an earthquake occurs.
D. Earthquakes cannot occur along transform plate boundaries.
Answer:
D. Earthquakes cannot occur along transform plate boundaries.
Answer:
D. Earthquakes cannot occur along transform plate boundaries.
Explanation:
Earthquakes occur both along plate edges and along faults lines in the Earth’s crust.. Most earthquakes occur along the edge of the oceanic and continental plates. Earthquakes can also occur far from the edges of plates, along faults. Normal faults are the cracks where one block of rock is sliding downward and away from another block of rock.
Faults are basically cracks in the continental or oceanic plates triggered due to plate tectonics. The crust is highly unstable in the vicinity of fault lines and disturbances along the fault lines might trigger massive earthquakes.
