Unit 6 (Southwest and South Asia): Why was India divided into two different
countries when it won independence from Britain?
Your answer
The reason why India was divided into two different countries after its independence from Britain, was to reduce religious conflict between Muslims and Hindus.
Why was India partitioned at independence ?The polarization of Hindus and Muslims had reached such a degree that many on both sides thought it was impossible for followers of the two faiths to coexist peacefully.
Muslims made up the largest religious minority in British India at about 25% of the total population. They had become accustomed to having their minority status preserved by a system of reserved parliamentary seats and distinct electorates while living under imperial rule. The British system of political control, also referred to as "divide and rule," depended on identifying interest groups prepared to work together.
As a result, the Muslims knew that it would be best if they had their own nation and so advocated for it. This led to India being divided into the nations of India and Pakistan when independence was won from the British.

The term "globalization" describes the growing interconnection of various regions of the world. The procedure entails a type of reciprocal interchange of beliefs, principles, and ideas.
The process benefits all of the interacting civilizations, either positively or negatively. On the whole, globalization is attributed to the improvement of the local culture. For instance, the culture of wearing blue denim is unique to Western civilizations, namely American society, and represents the widespread struggle for women's suffrage, the advancement of capitalistic values, and civil rights.
Blue denim was explicitly forbidden in the USSR during the cold war, a time when US-USSR tensions were at their highest. USSR wanted to forbid it in an effort to distance itself from western capitalism and civil rights movements.
The exchange of capitalistic and democratic ideals finally came about as a result of the greater east-west connection, and gradually blue denim came to rule the world as a symbol of freedom and liberty.

what may occur when convergent boundaries interact? formation of island chains creation of mid-ocean ridges creation of convection currents
The correct response is a) formation of island chains. The event formation of island chains is associated with convergent boundaries. An area where two plates converge is referred to as a convergent border. The borders of one or both colliding plates may bow up into mountain ranges as a result of the impact, or one plate may bend downward into a deep undersea trench.
A region on Earth where two or more lithospheric plates clash is known as a convergent boundary, also referred to as a destructive boundary. Subduction is the inevitable sliding of one plate beneath the other. The Wadati-Benioff zone, a plane with a high frequency of earthquakes, can be used to designate the subduction zone. These collisions take place over timescales of millions to tens of millions of years and can cause deformation, earthquakes, volcanism, orogenesis, lithosphere destruction, and orogenesis. Oceanic-oceanic lithosphere, oceanic-continental lithosphere, and continental-continental lithosphere all have convergent borders. Depending on the types of crust, convergent borders have different geologic characteristics. Convection cells in the mantle are what propel plate tectonics. Convection cells are produced when cool materials from the surface return to the mantle and heat produced by radioactive decay of mantle components escapes to the surface. These convection cells create new crust by bringing heated mantle material to the surface along spreading centres. The creation of younger crust pushes this new crust away from the spreading centre, where it cools, thins, and gets denser. When this dense crust converges with less dense crust, subduction starts. The subducting slab is propelled into the mantle in part by the force of gravity.

The triggering mechanisms that is likely implicated in the failure of most or all of the Stillaguamish landslides is increasing thickness of material on the top of the hillslope through sedimentation.
The sliding down of a slope of a mass of rock, rubble, or earth is known as a landslide. Landslides are a sort of "mass wasting," which refers to any downward movement of soil or rock caused by gravity alone. Five different slope movement types are referred to as "landslides": falls, topples, slides, spreads, and flows. By the type of geologic material, these are further separated (bedrock, debris, or earth). Common landslide types include debris flows, often known as mudflows or mudslides, and rock falls.
According to the findings, the worst landslide in American history occurred in two distinct phases. The first stage, which was primarily or fully composed of deposits from earlier landslides, remobilized the 2006 slide as well as a portion of the nearby forested slope from an ancient slide. In the end, the first stage caused almost all of the damage in the Steelhead Haven community and pushed more than six tenths of a mile over the north fork of the Stillaguamish River.

what is the seismic moment of an earthquake that slips 30 cm over an area of 15*30km^2 in rock with a shear modulus of 30 gpa?
The seismic moment of an earthquake is 405,000. Seismologists use a quantity called seismic moment to calculate the magnitude of an earthquake.
Thus, M 0 has torque dimensions that are expressed in newton meters. In the body-force equivalent description of seismic sources as a double-couple (a pair of force couples with opposite torques), the relationship between a seismic moment and a torque is obvious: the seismic moment is the torque of each of the two couples. Seismic moment is not a measure of energy despite having the same dimensions as energy. Indirect and approximate relationships exist between the seismic moment, potential energy decrease, and radiated energy. In order to constrain its variables, the seismic moment of an earthquake is often approximated using the information at hand. Seismograms, which are recordings of an earthquake's ground motion, are typically used to determine the moment for contemporary earthquakes.
The equation M0 = DAμ, where D is the average fault displacement, A is the total area of the fault surface, and is the average stiffness (with regard to shearing forces) of the rocks in the fault, can be used to calculate the seismic moment, M0.
