how has the desert landscape of the sahara influenced historical migration patterns in africa?

Answer:

The Treaty of Guadalupe Hidalgo

Explanation:

The Gadsden purchase or Treaty completed the continental united states and ended manifest destiny.

America purchased more land from Mexico as part of its "Manifest Destiny" policy, which included building a railroad along the southern route from California to Texas. The United States was now connected to both the Atlantic and Pacific oceans.

The Gladsden purchase was the final component complete the continental US and ended manifest destiny. According to the "Manifest Destiny" theory, America's right to colonize and develop into the region between the Atlantic and Pacific Oceans was given to it by God. The American federal government was shaped by this policy for a significant portion of the 19th century.

One example of a territorial acquisition that perfectly embodies Manifest Destiny is the purchase of Louisiana. By the time the US took over this region from France, it had almost doubled in size. Thomas Jefferson's acquisition of this region in 1803 marked the start of the Manifest Destiny era. Another example is the Mexican Cession. winning the Mexican-American for the US.

Primordial heat is the internal heat energy accumulated by dissipation in a planet during its first few million years of evolution.

Primordial warmness is the internal warmness strength gathered via dissipation in a planet in the course of its first few million years of evolution. the primary contributions to the primordial heat are accretional electricity – the strength deposited by infalling planetesimals – and differentiation strength. Primordial warmth is all the warmness left over from when the Earth formed. four and a 1/2 billion years ago our planet was fashioned by the collision of rocks and dirt. over the years it grew from the dimensions of a small rock into our huge planet simply from rocks colliding with every other time and again and another time.

Land Use/Land Cover Change Sometimes, land is used without consideration for the environment. As a result, the land becomes unusable and the environment may be harmed.

Land cover change denotes a change in certain continuous characteristics of the land such as vegetation type, soil properties, and so on, whereas land-use change consists of an alteration in the way certain area of land is being used or managed by humans

This article suggests a method for evaluating climate and hydrological differences caused by localized changes in land use and land cover (LULCC) in developing nations.

In order to do this, temperature and precipitation fluctuations are correlated with the LULCC, and the impacts on evapotranspiration, infiltration, and runoff—all components of the local water balance—are estimated.

The conclusion that can be made from this statement is that electromagnetic waves do not require any medium to travel.

Electromagnetic waves are waves composed of an electric field and a magnetic field. In these waves, the electric field and the magnetic field oscillate perpendicular to each other and the direction of the net flow of energy is determined by a pointing vector which says that the direction of the net flow of energy is in direction of the cross product of the magnetic field vector and electric field vector.

Electromagnetic waves are a special type of waves that do not require any medium to travel and can travel in space as space is majorly vacuum.

For Part C: The difference between serpentinite and chlorite schist is that chlorite schist effervesces with the application of dilute HCl, whereas serpentinite does not.

For Part D: The difference between slate and phyllite is that the layers of slate are more flat than the layers of phyllite, which are noticeably wavy.

For Part C: The key difference between serpentinite and chlorite schist is that chlorite schist effervesces when exposed to dilute hydrochloric acid (HCl), while serpentinite does not. This characteristic reaction to HCl helps distinguish between the two rock types. Effervescence in chlorite schist indicates the presence of carbonate minerals that react with acid, whereas serpentinite lacks such carbonates, leading to no observable reaction with HCl.

For Part D: The primary difference between slate and phyllite lies in the texture and appearance of their layers. Slate exhibits flatter and smoother layers, while the layers of phyllite are noticeably wavy. This distinction in layer texture is often used to differentiate between the two rock types. The wavy layers of phyllite result from the presence of fine-grained minerals aligned in a preferred orientation, giving it a characteristic rippled appearance.

Continental go with the flow is the hypothesis that the Earth's continents have moved over geologic time relative to each other, as a result acting to have "drifted" across the sea bed. The idea of continental go with the flow has been subsumed into the science of plate tectonics, which researches the movement of the continents as they experience on plates of the Earth's lithosphere.

The speculation that continents might have 'drifted' was first put forward by way of Abraham Ortelius in 1596.

Six molecules of G3P are created per three Calvin Cycles, however, only one is utilized to make glucose. To restart the Calvin Cycle, the remaining five molecules of G3P are needed to regenerate RuBP.

One G3P molecule leaves the cycle and moves toward the production of glucose. 3 RuBP acceptor molecules are produced by recycling 5 G3P molecules.

However, each round generates two G3Ps, thus three turns result in six G3Ps. One G3P molecule is exported, while the other five stay in the cycle and are utilized to replenish RuBP, allowing the system to be ready for additional CO2 to be repaired.

A G3P molecule with three carbons exits the cycle after three cycles and joins a carbohydrate molecule. The leftover G3P molecules continue to cycle in order to be renewed into RuBP, which is then prepared to interact with more CO2.

Beach size varies with each storm, but on average over a few decades, a normal sandy beach's size is typically regulated by the equilibrium between sand supply from rivers or coastal erosion and sand loss to the deep sea. The right response in this case is option D.

The majority of beach materials are the result of erosive weathering. Water and wind erode the ground over a long period of time. For instance, certain rocks may break free as a result of the constant motion of waves crashing against a rocky bluff. Massive boulders can be reduced to the size of sand grains.

A rocky beach is produced when large waves carry sand offshore and onto longshore sand bars. A broad, sandy beach is produced when little waves push sand up the beach face.

Sand is created as rocks erode and weather over decades, even millions, of years. The decomposition of rocks, particularly quartz (silica) and feldspar require time. Rocks slowly move down rivers and streams, often beginning thousands of kilometers from the ocean, continually disintegrating along the way.

Complete question:

Beaches change size with every storm, but if you average over a few decades, the size of a typical sandy beach is usually controlled by: a group of answer choices

A dangerous hot ash and gases cloud that rolls down the side of a volcano during an explosive eruption is known as a pyroclastic flow.

Pyroclastic flows are composed of a hot mix of ash, volcanic rock fragments, and toxic gases, and they move very quickly down the side of a volcano at speeds of up to 100 mph. These flows can be incredibly destructive and can cause large-scale destruction over a wide area, including the complete obliteration of entire towns and villages.

The pyroclastic flow that occurred during the 1902 eruption of Mount Pelee in Martinique is a prime example of the destructive power of these flows. The eruption itself was preceded by a powerful earthquake, which caused the volcano to explode, sending a massive plume of ash and smoke high into the air. As the eruption continued, a pyroclastic flow cascaded down the side of the volcano at speeds of up to 100 mph. This pyroclastic flow incinerated the nearby town of St. Pierre in about three minutes, killing some 30,000 people in the process.

In addition to the sheer speed at which they travel, pyroclastic flows are incredibly hot, reaching temperatures of up to 1,830 degrees Fahrenheit. This heat is more than enough to cause severe burns, destroy buildings, and char trees and vegetation. Pyroclastic flows can also cause landslides and mudflows, which can further contribute to the destruction.
