Discrete fragments of oceanic or continental crust accreted to the edge of a craton by an active margin are called terranes or accreted terranes.
Terranes are discrete fragments of crust that have been transported by tectonic processes and accreted to the edge of a craton, which is a stable part of the continental lithosphere. This typically occurs along an active margin, where two tectonic plates are converging, and one is being subducted beneath the other.
The subducting plate can carry with it pieces of oceanic or continental crust that become detached and transported to the overriding plate.
These terranes can have a different geological history and composition from the surrounding craton, and their accretion can play a significant role in the evolution of continental margins and the formation of mountain ranges.
Terranes are often recognized by their distinctive geologic features, such as fossils, rock types, and structures, that differ from those of the surrounding rocks.

Desertification occurs when drought and human activity destroy once-fertile land and water resources. The Sahel region of the Sahara is an area particularly affected by desertification. Lake Chad, located within the Sahel, is now referred to as “Africa’s disappearing lake,” as it is literally shrinking. Watch this video on desertification and read this article about Lake Chad. Based on what you learn from these resources, write a brief essay giving specific examples of how human activity has contributed to the problem of desertification in the Sahel region. How has the problem affected Lake Chad? How has it endangered the local population’s way of life?
Answer:
Human activity, including irrigation practices, hydroelectric dams, and intense agricultural use, have led to desertification in the Sahel region. In addition, global warming has added to the problem. Over time, the soil becomes overused and sterile. As that dry and arid soil moves, it begins to encroach on local bodies of water. Lake Chad, as a result, has shrunk in size. Just 40 years ago, this lake contained 15,000 square miles of water. It now contains just over 500 square miles of water.
The locals of this region depend heavily on both fertile soil and healthy bodies of water for survival. Desertification can greatly endanger their way of life. For example, famers cannot produce the necessary crops, and fishers cannot rely on as much seafood. The article mentions that fishers who used to be able to fill hundreds of traps can now barely fill one. Desertification in the Sahel and its impact on Lake Chad will have a lasting effect and could possibly mean a different way of life for generations to come in the region.
Explanation:
The Sahel region's desertification is an issue as, without the roots of trees and other plants, the wind may easily sweep the dust away.
Due to these problems, water is now in short supply for local residents, animals, and plants. Farmers and herders are unable to continue living their traditional lifestyles without access to water and productive land.
How has desertification affected Lake Chad?
The "Basin" of Lake Chad, which makes up over 8% of the continent, is divided among seven nations: Algeria, Cameroon, Libya, Chad, Niger, and Nigeria. Due to overuse and the consequences of climate change, the water body has decreased by 90% since the 1960s.
As a result of desertification and climate change, which have reduced Lake Chad's surface area by 90% since 1960, the lake is gradually disappearing. The lake is located in the center of the humanitarian catastrophe brought on by the fight with the Boko Haram group's armed forces, making it dangerous to access what little is left.
The lake was formerly among the world's greatest bodies of water.

It takes the water content of about ______ cloud droplets to form a single raindrop.
It takes the water content of about 1,000,000 cloud droplets to form a single raindrop.
What is cloud droplets?The tiny particles called cloud droplets are what give rise to all the well-known, observable, non-precipitating clouds that are discussed in Chapter 1 (stratus, stratocumulus, cumulus, altostratus, altocumulus, and cirriform clouds).
What causes cloud droplets?When airborne water vapor in the form of visible water droplets or ice crystals condenses, clouds are created. In order for this to occur, the air parcel must be saturated, meaning that it must be unable to keep all the water it contains in vapor form, causing it to begin condensing into a liquid or solid form.

Which of these poses the greatest challenge to the sovereignty of a nation-state in the developing world?
The increasing mobility of labor
The existence of multiple political parties
The movement toward supranationalism
The activities of multinational corporations
The spread of democracy
Answer:
The activities of multinational corporations.
Explanation:
Multinational companies are those economic corporations that offer goods or services in more than one country, thus grabbing large market shares at the international level.
These companies generally have large sums of capital to invest, with which they tend to exert an enormous influence on nations with fewer economic resources. Thus, when investing in underdeveloped countries, these countries give up more than a market share, but also on many occasions their own power to exercise their sovereignty, mainly in relation to their natural resources and the administration of their territory.

how might a plateau show the effects of both tectonic process and erosion?
Answer:
Erosion makes the plateau look flat, due to weathering.
Tectonic processes may cause the plateau to be elevated, which means it might be higher if there is more tectonic processes
Hope this helps!
Dissected plateaus and volcanic plateaus are the two different types of plateaus.As the Earth's crust moves upward, a dissected plateau develops.The gradual clash of tectonic plates is what causes the uplift.
How do plate tectonics affect erosion?
Additionally, tectonic activity creates topography with high relief that is vulnerable to erosion, leading to increased erosion rates.There has been a lot of discussion on how slope and relief can affect erosion rates (e.g., Ahnert 1970; Portenga and Bierman 2011; Summerfield and Hulton 1994). Furthermore, it is evident that tectonics can have a direct impact on erosion rates on a short time scale in the case of earthquakes, which can result in landslides and weaken the rock in the area through seismic disturbances. The loss of crust from an overriding tectonic plate as a result of subduction is known as tectonic erosion or subduction erosion.There are two forms of tectonic erosion: basal erosion occurs at a plate's base and frontal erosion occurs at a plate's outer boundary.The overriding plate becomes thinner as a result of basal erosion. Plateaus feature abundant mineral resources, which makes them very useful.The plateau regions of the world are home to many mining locations.The African plateau, for instance, is well known for its gold and diamond mining.There are enormous amounts of iron, coal, and manganese on the Chhotanagpur plateau in India. As magma from deep within the Earth pushes toward the surface but is unable to penetrate the crust, many plateaus are created.Instead, the massive, flat, impermeable rock above it is raised by the magma.According to geologists, the Colorado Plateau may have received its final lift beginning around ten million years ago from a cushion of magma.To learn more about plateau show refer

Name and discuss the various pressure belts of the world
The ITCZ creates a significant climate shift, and it has a significant impact on the development of tropical storms and hurricanes.
The various pressure belts of the world are described below:
Polar high-pressure belts: Polar high-pressure belts are found at high latitudes near the north and south poles. The Polar regions experience less incoming solar radiation due to the low solar angle, resulting in lower temperatures. Polar high-pressure belts are a result of these conditions. Because the air over the poles is very cold, it sinks.
Subtropical high-pressure belts: Subtropical high-pressure belts are found at about 30 degrees north and south latitudes. Subtropical high-pressure belts are formed as a result of the warm and moist air rising from the equator, moving towards the poles, and eventually cooling and sinking as it moves away from the equator. These high-pressure belts have a huge impact on the world's weather patterns because they control the position of the world's deserts and drylands.
Equatorial low-pressure belts: The equatorial low-pressure belt is a broad belt that is located at the equator and includes a region of very low atmospheric pressure. The intense solar radiation heats the air and causes it to expand, resulting in a decrease in air pressure at the surface. The expanding air rises, cools, and then spreads north and south of the equator, producing areas of abundant precipitation.
Inter-tropical convergence zone: The Intertropical Convergence Zone (ITCZ) is a belt of low pressure and heavy rainfall that circles the Earth's tropical region. It is formed when the northeast trade winds from the northern hemisphere and the southeast trade winds from the southern hemisphere converge near the equator. Because of the ITCZ's movement, the rainy season shifts across the equator twice a year.

geologic principle of uniformitarianism and how it allows us observations of what we see today in earth processes to interpret the geologic record.
The geologic principle of uniformitarianism states that the same natural laws and processes that operate today have been at work throughout Earth's history.
It suggests that the processes and phenomena observed today can be used to interpret the geologic record and understand the past. Uniformitarianism allows us to make inferences about past Earth processes by studying present-day processes. By examining geological features, such as rock formations, sedimentary layers, or erosional patterns, and comparing them to modern-day analogs, we can draw conclusions about the processes that formed them in the past. For example, studying the erosion patterns of a river today can provide insights into the formation of ancient river valleys.
This principle also helps us understand long-term changes and trends in Earth's history. By studying the slow accumulation of sedimentary layers, the formation of volcanic deposits, or the gradual changes in landscapes, we can extrapolate these processes over vast periods to interpret the geologic record.
However, it is important to note that uniformitarianism does not imply that all geological processes have occurred at the same rate throughout history. Earth has experienced both gradual changes and catastrophic events, and these variations need to be considered when interpreting the geologic record.
