The Normalized Difference Vegetation Index is the most often used measurement (NDVI). Rock, sand, or snow-covered deserts correlate to very low NDVI values (0.1 and lower).
Although we sometimes take the plants and trees around us for granted, they are essential to practically every part of our lives. They offer us food and clothing, remove carbon dioxide from the air, give us oxygen, and give us supplies for homes and medicines. Our health, the economy, and the environment are all impacted when the vegetation around us undergoes significant changes. For instance, during a prolonged drought in the Sahel region of Africa twenty-five years ago, thousands of people perished from starvation. In the past fifty years, deforestation in South America has left thousands of acres fallow and wiped off several species, including those that would have produced useful medicines.

loess deposits in the u.s. midwest are derived from . group of answer choices the ohio river valley the rocky mountains top soil loosened by agriculture the sahara desert glacial outwash of the pleistocene age
Using the theories of loess, we got that from the Ohio river valley loess deposits in the U.S. mid west are derived.
Loess is classically viewed as the glacially derived sediment, leading to the view that loess deposits denote times of the increased glacial activity and the intercalated paleosols indicate the warmer interglacial or interstadial periods. However, the loess of the North America comes from both glaciogenic and the nonglaciogenic sources. The response of different loess regions of the North America to glacial and interglacial conditions varies, with the timing of loess deposition depending on interplay between various factors including the climatic conditions, sediment supply, sediment source, and vegetation cover.
Hence, loess deposits in the U.S. mid west are derived from the Ohio river valley.

seawalls are constructed perpendicular to the shore to prevent wave erosion. group of answer choices true false
True ,seawalls are constructed perpendicular to the shore to prevent wave erosion.
What is wave erosion ?
Waves may erode beaches on a variety of geographical and temporal dimensions. A scour zone moves up the beach or down the beach with every rise and fall in the tide. At the tide level, there is a turbulence zone where suspension of sediment is common. It is also the zone where the backwash meets the oncoming surge.
The erosion occurs between three percent and forty percent of the breaker height and deeper. As the tides vary, the breaker zone likewise moves down the beach. Sediment migration in the foreshore-inshore region is highest within the breaking zone. In actuality, the breaker zone is where nearly 50% of the sediment flow occurs.

when levels of certain aerosols increase or ash from large volcanic eruptions stays in the atmosphere for extended periods of time, some solar energy can be blocked from reaching earth's surface and can cause average global temperatures to decrease. this is a process called global cooling.
What is global cooling?
An imminent cooling of the Earth that would result in a period of severe glaciation due to the cooling effects of aerosols or orbital forcing was hypothesized, particularly during the 1970s. The scientific literature of the 1970s was largely more concerned with warming from an increasing greenhouse effect, but some journalistic reporting in that decade speculated about continued cooling.
The few temperature series that were available in the middle of the 1970s indicated that the temperature had been dropping for several decades prior to that point. It became evident that the average global temperature had significantly increased as longer time series of higher quality became available.
Scientists began to realise, by the 1970s, that estimates of world temperatures indicated cooling since 1945 as well as the potential for significant warming brought on by greenhouse gas emissions. Less than 10% of the scholarly articles that examined 21st-century climate trends tended to forecast future warming, while the majority expected future cooling. A 25% rise in atmospheric carbon dioxide over the 150 years from 1850 to 2000, together with a corresponding warming trend, was predicted by Science News in May 1959, despite the fact that the general public was mostly unaware of the effects of carbon dioxide on the climate. The actual growth during this time was 29%. Paul R. Ehrlich noted in 1968 that the cooling impact of aerosols was being countered by global warming from greenhouse gases.

The polar region is warming at a faster rate than most parts of the planet
because of Arctic amplification
What is Arctic amplification?
One distinction is how quickly terrestrial areas are warming compared to ocean places. But the Arctic is likely the biggest outlier, warming more than twice as quickly as the world average.
This process, called "Arctic amplification," is linked to extreme weather events in the northern hemisphere's mid-latitudes and is creating significant changes for Arctic communities.
The loss of snow and sea ice in the Arctic, which results in less incoming sunlight being reflected back out to space, is often cited as the reason of this rapid warming.
However, the truth is a little more nuanced than that. My co-authors and I examine the various aspects causing the Arctic's rapid change in a new paper that was just published in Frontiers in Earth Science.

Which diagram shows an oceanic-oceanic convergent boundary? describe what occurs at this type of plate boundary
Oceanic-oceanic convergence is shown in Diagram B. These plates generate a deep marine trench. In the ocean, parallel to the trench, volcanoes can potentially develop.
What are the convergent boundaries?
Different plates on our planet interact with one another, move past one another, and pull apart from one another. There are several diverse plate borders, breathtaking scenery, and perilous perils as a result of these motions between the plates. In general, there are three different types of plate contact. Convergent borders are the first of them, which we shall examine below.
Two or more tectonic plates can move toward one another at convergence borders. The two tectonic plates are squeezed or pushed together during the convergence process by compressional stress. Mountain chains are most frequently recognised to be formed by convergent boundaries. Earth has seen periods of supercontinent creation, during which the continents as we know them now were once combined into one landmass, as a result of tectonic plate collisions. Supercontinents used to exist more than 250 million years ago, and one well-known example is the ancient continent of Pangaea.

Metamorphic rocks will change when subjected to heat and pressure
What are Metamorphic rocks?
Although they began as a different kind of rock, metamorphic rocks have undergone significant alteration from their igneous, sedimentary, or previous metamorphic forms. Metamorphic rocks are created when rocks are exposed to extreme temperatures, high pressures, hot mineral-rich fluids, or, more frequently, some combination of these conditions. These kinds of situations can be found deep inside the Earth or where tectonic plates collide.
The process of metamorphism changes the rocks into denser, more compact rocks rather than melting them. Either by the rearranging of mineral constituents or through chemical reactions with fluids that enter the rocks, new minerals are produced. Even rocks that have already undergone metamorphosis might undergo changes due to pressure or temperature. Rocks subject to metamorphism are frequently crumpled, smeared, and compressed. Metamorphic rocks do not get hot enough to melt because if they did, they would turn into igneous rocks.
The metamorphic rocks phyllite, schist, gneiss, quartzite, and marble are frequently encountered.

A surface feature called a thermal low-pressure forms in the deserts of North America ( southeastern California )and southwest Arizona
What is thermal low pressure?
Thermal lows, also known as heat lows, are non-frontal low-pressure regions that develop over the subtropical continents in the summer season as a result of extreme warmth relative to their surrounding environments. [1] Thermal lows can be found close to the Sonoran Desert, on the Mexican plateau, in the Great Central Valley of California, over the Sahara, in north-western Argentina, in north-western Australia, over the Kimberley region of the Iberian Peninsula, and over the Tibetan plateau.
Through reradiated energy in the infrared spectrum, intense, rapid solar heating of the earth's surface heats the lowest layers of the atmosphere on land. A low-pressure area is created when hotter air rises because it is less dense than the cooler air around it. Because they warm up more quickly than the atmosphere around them at the same altitude, elevated places can strengthen the thermal low. When the air covering the land is colder than the warmer water body, instability lows develop over water during the winter.
