Answer:
sediment load
Explanation:
it refers to he combination of materials carried by a flowing water of stream, including rock, pebbles, clay and dissolved substances.
The total amount of material transported by a stream is commonly referred to as its sediment load.
This includes all of the solid materials, such as rocks, sand, and mud, that are carried by the water as it flows downstream. The sediment load can vary greatly depending on several factors including the velocity of the water, the size and shape of the particles being transported, and the volume of water flowing in the stream.
Streams with high velocities and larger volumes of water are typically capable of carrying larger and heavier sediment loads than slower-moving streams with lower volumes of water. Sediment load is an important factor to consider when studying rivers and streams, as it plays a significant role in shaping the landscape and influencing ecological processes within these aquatic environments.

a true desert is defined by a lack of what substance?
A true desert is defined by a lack of water. A desert is characterized by its arid and dry conditions, which are primarily caused by a scarcity of water.
Deserts typically receive very little precipitation, often less than 250 millimeters (10 inches) of rainfall per year. This lack of water is a defining feature of deserts and contributes to the harsh and inhospitable environment found in these regions. The absence of water in deserts has a significant impact on the ecosystem and the organisms that inhabit them. Plants and animals in desert environments have adapted to survive in conditions of limited water availability. They have developed various mechanisms to conserve water, such as deep root systems, water storage capabilities, and efficient water usage through specialized physiological adaptations.
The scarcity of water in deserts also affects human habitation and activities. It poses challenges for agriculture and settlement, as the aridity makes it difficult to cultivate crops or sustain large populations without access to alternative sources of water. However, despite the lack of water, deserts are not completely devoid of life. They support unique and resilient species that have adapted to thrive in these extreme conditions.

what is a moraine that piles up beside the glacier called?
A moraine that piles up beside a glacier is called a lateral moraine. Lateral moraines are formed by the accumulation of rocks, sediment, and debris that fall onto the glacier from the adjacent valley walls.
They are characterized by their location alongside the sides of the glacier. A lateral moraine forms when material from the valley walls or rockfalls onto the glacier's surface. As the glacier moves, it carries the debris along with it, and the material accumulates along the edges of the ice. This accumulation creates a ridge-like feature that runs parallel to the direction of glacier flow. Lateral moraines can vary in size and shape, depending on the amount of debris available and the movement of the glacier. Lateral moraines are an important feature in glacial landscapes as they provide evidence of the past movement and behavior of glaciers. They can also contribute to the formation of other types of moraines, such as medial moraines, which form when two glaciers merge and their adjacent lateral moraines combine. Overall, lateral moraines serve as a visible reminder of the powerful processes of glacial erosion and deposition.

The highlighted placemark in Problem 19 in Rocky Mountain National Park, CO highlights a cirque.
A cirque is a bowl-shaped hollow found at the head of a glacier, typically formed by erosion. It is often characterized by steep walls and a flat or gently sloping bottom. Cirques are commonly found in mountainous regions where glaciers have carved out the landscape over time. These features are formed through a combination of processes including freeze-thaw weathering, plucking, and abrasion by the moving glacier. As the glacier erodes the surrounding rock, a hollow basin is created, and the accumulated snow and ice in the basin feed the glacier. Over time, the cirque may become deeper and larger as the glacier continues to erode the surrounding terrain.

The northeastern United States has historically been the region most affected by acid rain in the country.
Acid rain occurs when emissions of sulfur dioxide and nitrogen oxides from power plants, factories, and vehicles combine with atmospheric moisture to form acidic compounds that can be carried great distances by prevailing winds. The emissions from power plants and other sources in the Midwest are carried by prevailing winds, causing acid rain to fall in the Northeast. This phenomenon has caused environmental damage to forests, lakes, and buildings in the region. However, with the implementation of regulations and cleaner technologies, the problem has significantly reduced over the years.
The 1990 Clean Air Act Amendments have played a significant role in reducing acid rain as it required major emission reductions of sulfur dioxide and nitrogen oxides from power plants. Today, acid rain is still a concern but has been greatly reduced compared to its peak in the 1970s and 80s.

In the Piedmont region of Georgia, oxidation is the most common type of chemical weathering, while karst topography is formed through the dissolution of limestone by acidic groundwater. Hydrolysis occurs when water reacts with minerals, producing different compounds.
Iron-rich minerals, such as iron sulfides or iron oxides, are commonly present in metamorphic rocks. When these minerals are exposed to oxygen and water, they undergo a chemical reaction known as oxidation. This reaction results in the formation of iron oxide minerals, commonly referred to as rust, which causes the rocks to weather and disintegrate.
When underground limestone is dissolved by acidic groundwater, it forms a landform known as karst topography. Karst topography is characterized by the dissolution of soluble rocks, such as limestone, by acidic water. As the acidic groundwater flows through the limestone, it chemically reacts with the calcium carbonate (CaCO3) present in the rock, leading to its dissolution. Over time, this dissolution process creates various landforms, including sinkholes, caves, underground drainage systems, and distinctive surface features such as limestone pavements or tower karsts.
The type of chemical weathering that occurs when water chemically reacts with minerals to produce different compounds is called hydrolysis. Hydrolysis involves the breaking down of minerals through the reaction with water molecules. In this process, water chemically interacts with the minerals, leading to the formation of new compounds. For example, in the presence of water, feldspar minerals commonly found in igneous and metamorphic rocks can undergo hydrolysis, resulting in the formation of clay minerals.

In general, older stars have lower c. abundance of heavy elements than younger stars.
Nearly all the hydrogen and helium in existence was formed in the first three minutes or so after the Big Bang, when the entire universe was extremely hot and dense. However, even those conditions weren’t right for keeping nuclear fusion going, so very few heavier elements were produced. Most of the rest of the elements, known to astronomers as “metals”, were created by nuclear fusion in stars.
Though we only have indirect evidence for them so far, the first stars in the universe were very massive and made entirely of hydrogen and helium. The supernova explosions of these early stars produced and spread the first metals. Younger generations of stars formed partly from these heavier elements, and continued the cycle. As a result, the number of metal atoms has increased with every generation of stars, although hydrogen and helium still make up about 99% of all atoms in the universe today.
