The sediment load that travels in solution is?
a. dissolved load.
b. flow load.
c. suspended load.
d. bed load.
e. saltation.
The sediment load that travels in solution is dissolved load.
For particles to be a dissolved load in a stream, they must be smaller and less dense. Pebbles are about -6 mm in size and pebbles are 6-256 mm Sand grains are usually 0.125-2 mm in size, but their average density is high
With minerals, this is different because some minerals are larger and some seem. be smaller. Minerals have the property of dissolving during chemical reactions. Unlike dissolved load, the size of the particle transported as suspended load is determined by the velocity of the flow. As the flow moves faster, it can carry larger and larger particles. The larger the particle size the stream can carry, the higher the qualification of the stream.

a. The model predicts icy planets nearest to the Sun and we observe icy planets there.
b. The model predicts icy planets throughout the Solar System and we observe icy planets only far from the Sun.
c. The model predicts icy planets throughout the Solar System and we observe icy planets everywhere.
d. The model predicts icy planets throughout the Solar System and we observe icy planets only nearest to the Sun.
e. The model predicts icy planets farthest from the Sun and we observe icy planets there.
Answer:
a. The model predicts icy planets nearest to the Sun and we observe icy planets there.
Explanation:
The nebular model is a theory that explains the formation of the Solar System from a cloud of gas and dust known as the solar nebula. According to this model, the solar nebula collapsed under its own gravity to form the Sun and the planets. As the solar nebula cooled, solid particles called planetesimals formed. These planetesimals collided and merged to form the planets. The model predicts that the inner planets, including Mercury, Venus, Earth, and Mars, formed from material that was rich in rocks and metals, while the outer planets, including Jupiter, Saturn, Uranus, and Neptune, formed from material that was rich in ices such as water, methane, and ammonia. The model also predicts that the Kuiper Belt, a region of small, icy objects beyond Neptune, contains leftover planetesimals that did not form into planets. Observations of the Solar System support this model, including the presence of icy planets in the outer Solar System.
List 3 examples of a continually shifting population and densely population urban areas that have shaped US population patterns.
The Great Lakes, the Pacific coast, the Northeast, and the New England region are the most densely populated regions in the country.
Briefly explain population patterns in the USThe distribution of the population in the USA is not uniform. The shift of individuals from rural to urban areas has occurred over time in the United States. Population changes over time are influenced by natural change, internal migration, and external migration. Cities grew as a result of people migrating to cities in pursuit of employment and automated agriculture requiring fewer employees.
Today, the majority of Americans reside in urban regions. When compared to rural settings, where residents are dispersed across a much more sparsely populated terrain, cities tend to have more concentrated populations. Coastal places that draw individuals seeking a pleasant climate and economic possibilities, as well as locations with historic concentrations of American commerce and industry, lead to a population cluster there. A considerable portion of the population of the United States is concentrated in coastal regions with robust economies that are connected to international trade.

Why did the Atlantic slave trade increase in the 1700s?
The Atlantic slave trade, which involved the transportation of enslaved African people to the Americas, increased significantly in the 1700s due to a number of factors.
One factor was the increasing demand for labor in the Americas. As European colonizers established plantation systems in the New World, they needed a large workforce to cultivate and harvest crops such as sugar, tobacco, and cotton.
The indigenous populations of the Americas had been devastated by diseases brought by the Europeans, so there was a shortage of labor. As a result, the slave trade became an important source of labor for the plantations.
Another factor was the expansion of European colonies in Africa. European powers such as Portugal, Spain, the Netherlands, and Britain established trading posts and colonies in Africa, which allowed them to more easily capture and transport enslaved Africans to the Americas.
Finally, advances in transportation and communication also contributed to the increase in the slave trade. The development of faster and more efficient ships made it easier to transport large numbers of enslaved people across the Atlantic Ocean, while the expansion of European trading networks facilitated the sale and exchange of enslaved people.

Sedimentary rocks are the most common rocks exposed on Earth’s surface but are only a minor constituent of the entire crust, which is dominated by igneous and metamorphic rocks. Sedimentary rocks are produced by the weathering of preexisting rocks and the subsequent transportation and deposition of the weathering products.
a) The mode of formation of sedimentary rocks is lithification-:
To begin, existing rocks are eroded and weathered, which entails the physical breakdown of the rocks and the subsequent transfer of the debris away from the original rock.Sediments are frequently created as a result of chemical degradation caused by rainfall or dissolution. As most sediments are carried by wind or flowing volumes of water such as rivers or glacial ice, gravity plays a significant role in assisting transportation.The sediments begin to deposit once they have been transported. When subjected to an appropriate temperature and air pressure, slit deposition can also occur as a result of precipitation. Sedimentary rocks like organic reefs are one example.Once the sediments begin to deposit, layers of these sediments begin to pile up on top of one another in a process known as burial.Through the process of lithification, these sediments become compacted and cemented into solid rocks once they reach a particular depth. Sedimentary rocks are created in this manner. Chalk, clay, flint, and shale are some of the most prevalent sedimentary rocks.b) Characteristics of sedimentary rocks
Sedimentary Rocks have mud cracks.
These rocks house beddings that are of different sizes ranging from thin laminas to the thick stratas.
Sedimentary rocks have more fossils i.e. the remains of living organisms in their rock layers.
They have a different color which primarily ranges from white to red.
The raindrops leave marks on sedimentary rocks known as rain prints. Similarly, the rocks that travel with water feature ripple marks.
c) Types of sedimentary rocks
Organic Sedimentary Rocks
This rock type mainly consists of coal and limestones, which are formed due to the accumulation and deposition of dead plants and animals in rock layers.
Clastic Sedimentary Rocks
This type of rock is formed when rock layers are formed due to the mechanical weathering of different rock types.
Chemical Sedimentary Rocks
This type of rock is created when minerals that are present in rock forms undergo a chemical reaction that causes them to cool as precipitates over time before changing back to rock form.
d) Examples of sedimentary rocks
Coal, Limestone, Dolomite, Chert, Flint, Gypsum, Rock Salt

Floods are the most frequent type of natural disaster and occur when an overflow of water submerges land that is usually dry. Floods are often caused by heavy rainfall, rapid snowmelt or a storm surge from a tropical cyclone or tsunami in coastal areas.
The troposphere is the lowest layer of Earth's atmosphere. Most of the mass (about 75-80%) of the atmosphere is in the troposphere. Most types of clouds are found in the troposphere, and almost all weather occurs within this layer.
The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Temperature decreases with height throughout the mesosphere.
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away.

which plate boundary is not associated with volcanoes? group of answer choices continent-continent convergent boundary ocean-ocean convergent boundary ocean-continent convergent boundary divergent plate boundaries
Volcanism is not connected to continental convergent borders. Here option A is the correct answer.
Normally, volcanoes do not originate at transform borders. This is due, in part, to the fact that there is little to no magma present near the plate border. The iron/magnesium-rich magmas that form basalts are the most prevalent along productive plate edges.
The majority of the volcanoes are found in these geologically active borders. Divergent and convergent plate boundaries are the two types of plate boundaries that are most likely to result in volcanic activity.
Volcanoes are created by subducting plates. Subduction at a convergent plate boundary is the cause of many of the volcanoes in the world. The release of pressure leads to melting along divergent plate borders. Long fissures or breaks in the earth cause lava to flow.
