Natural levees are created during  floods . Correct option (c).

Troposphere and mesosphere  two atmospheric layers Correct option (a)

weathering  is not exogenic in nature. Correct option (c)

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.

A saturated, spongy, and impermeable layer or stratum is what the phrase defines as an aquifer.

An aquifer is a rock that contains water and easily transports it to wells and springs. The aquifers can be penetrated by drilling wells and then filled with water. Rainfall replenishes the aquifer's permeable sandstone with water over time.

Stormwater, which is produced by precipitation and snowmelt, seeps into the earth until it reaches layers of rock formation, where it is trapped and stored underground, filling aquifers. The permeable rocks of aquifers are refilled by rainwater that seeps into the soil.

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.

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.

If the Earth absorbs all the incident energy, it is likely that the Earth's surface and atmosphere will heat up significantly. The Earth's surface and atmosphere absorb a portion of the energy from the sun's rays, which helps to keep the planet warm and habitable for life. However, if the Earth absorbs all of the incident energy, it could lead to an increase in the Earth's temperature, which could have negative consequences for life on the planet.

Some potential consequences of the Earth absorbing all the incident energy could include:

Global warming: An increase in the Earth's temperature could lead to global warming, which is the long-term warming of the planet due to an increase in the concentration of greenhouse gases in the atmosphere. This could lead to rising sea levels, more frequent and severe heatwaves and storms, and changes in weather patterns.

Damage to ecosystems: A significant increase in the Earth's temperature could lead to changes in the distribution and behavior of plants and animals, which could have negative impacts on ecosystems around the world. For example, warmer temperatures could lead to the spread of invasive species, while also stressing or killing off native species that are adapted to cooler temperatures.

Negative impacts on human health: Higher temperatures could lead to increased heat-related illnesses, such as heatstroke and dehydration, as well as increased air pollution and other environmental health risks.

Therefore, it is important for the Earth to absorb a balanced amount of incident energy, rather than all of it.

The option that best describes the effect of the spread of Islam on Indian Ocean trade is that A.

It led to the expansion and intensification of commerce along already existing trade routes.

Another reason of the rapid growth of Islam was the increase in trade. Not like early Christianity, Muslims were not resistant to contribute in the trade and profit; Muhammad(S.A.W) himself was a merchant.

As new regions came under the orbit of Islamic civilization, this given specific religion provided merchants with a safe and sound way for trade.The Indian Ocean marketplace is a series of economic exchanges in the regions of East Africa, Arabian Peninsula, India, and China that played a big role in the spread of Islam.

The concept of religion was just one of the ideas that flowed with the travelers, traders, and goods of the Indian Ocean. Shared religious belief may increase trust and therefore lessen transaction costs between trading partners. This effect should be particularly important for goods that are sensitive to trust.

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.
