Using radiometric dating, which evaluates the ratio of two distinct isotopes in a sample, the age of rocks can be ascertained.

The required details for radiometric dating in given paragraph

Radiometric dating, radioactive dating, or radioisotope dating is a technique used to date materials, such as rock or coal, into which trace amounts of radioactive contaminants have been selectively incorporated during their formation. The method compares the abundance of a naturally occurring radioisotope in a material to the abundance of its decay products, which form at a known decay rate. The use of radiometric dating was first published by Bertram Boltwood in 1907 and is now the primary source of information on the absolute ages of rocks and other geological features, including the age of fossil life forms or the age of the Earth itself wide range of natural and artificial materials to date. In addition to stratigraphic principles, radiometric dating methods are used in geochronology to construct geologic time scales.

By allowing the establishment of geological timescales, it is an important source of information about the age of fossils and the rate of evolutionary change derived from them. Radiometric dating is also used to date archaeological material, including ancient artifacts.

A subsistence farmer in the Amazon River basin in Brazil who practices slash-and-burn farming will  most likely to locate his crops near the forest for easy access to newly cleared land.

Hence, the correct option is D.

Slash and burn cultivation is a method of farming which involves clearing of all trees and plants on a land by burning, and cultivating crops for a short time interval then moving to another clear land for same purpose. Farmers believed that the yields increase after using this method but on the other hand it is exhaustive for the environment. After the soil looses its fertility the cultivators move to another land which degrades the quality of land and also harm the environmental balance.

The economies of the Southern colonies were different from those of the other colonies in several ways. One of the main differences was that the Southern colonies relied heavily on agriculture, particularly the production of tobacco, rice, and indigo.

These crops were labor-intensive and required large numbers of workers, leading to the development of a system of plantation agriculture and the use of enslaved labor.

Another difference was that the Southern colonies had fewer cities and less industry than the other colonies. This was due in part to the fact that the Southern colonies had a relatively small population and a large amount of land.

The economy of the Southern colonies was also characterized by a system of trade that was centered on the export of agricultural products to Europe and the import of manufactured goods.

Overall, the economies of the Southern colonies were characterized by a focus on agriculture, the use of enslaved labor, and a system of trade that was centered on the export of agricultural products.

Scientists figured it out through indirect evidence, such as seismic activity and volcanic eruptions.

Scientists observed that earthquakes occur at plate boundaries and measured the waves generated by the earthquakes to infer the characteristics of the Earth's interior. They also analyzed the distribution of volcanoes and their chemical composition to understand the material that is being erupted from the mantle.

This data suggested that plates must be moving and interacting with the mantle in some way. Additionally, the discovery of magnetic stripes on the seafloor provided further evidence for plate tectonics, as the stripes showed that the seafloor was spreading apart at mid-ocean ridges.

By piecing together various lines of evidence, scientists were able to develop the theory of plate tectonics, which explains how and why plates move and interact with the mantle.

The interaction of light waves with water droplets, as well as the way that light refracts and disperses as it travels through these droplets, results in the development of a rainbow.

Refraction and dispersion, two physical processes that explain how rainbows arise when light waves interact with airborne water droplets. The many hues of the light spectrum divide and fan out as a result of light being refracted, or bent, when it enters a water droplet. Because each hue has a unique wavelength and moves through the water droplet at a little different speed, this occurs.

The colors further divide and form the distinctive arc of a rainbow as the light that was previously refracted is then reflected off the rear of the water droplet and refracted once more as it leaves the droplet. This is called Dispersion.

Impacting human settlements: Volcanoes can impact human settlements in a variety of ways, including destroying homes and infrastructure, displacing communities, and disrupting economies. For example, the 1991 eruption of Mount Pinatubo in the Philippines caused the evacuation of over 20,000 people, and destroyed homes and farmland in surrounding areas.

Generally, Altering topography: Volcanoes can create new landforms or modify existing ones through the deposition of volcanic materials such as ash, lava, and pyroclastic flows. For example, the eruption of Mount St. Helens in 1980 created a new dome and crater, and buried the surrounding landscape in up to 600 feet of volcanic ash and debris.

Changing hydrology: Volcanic eruptions can cause changes in the water cycle by altering the distribution and availability of water. This can include the formation of new lakes, streams, and wetlands, as well as changes in water quality and quantity. For instance, the eruption of Mount Pinatubo in the Philippines in 1991 caused lahars (mudflows) that blocked rivers and caused flash floods.

Affecting atmospheric conditions: Volcanic eruptions can release large amounts of gas and particulate matter into the atmosphere, affecting air quality and weather patterns. For example, the 1815 eruption of Mount Tambora in Indonesia caused the "Year Without a Summer," a global climate anomaly marked by cooler temperatures and widespread crop failures.

Creating new habitats: Volcanoes can create new habitats for flora and fauna, such as geothermal springs and lava tubes. These habitats can be used by organisms adapted to extreme environments, such as thermophilic bacteria and tube-dwelling insects. The volcanic island of Surtsey, off the coast of Iceland, has been designated a UNESCO World Heritage Site for its unique ecosystem.

Producing fertile soil: Volcanic ash and other materials can enrich soil with nutrients and minerals, making it more fertile for plant growth. This is why many crops are grown in volcanic regions, such as coffee in Central America and grapes in Italy's Mount Etna region.

Temperature inversions work to trap pollution when the temperature increases with height instead of decreasing. In a temperature inversion, a layer of warm air is trapped above a layer of cooler air, which acts like a lid and prevents the mixing of air and the dispersal of pollutants. This can lead to the accumulation of pollutants near the surface, resulting in increased air pollution.

Temperature inversions are more likely to occur in calm, stable weather conditions, such as clear nights with light winds, when the ground cools faster than the air above it. The trapped pollutants can cause a range of health and environmental problems, including respiratory issues, smog, and haze.

It is important to note that temperature inversions are not the only factor that can cause air pollution. Other factors, such as emissions from industrial processes, transportation, and deforestation, also play a significant role in air pollution.

The oldest rocks or structures are Precambrian sedimentary and igneous rocks. The correct answer is C.

Sedimentary and igneous rocks from the Precambrian era are the oldest rocks or formations. Igneous rock, which comes from the Latin word ignis, which meaning "fire," is one of the three main types of rocks.

Sedimentary rocks and metamorphic rocks are the other two categories of rocks. In the process of cooling and solidifying, magma or lava creates igneous rocks.

Existing materials in the mantle or crust of the earth can partially melt and turn into magma. The three mechanisms that cause melting are frequently an increase in temperature, a decrease in pressure, or a change in composition.

Extrusive rock or intrusive rock can form during the solidification of rock above or below the surface. Igneous rocks can still form into natural glasses whether or not they crystallize to produce granular crystalline rocks.
