An example of a renewable resource is option A; hydroelectricity
Coal is an example of a nonrenewable resource. Hence option C is correct.
What is Natural resources?The water in rivers and streams is filled naturally by precipitation, snowmelt, and groundwater, making it a sustainable and inexhaustible source of strength.
Coal is a hydrocarbon deposit that formed over heaps of years from the remains of old plants and animals. Once bitumen is extracted and charred, it cannot be replaced or regenerated inside a human timescale. This makes it a restricted and nonrenewable source of strength.

According to Stevens the intensity of a sensation is:
A) directly proportional to the intensity of the reflected sound-wave.
B) decreased as the intensity of the physical stimulus increases.
C) directly proportional to the intensity of the physical stimulus raised by a constant power (exponent).
D) directly proportional to the logarithm of the intensity of the physical stimulus raised by a constant power.
Stevens says that the intensity of a feeling is: decreased as the physical stimulus became more intense.
Option B is correct.
How does an electric field work?The force per unit charge that is applied to a positive test charge that is at rest at that location is represented by the electric field, which is described mathematically as a vector field that can be connected to any point in space. An electric field can be created by either the electric charge or time-varying magnetic fields.
What is intensity ?The intensity (I) of a wave is determined by dividing the surface area over which the energy is dispersed by its rate of energy transfer. To put it another way, intensity refers to the rate of energy flow per unit area. The amount per unit region is estimated by force. Intensity is typically used to describe the size of waves per unit area. Another way to think about a wave's strength is its power per unit of area over time.
Therefore, Stevens asserts that the intensity of a sensation is as follows: diminished as the force of the actual improvement increments.

6.1.6 Quiz: Characteristics of Ecosystems
The plant shown in the photo is a vine. It can grow where
there are many other plants and plenty of water year-
round.
The correct option is (C) Rain forest. The type of ecosystem that is more likely to have a large number of vines that can grow where there are many other plants and plenty of water year-round is a rainforest.
Rainforests are among the most biologically different ecosystems on Earth, home to millions of species of shops and creatures, numerous of which are set up nowhere differently. Vines are an important element of the rainforest ecosystem, serving as a source of food, sanctum, and niche for numerous creatures.
Some exemplifications of common rainforest vines include lianas, which can climb up to the cover of trees and give a ground for creatures to cross from one tree to another, and epiphytes, which grow on trees and can give a home for insects, catcalls, and other brutes. still, rainforests are under trouble from deforestation, niche destruction, and climate change.

The correct option is D.
What is hydropower?Hydropower, or water power, is the process of using falling or swiftly moving water to generate energy or drive machinery.
This is accomplished by generating electricity from a water source's gravitational potential or kinetic energy which turns a turbine to generate electricity.
Hydropower is means of producing sustainable energy as the energy is clean and does not lead to pollution of the environment.

A particular region has experienced increased deforestation. This has led to an increase in soil erosion, which has caused a decrease in the overall soil quality of the region due to the loss of fertile topsoil. Farmers in the area have had difficulty growing crops in the less fertile soil that is left behind, which has negatively impacted the region's economy. Which of the following solutions would best help reduce soil erosion and improve soil quality in the region? A. switching to organic fertilizers and allowing grazing by domesticated animals in fields not currently used for crop cultivation B. increasing the vegetative cover in the region and using sustainable farming techniques such as terrace cultivation C. switching to synthetic fertilizers and using aggressive agriculture techniques such as slash-and-burn farming D. adding small amounts of phosphate and other chemicals to the remaining soil before planting crops
Increasing the area's vegetative cover and utilizing Sustainable Farming techniques like terrace cultivation will have the greatest impact on reducing soil erosion and improving soil quality. So, the answer is B
What is Soil Erosion?The natural process of dirt being taken out of one place and carried to another by wind, water, or other forces is known as soil erosion. It is a natural occurrence that has been going on for millions of years, but in recent years it has increased because of human actions including deforestation, overgrazing, and bad land management techniques. It can be reduce by increasing the area's vegetative cover.
What are Sustainable Farming Techniques?Sustainable farming methods are agricultural practices that aim to protect biodiversity, limit the use of synthetic pesticides and fertilizers, improve soil health, and conserve water. Crop rotation, cover crops, integrated pest management, and terrace cultivation are few examples of sustainable agricultural methods.It is highly recommended to use the terrace farming method,which involves planting crops on graduated terraces carved into the slope on the slopes of hills or mountains.

Landslides, sand dune building, and water erosion of canyons may all result in devastating alterations to the Earth's surface.
What is Earth's surface?The outermost layer of the planet, which is referred to as the Earth's surface, is made up of the atmosphere, the solid ground, and various bodies of water. A range of natural factors, including weathering, erosion, and tectonic activity, affect the Earth's surface, making it a dynamic and ever-changing system. Human activities such as pollution, climate change, and changes in land use all have an impact on it.
Canyons are shaped and widened by the process of water erosion, which is the process by which water running through a canyon wears away the surrounding rock and soil. This process may be detrimental since it can result in the loss of land and ecosystems, changes to the landscape, and other negative effects.
When soil, rock, or other material on a slope becomes unstable and falls downhill, a land slide occurs. This has the potential to seriously harm the environment, property, and infrastructure.
When wind transports sand particles and places them in a particular area, dunes are formed. This process is known as sand dune building. Sand dunes can be natural and play a significant ecological role, but too much sand accumulation can be harmful since it can bury plants, habitats, and infrastructure.
