Resources And The Environment

Explanation
Renewable resources are the correct answer because they are resources that can be naturally replenished or replaced at a rate that is equal to or greater than the rate at which they are used. This means that their supply is not depleted or exhausted, making them sustainable in the long term. Examples of renewable resources include solar energy, wind energy, water (hydro) power, and biomass. These resources are crucial for reducing our dependence on nonrenewable resources like fossil fuels, which cannot be replenished and are finite in quantity.

Explanation
The sun is the ultimate source of most forms of energy on Earth. It provides solar energy, which is converted into various forms such as heat, light, and chemical energy. Fossil fuels, biomass, and tidal power are all indirect sources of energy that ultimately originate from the sun. Fossil fuels are formed from ancient plants and animals that relied on the sun for their energy. Biomass is derived from organic materials that have stored solar energy through photosynthesis. Tidal power is generated by the gravitational pull of the moon, which is influenced by the sun.

Explanation
When populations reach the carrying capacity of the environment, it means that the resources available in the environment can no longer support further growth. This leads to a decrease in birth rates and an increase in death rates, resulting in the population stabilizing and eventually reaching a point where it stops growing. This is because the available resources, such as food, water, and space, are limited and cannot sustain a larger population.

Explanation
Photovoltaic cells are not derived from living things. Petroleum, coal, and peat are all fossil fuels that are formed from the remains of ancient plants and animals over millions of years. However, photovoltaic cells are made from inorganic materials like silicon and do not involve any biological processes. They convert sunlight directly into electricity through the photovoltaic effect, making them a sustainable and renewable source of energy.

Explanation
At the heart of mile 12 is a dump. This implies that mile 12 is a location where waste and garbage are disposed of. It suggests that the area is likely to be polluted and unsanitary, which could contribute to the issues of overpopulation and poverty mentioned in the news report. The presence of a dump in mile 12 may also indicate a lack of proper waste management and infrastructure in the area, further exacerbating the problems faced by the community.

Explanation
The pressures of an increasing population combined with a weakening economy often lead to higher levels of crime and corruption. As the population grows, there may be limited resources and opportunities available, causing frustration and desperation among individuals. This can contribute to an increase in criminal activities such as theft, robbery, and violence. Additionally, a weakening economy can create an environment where corruption thrives, as individuals may resort to illegal and unethical practices to secure their financial stability.

Explanation
The three factors that are needed to create stable cities, especially in mega cities around the world, are education, jobs, and houses. Drugs do not contribute to the stability of cities and can often have negative effects on communities, leading to social and economic instability.
