Following are the correct options for this question:
- Build more windmills
- Develop cost-efficient solar energy
- Improve gas mileage in cars
- Reduce the use of nonrenewable energy sources
Any undesirable change occurs in the air due to addition of pollutants is called air pollution. The major air pollutants are sulfur dioxide which is released from the combustion of fossil fuels like coal, petroleum and from factories. Bedsides, sulfur dioxide dust and smokes are other pollutants. Building of more wind mills and developing low cost solar energy will reduce air pollution as they will provide clean energy and will reduce dependency on coal burning in thermal power plant. Improving as mileage in cars will also reduce emission of sulfur dioxide, hence reduce air pollution. Building of more wind mills and developing low cost solar energy are renewable source of energy, will reduce use of nonrenewable energy sources such as fossil fuels.
Answer:
B)Meteor showers are visible only in the northern hemisphere as the comets orbit over the Earth.
Explanation:
Meteor showers are visible only in the northern hemisphere as the comets orbit over the Earth. Stars and constellations appear throughout the sky, in both hemispheres. Meteors are visible everywhere, although some showers are more visible in certain parts of the night sky at specific times during the year.
The feature of Wegener's idea of continental drift contributed to its rejection by the scientific community is that Wegener proposed that gravitational forces from the Sun and Moon could move continents. Read below about Wegener's idea of continental drift.
<h3>What is Wegener's idea of continental drift?</h3>
Alfred Wegener proposed that the continents were at sometime united into a single supercontinent named Pangaea, meaning all earth in ancient Greek. He posited that Pangaea broke up long ago and that the continents then moved to their current positions. He called his hypothesis continental drift.
Therefore, the correct answer is as given above

(A) A and B are the two letters that represent gulfs.
<h3>
What are gulfs?</h3>
- A gulf is a large inlet from the ocean into the continent, usually having a narrower opening than a bay, however, this is not always the case in all geographical places thus named.
- The term gulf was traditionally applied to huge, indented areas of saline water surrounded by a coastline.
- Many gulfs, including the Persian Gulf, Gulf of Mexico, Gulf of Finland, and the Gulf of Aden, are important shipping lanes.
- The United States Gulf Coast, often known as the Gulf South, is the coastline that runs along the southern United States where it meets the Gulf of Mexico.
Therefore, (A) A and B are the two letters that represent gulfs.

Answer: Higher rents causing displacement of existing residents.
Explanation:
Gentrification is the process of remodeling a neighborhood, street or building to increase its value and attract a population of a higher social status.
This process is highly controversial since the current inhabitants of the area usually cannot bear the costs of continuing to live in the same neighborhood and must move. Residents are sometimes forcibly evicted before remodeling.
