The types of seismic waves are confined at the surface are
- Rayleigh waves
- Love waves
<u>Explanation:</u>
Rayleigh wave are having the motion of retrograde particle which is confined to the vertical plane of the motion. Love wave are having the motion which is transverse which is confined to horizontal plane of the motion. If we talk about other mentioned waves than P waves, S- waves all travel in different pace from slow to fastest. S-waves travel in slow pace whereas p-waves are called the fastest. Disperse waves also travel in a decent speed
World War I and II. These wars caused lots of economic growth and development because there was a pressure to create better inventions. Having better technology could mean the win or lose of a war. :D
Explanation:
In Lima, the capital of Peru, the climate is very peculiar: it is subtropical desert, with a warm season from December to April and a cool, humid and cloudy season from June to October, with May and November as transitional months.
The statement "Mass extinctions have occurred several times on Earth" explains the indication of the fossil record.
<h3>Indication of Fossil fuels:</h3>
Paleontologists are fascinated by the evolution and extinction of fossil species throughout geologic history. To do so, they look at all the fossils that have been preserved in sedimentary rocks.
The fossil record is what we call it. Paleontologists have been collecting fossils from sedimentary rock layers all over the world for over two centuries.
Their goal is to figure out how species have evolved over geologic time. It can be used as a geologic timescale once the succession is established.
Then, if a specific fossil is discovered in a rock, you can determine where it belongs on the geologic timescale.
Therefore, the correct option is the third sentence.

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.
