Answer:
Option (4)
Explanation:
Seismic P and S waves are generated during an earthquake that has the potential to propagate through the interior of the earth. P waves are also known as the primary waves and they move in a compression and extension way in their direction of propagation. S waves are shear waves. This P waves travel faster than the S waves and can travel in both solid as well as in liquid. Whereas the S wave can travel only through solids. They get absorbed when they reach the core-mantle boundary. These two waves are helpful in determining the epicenter of an earthquake by recording the arrival of these waves.
Hence, the correct answer is option (4).
Are there choices? If there are choices what are they?
Answer: Plastic Pollution
In 1950, the world produced more than 2 million tons of plastic per year. By 2015, this annual production swelled to 419 million tons and exacerbating plastic waste in the environment.
A report by science journal, Nature, determined that currently, roughly 11 million tons of plastic make its way into the oceans every year, harming wildlife habitats and the animals that live in them. The research found that if no action is taken, the plastic crisis will grow to 29 million metric tons per year by 2040. If we include microplastics into this, the cumulative amount of plastic in the ocean could reach 600 million tons by 2040.
Shockingly, National Geographic found that 91% of all plastic that has ever been made is not recycled, representing not only one of the biggest environmental problems of our lifetime, but another massive market failure. Considering that plastic takes 400 years to decompose, it will be many generations until it ceases to exist. There’s no telling what the irreversible effects of plastic pollution will have on the environment in the long run.
[ Answer ]
1 - Command Economies
2 - Market Economies
3 - Tradition Economies
[ Explanation ]
Command Economies:
This is where production, investment and prices are all controlled and determined by the government. Command Economies are not controlled by free market. The Government decides how much a product should cost and what price they should be put for sale as.
Market Economies:
This is where the product prices and value are determined by the product keeper and/or seller. The seller decides how much they want to sell it for, not the Government. This also comes with supply and demand. Prices can increase or decrease as the seller wishes.
Tradition Economies:
This is where the economy relies on customs and history. They go by what has been done in the past and what has worked out before. Traditional Economies depend on farming, agriculture, fishing, and natural sources.
