Answer:
1 A. Body waves are described as compressional or shear
2 A. S-waves and C. P-waves
3 A R-waves and C. L-waves
Explanation:
Body waves are usually compressional or shear waves. The compressional wave, there is a push and pull in the direction of the propagating waves resulting in compression. shear waves involves transverse motion perpendicular to the direction of propagation.
S-waves are known as shear waves and p-waves are known as primary waves or compressional waves. Both are Body waves.
L-waves are called love waves and R-waves are called Rayleigh waves. Both are types of surface waves which are far more destructive than body waves.
Well dumping is a method, waste materials are dumped in open low labs away from the city.
Answer:
D). Combat the overuse of asphalt and concrete surfaces.
Explanation:
Urban Heat is characterized as the circumstance in which a particular urban area has a considerably increased temperature because of specific human activities. As per the question, the most adequate strategy to assist a city in fighting the battle against the increasing 'urban heat island' would be to '<u>avoid the excessive use of surfaces made of concrete and asphalt</u>.' The key reason behind this is that 'asphalt and concrete surfaces tend to possess an extremely higher heating capacity' and thus, it absorbs heat from the sun and causing the land temperatures to reach higher till 60° celsius. Therefore, preventing the overuses of such surfaces would be the most adequate strategy to keep the temperatures in control. Hence, <u>option D</u> is the correct answer.
B I s the right answer good luck
