42. What happens to seismic waves as they travel through materials of differing
rigidities?

Answers

Answer 1

Answer:

Shadow zones exist because the materials that make up Earth's interior are not uniform in rigidity. When seismic waves travel through materials of different rigidity, they change in both speed and direction. S waves do not reach the S wave shadow zone because cannot pass through the liquid outer core.

Answer: The media plays a huge role in our society. The media has the power to greatly influence its viewers. For example the media can claim that subways tuna is not fish and people believed it (this actually happened). The media plays the role similar to a mirror. Mirrors show reflection and society typically copies whatever they hear or see the media doing. The media's job is to influence our daily lives and give us routines.

Identify the true statement. Choose one: A. The troposphere is the highest layer within the homosphere and sits below the mesopause. B. The mesosphere is ozone-rich and convects as warm air rises and cold air sinks. C. The thermosphere has distinct layers of gases of different densities and therefore is called the heterosphere. D. Ozone is a trace gas that protects the Earth's surface from excessive infrared radiation.

Answers

Answer:

D

Explanation:

The following statement which is true is:

Ozone is a trace gas that protects the Earth's surface from excessive infrared radiation.

Thus, option 'D' is the correct option.

What is the ozone layer?

The majority of the UV light from the Sun is absorbed by the Earth's stratosphere's ozone layer, also known as the ozone shield. Compared to other areas of the atmosphere, it has a high concentration of ozone, yet it is still relatively low in comparison to other gases in the stratosphere.

The typical ozone concentration in the Earth's atmosphere is around 0.3 parts per million, whereas the ozone layer has a concentration of fewer than 10 parts per million. Although its thickness fluctuates seasonally and geographically, the ozone layer is mostly located in the lower stratosphere, from about 15 to 35 kilometers (9 to 22 mi) above Earth.

How far is it from March to June?​

Answers

3 months between march to june

From March to June, there are three months, so it is a span of approximately 90 days or a quarter of a year. The exact number of days can vary depending on the specific calendar year and any leap days within that period.

Leap days, occurring in the Gregorian calendar, are additional days added to February every four years to synchronize the calendar with Earth's orbit around the sun.

This adjustment accounts for the fact that a complete orbit takes about 365.2425 days. Leap years, such as 2020 and 2024, have 366 days instead of the usual 365.

Leap days help to maintain the alignment of seasons and prevent the gradual shifting of dates. They play a crucial role in ensuring that our calendar remains accurate and aligned with astronomical cycles, promoting long-term consistency and reliability in timekeeping.
