<u>The troposphere: </u>
H. This layer can have thunderstorms or clear, sunny skies.
A. The biosphere interacts most with this layer.
<u>The stratosphere:</u>
B. It is the second layer from Earth's surface.
G. Winds are strong and steady in this layer.
<u>The mesosphere:</u>
E. It is heated by the ozone layer beneath it.
D. This layer is where most meteor showers occur.
<u>The thermosphere :</u>
F. It contains the ionosphere and exosphere.
C. It contains layers of single, unmixed gas.
<u>Explanation:</u>
Depending on the Earth's temperature the atmosphere can be separated into layers. The troposphere, the stratosphere, the mesosphere and the thermosphere are those layers. The lowest layer is named as Troposphere (0-10 km from the Earth outer surface), it comprises about 75% of the atmosphere's total air and nearly most the water vapor.
Stratosphere (10-30) includes much of the surface ozone. The change in height temperature arises as this ozone absorbs ultraviolet (UV) radiation from the sun. The temperature in Mesosphere (30-50 Km) declines again with height, hitting a minimum of about -90 ° C at the "mesopause." Above this thermosphere (50-400 Km) is settled which is a area where temperatures rise with height once again. The penetration of intense UV and X-ray radiation from the sun induces this temperature rise.
Answer:
Do not try to re-light or handle malfunctioning fireworks. Soak both spent and unused fireworks in water for a few hours before discarding.
<span>The correct answer is b. Boiling point, why? because the liquid sample of napthalene is heated and remained at the temperature of 218 degrees celsius, the outcome was that the napthalene was completely vaporized, therefore we are given the scenario that at the temperature of 218 degrees celsius is considered to be the boiling pont of napthalene.</span>
The new fossil i.e, Fossil B (2,000 year old) contains more carbon-14 than the old fossil i.e, Fossil A (5,000 years old ) does.
<h3>What are Fossils ?</h3>
Fossils are the preserved left materials of ancient organisms in trace form.
Fossils are not just the remains of the organism But also the rocks.
Carbon 14 works to analyse the period organic remains that are between 100 years old (minimum) and about 50,000 years old, (maximum).
If it is new, than not enough time has passed for radioactive decay to produce and if it is older than that, the amount of radioactive decay has dropped so less amount which means that anything beyond 50,000 years old becomes gibberish and may lead to high or low (usually low) concentration.
Hence,the new fossil Fossil B (2,000 year old) contains more carbon-14 than the older Fossil A (5,000 years old ) does.
