Answer:

The correct statement for comet is - ( a ) They have highly elliptical orbits around the sun

Explanation:

The comet is made up by the composition of dust , water , ice , rock and frozen gases like , the carbon dioxide , methane , ammonia and carbon monoxide .

Comet shows a process called outgassing , i.e. , the comet passes close to the sun , then they start to release gases , which is visible in the form of a comet's tail .

The comet and its tail glows by the sun and becomes visible when the comet passes through the solar system , because the dust partials reflects sunlight directly and the gas glows due to ionization process.

The orbital of comet is usually highly eccentric elliptical path .

The model clarifies how a group creates after some time and every one of the stages are considered as fundamental variables which are basic for the advancement of a gathering. As needs be, Group improvement is set apart by the accompanying stages:

Forming and mutual acceptance :

Common acknowledgment is the main stage in a gathering's improvement where the emphasis is on the relational relations among the individuals. Normally, Members evaluate each other with respect to reliability, passionate solace, and acknowledgment and resolve their underlying clashes over power and expert so as to go to a basic leadership process.

Storming and decision making :

Arranging and basic leadership happen during the second phase of a gathering's advancement. this is the arranging stage that incorporates characterizing the errands and how to achieve them-who will be pioneers and by what means will individuals impart and organize with one another over an assignment?

Motivation and contentment :

The accentuation is on execution and accomplishment, by addressing and nudging too through help and sharing of work.

During El Niño, what happens to the coastal marine ecosystems near Peru? They thrive. Their productivity increases. They collaps
agasfer [191]

Answer:

<u>1. Their productivity increases, 2. increased friction with the land surface, 3. They intensify, 4. It increases evaporation.</u>

Explanation:

  • When the El Nino a southern oscillation reaches the Peru coast it upwells warm water and which is beneficial to the fishes and marine life. As the upper water planktons depend on this nutrient-rich water and thus thrive and increase in productivity.
  • Its a fact that the cyclones drive their energy from the warm moisture supply of water from the oceans and seas and when they make a landfall they collapse and they can't move to the interior as the friction a force and the number of energy decreases and thus they fall.
  • When the tropical cyclones form in the warm waters they intensify and grow bigger in size and thus move further quickly.
  • As the sea sprays are salts that are ejected from the oceans they are a process of heat transfer and intensify the formation if a cyclone, transferring heat, momentum, and moisture into the air.

​The following question refers to the temperature and dew point data in the following cities.
Lyrx [107]

Answer:

a. City A

Explanation:

City A has the highest saturation vapor pressure among other cities because it has highest temperature and dew point as compared to another cities. Temperature is related to saturation vapor pressure, if increase in the temperature occurs, the average energy of the particles is also increases. It means that more particles have enough kinetic energy to escape from the surface of the liquid as a result it increase the saturated vapor pressure and the region has the highest saturation vapor pressure.
