Define the atmosphere and explain the importance thereof

1 answer:

6 0

An atmosphere is the layers of gases surrounding a planet or other celestial body. ... These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure.

The Earth's atmosphere protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.

Earth's atmosphere is a thin blanket of gases and tiny particles: together called air. We are most aware of air when it moves and creates wind.

Compare earth and mars in paragraph plz

Studentka2010 [4]

Answer:

Hey buddy, here is your answer. Hope it helps you.

Explanation:

Atmospheric pressure and temperatures are another way in which Earth and Mars are quite different. Earth has a dense atmosphere composed of five main layers – the Troposphere, the Stratosphere, the Mesosphere, the Thermosphere, and the Exosphere. Mars' is very thin by comparison, with pressure ranging from 0.4 – 0.87 kPa – which is equivalent to about 1% of Earth's at sea level. When it comes to magnetic fields, Earth and Mars are in stark contrast to each other. On Earth, the dynamo effect created by the rotation of Earth's inner core, relative to the rotation of the planet, generates the currents which are presumed to be the source of its magnetic field. The presence of this field is of extreme importance to both Earth's atmosphere and to life on Earth as we know it.In terms of their size and mass, Earth and Mars are quite different. With a mean radius of 6371 km and a mass of 5.97×1024 kg, Earth is the fifth largest and fifth most-massive planet in the Solar System, and the largest of the terrestrial planets. Mars, meanwhile, has a radius of approximately 3,396 km at its equator (3,376 km at its polar regions), which is the equivalent of roughly 0.53 Earths. However, it's mass is just 6.4185 x 1023 kg, which is around 15% that of Earth's.Earth and Mars are similar when it comes to their basic makeups, given that they are both terrestrial planets. This means that both are differentiated between a dense metallic core and an overlying mantle and crust composed of less dense materials (like silicate rock). However, Earth's density is higher than that of Mars – 5.514 g/cm3 compared to 3.93 g/cm3 (or 0.71 Earths) – which indicates that Mars' core region contains more lighter elements than Earth's.

what occurs during the process of group development and What factors contribute to the facilitation of group development

aleksandrvk [35]

Answer and Explanation:

Bruce Tuckman's forming, storming, norming, and performing model portrays the phases that fill in as an accommodating apparatus in understanding the procedure of improvement of a gathering. 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 :

In the third phase of advancement, the Members' consideration is coordinated to self-inspiration and the inspiration of other gathering individuals for the achievement of the changed assignments. The accentuation is on execution and accomplishment, by addressing and nudging too through help and sharing of work.

Performing :

This is the last phase of improvement wherein a gathering has turned into a developed, compelling, effective and beneficial unit. The gathering is said to have built up express and verifiable standards for the individuals, has portrayed a hierarchy of leadership and every one of the gathering individuals get their specific novel commitments the type of a point of view, an expertise, or an asset to the group.
