Concetti Chiave
- An orbit is the path a body follows as it revolves around another, such as Earth's path around the sun.
- The concept of orbit extends to a figurative sense, indicating a sphere of influence or interest.
- The atmosphere consists of gases surrounding Earth or other celestial bodies, affecting environmental conditions.
- Greenhouse gases in Earth's atmosphere trap heat, impacting climate over varying time spans.
- The stratosphere is a stable atmospheric layer with minimal temperature variation, also used figuratively to denote high levels.
Indice
Orbit
An orbit is the circular or oval¬shaped path that a body follows as it revolves around another body, like the Earth’s revolution around the sun or electrons’ movement around an atomic nucleus. To orbit means to travel around something in a curved path.
The first satellite to orbit the Earth was the Russian satellite Sputnik 1, which was launched in 1957 and burned up as it fell from orbit in 1958.
Planets are not the only celestial bodies that orbit the sun; comets also revolve around the sun, but while the orbits of planets are regular, the orbits of comets are highly irregular.
Orbit can also be used in a figurative sense to refer to a sphere of influence, interest, or activity.
In my opinion, the best film of the year is an independent production directed by a filmmaker who is outside the orbit of the mainstream film scene, but unfortunately the film has not had the exposure it deserves because it has been on limited release in cinemas.
I'll attempt to help you with your problem with the local school, but education matters are out of my orbit. If nothing else, I can put you in contact with the council education board.
Atmosphere
The atmosphere is the mass of air surrounding the Earth, or the mass of gases surrounding any other planet or star. In a figurative sense, atmosphere refers to the feel that a certain place has or its environment, or to the air of a given location.
Greenhouse gases are those gases that trap heat in the Earth's atmosphere. They remain in the atmosphere for different amounts of time, ranging from a few years to thousands of years.
Noelle did not like her new job very much. Her colleagues were not very friendly, and everyone was very competitive, which made for a very tense atmosphere in the office.
The stratosphere is a part of the Earth's atmosphere that is characterized by little vertical change in temperature. Stratosphere is also used figuratively to speak of the highest levels of a profession, of prices, or of other quantities.
The stratosphere is the second major region of the atmosphere, located between the troposphere and the mesosphere.
Michael would like to buy a house in the city, but in recent years home prices have launched into the stratosphere so he doubts he can find something that he can afford.

Una órbita es el camino circular o ovalado que un cuerpo sigue al girar alrededor de otro cuerpo. Ejemplos mencionados incluyen la revolución de la Tierra alrededor del sol y el movimiento de los electrones alrededor de un núcleo atómico.
El primer satélite en orbitar la Tierra fue el Sputnik 1, lanzado por Rusia en 1957, y se desintegró al caer de su órbita en 1958.
Los gases de efecto invernadero son aquellos que atrapan el calor en la atmósfera de la Tierra, y su característica principal es que permanecen en la atmósfera durante diferentes periodos de tiempo, desde unos pocos años hasta miles de años.
La estratosfera es una parte de la atmósfera de la Tierra caracterizada por poco cambio vertical en la temperatura. Figuradamente, se usa para referirse a los niveles más altos de una profesión, precios u otras cantidades.
