Concetti Chiave
- An orbit is the path a body follows around another, such as Earth's rotation around the sun, with comet orbits being irregular compared to planets.
- Orbit is also used metaphorically to describe a sphere of influence or activity, like a filmmaker outside mainstream cinema.
- The atmosphere consists of gases surrounding Earth or other celestial bodies, and can metaphorically describe the mood of a place.
- Greenhouse gases trap heat in Earth's atmosphere, remaining for varied durations, affecting climate change.
- The stratosphere, part of Earth's atmosphere, is used metaphorically to describe high levels in various contexts, such as soaring house prices.
Indice
What is understanding orbits?
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.
Figurative use of orbit
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 and its meanings
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.
Stratosphere in science and metaphor
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.
Domande da interrogazione
- What defines an orbit in both literal and figurative contexts?
- How do comets' orbits differ from those of planets?
Literally, an orbit is the path a body follows as it revolves around another, such as Earth's path around the sun. Figuratively, it refers to a sphere of influence or activity, like a filmmaker being outside the mainstream film scene's orbit.
While planets have regular orbits around the sun, comets have highly irregular orbits, making their paths less predictable.
