Main features of Solar System, Main facts of solar system

iren [92.7K]

Answer:

The main features of the solar system:

The Sun is our nearest star.

The planets orbit the Sun.

The time taken to orbit the Sun increases with distance from the Sun.

Gravity keeps the planets in orbit around the Sun and the moons in orbit around their planets.

From the Sun, the order of the planets is Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. You might need to be able to recall this in the exam.

The planets go around the Sun in slightly squashed circular elliptical orbits.

Pluto is classified as a dwarf planet or planetoid. It has a highly elliptical or eccentric orbit.

Main facts

The definition of a planet and a moon is fuzzy. ...

Comets and asteroids are leftovers. ...

The planets are all on the same “plane” and orbit in the same direction. ...

We're nowhere near the center of the galaxy. ...

But the Solar System is bigger than you think. ...

The Sun is hugely massive. ...

Which of the following is an example of a closed system?

Yakvenalex [24]

Answer: B

Explanation: A closed system can be defined as a system that does not allow for an exchange of matter with its surroundings.

An estuary where fresh water and ocean water mix is not a good example of a closed system because fresh water and ocean water mix out in the open and matter is exchanged.

A living single-called organism such as phytoplankton does not constitute as a closed system because in order for the phytoplankton to be considered alive it needs to interact with its surroundings i.e light from the sun so photosynthesis (converting light energy into chemical energy to be used by organism) can occur. This also happens out in the open

A river that flows into the ocean does not fit into the closed system definition. This is because a river that flows into the ocean allows for itself (matter) to mix with that of the ocean in an open space (rivermouth).

Therefore option B is the answer because it fits the definition. A chemical reaction within the deep ocean organisms that allows them to glow happens within (inside) the organism, making this system closed, hence there is no exchange of matter with surroundings.
