Jupiter, Saturn, Uranus and Neptune are referred to as the Jovian Planets, or planets that are essentially big balls of gas, each are surrounded by many moons and rings.
Unlike Terrestrial Planets like the Earth, these planets lack solid surfaces and they have relatively small, dense cores that are surrounded by layers of gas, which is made mostly of hydrogen and helium.
Jupiter and Saturn is different from Uranus and Neptune because the first pair is made almost entirely of hydrogen and helium and some hydrogen compounds, while the latter pair are made primarily of hydrogen compounds with smaller traces of hydrogen, helium, metal and rock.
As for the planets' interior, both Jupiter and Saturn have layers of metallic, liquid and gaseous hydrogen extending outward, topped with a layer of visible clouds.
On the other hand, Uranus and Neptune have cores of rock, metal, water, methane and ammonia. The layer surrounding the core is also made up of hydrogen that is covered with a layer of visible clouds.
Answer:
Globalisation of Culture refers to the growth and spread of material culture from the place of origin to far and wide around the globe.

Answer:
d). It is easier to make a large reflecting telescope than a large refracting telescope.
f). A reflector can collect more light than a refractor.
Explanation:
A telescope is a device that is used to observe distant objects by the use of lenses and mirrors. It is also used to observe different distant objects by their reflection, absorption, emission or the reflection of the electromagnetic radiations.
Most of the professional telescopes are reflectors because :
1. The reflected telescope is able to receive more of the light when it reflects all the light falling on surface. And it is easier for making a large telescope rather then making large lenses for the refracting telescope. So it is easier to make large reflecting telescope than a large refracting telescope.
2. A reflected telescope receives all the wavelength of the light and it reflects all the light falling on the surfaces where it is refracted telescope that contains lenses cannot absorbs all the light and causes the chromatic aberration.
Answer:
Polar bear viewing tourists perceive climate change to be negatively impacting polar bears
Explanation:
Polar bear viewing tourists perceive climate change to be negatively impacting polar bears but do not necessarily understand how they themselves contribute to GHG emissions, or understand offsetting possibilities. The polar bear viewing industry is estimated to contribute 20,892 t/CO2 per season.
