True.
Edit:
Unfortunately, even today, we can't be sure about the cores of the gas giants.
The Sun and other stars do not normally have a "solid" surface, but the density at a point within the star is greater than most "solid" matter. The term for material existing in this high-energy state (although very dense for ionized gas) is "plasma". Certain types of stars lose may their fusion reaction, collapsing into a "neutron star", with a very dense fluid surface, and a crushingly high gravity.
no it is false
true or false, maria are flat areas , once flooded with lava , on the moon's surface
Jovian planets can also be called gas giants. They are Jupiter, Saturn, Neptune and Uranus. They are mostly made up of gas, but they have a rocky core, (somewhere!). They are said to lack a solid surface, But they actually don't really have a surface at all! The gases that they're made up from get thinner and thinner as you get closer to the core.
Totally false its now moon and mars too which have water on their surface....Even the Saturn rings connsists of frozen water i.e. ice. So earth is not only the planet.
False. The outer planets are gas giants (although they have a solid core). The inner planets are 'rocky'.
true
It is not true.
true or false? the crust is the earths only solid layer or part
The statement, "not every walking or working surface can be a potential fall hazard," is false.
Yes, sublimation is a change from solid to gas.
False
false !
no it does not
True
That statement is true.
true
