Pumice is volcanic rock formed from frothy lava. It will usually float on water because of all the gas bubbles in it.
The solid form of lava that is frothy when it reaches the surface is called pumice. Pumice is a light, porous volcanic rock formed when lava cools rapidly and gas bubbles are trapped within it, resulting in its characteristic frothy texture. Due to its low density, pumice can float on water and is often used in various applications, including abrasives and lightweight construction materials.
Magma that reaches the surface erupts from volcanoes, either effusively to form lava or explosively to form ash, pumice and cinders. Lava and in some cases ash will then cool to form solid rock.
No. Neptune does not have a solid surface on which a floodplain might form.
The Sun's energy is given out mainly as "electromagnetic radiation". Light is a form of electromagnetic radiation. Heat is the main form the Sun's energy has when it reaches Earth, particularly the Earth's surface.
False! The reduction in pressure causes the gasses to exsolve (come out of solution) and escape into the atmosphere, so the dissolved gas content of a magma reduces when it reaches the surface.
That is pumice.

Mountains form when the volcano reaches the surface
That is correct. When magma travels from the mantle to the crust and reaches the surface, that is a volcano.
No, because when a volcano reaches the surface of the water it forms a volcnic island not a mountain

No. Saturn does not have a solid surface.
Sedimentary rocks form on the Earth's crust, and can form metamorphic rocks when buried. Igneous rocks form under the surface, or when liquid magma reaches the surface as lava.
They can form islands: when hot lava reaches the ocean, it will harden and form an island.
Extrusive Igneous Rock.
Precipitation is any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface. It includes rain, sleet, snow, and hail. Precipitation plays a crucial role in the water cycle and is essential for sustaining life on Earth.
