This process is known as mantle convection. The hotter, less dense magma rises while the cooler, denser magma sinks, creating a circular motion within the mantle. This movement of magma is driven by differences in temperature and density, ultimately leading to the displacement of magma at the surface.
20°C is hotter than 20°F. 20°C is equivalent to 68°F.
Within magma there are volatile gases, predominantly water, but also carbon dioxide, sulphur dioxide etc. At the pressures within a magma chamber these gases are protogases, usually incorporated into the mineral structure in some way i.e. they have the potential to become gases at lower pressures, higher up, when the magma expresses itself as a volcano, where they are released. A magma chamber is not a static repository, but as some minerals created within the magma chamber are heavier (and crystallize at a higher temperature) than others, they sink, and form heavier rocks (e.g. gabbro). The rest of the melt will rise due to being less dense than the surrounding rock, because it is hotter, contains volatiles, and has lost heavier, crystallized minerals; this process continues until the heat is spent, or it emerges as a volcano. The heat within the magma chamber has the minerals in a heightened state of excitement, therefore they will take up more space, and generally be less dense than their cold equivalents.
High temperatures are required to form magma at oceanic ridges because the mantle beneath these regions is hotter due to its proximity to the Earth's core. In contrast, the continental crust is thicker and insulates the mantle, resulting in magma formation at lower temperatures. Additionally, the higher pressure at oceanic ridges can also contribute to the higher temperatures needed for magma formation.
20 degrees Celsius is hotter than 10 degrees Celsius.
Cooler magma flows slower than hotter magma.
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
when magma is melted at a higher temp. it'll be more runny so cooler magma will be slower than hotter magma
Basaltic magma is hotter than andesitic magma. Basaltic magma typically has temperatures ranging from 1000°C to 1200°C, while andesitic magma has temperatures around 800°C to 1000°C.

Baslatic magma is hotter.
yep,
yep,
No, the color of a flame is determined by the temperature at which a material burns. Blue flames are typically hotter than orange flames because they burn at a higher temperature.

yes because lava is exposed to the surface while magma is below Earth's suface which would be hotter than the suface
Magma is hotter than lava because magma is located beneath the Earth's surface where it is exposed to higher temperatures and pressures compared to lava, which is magma that reaches the surface. As magma rises to the surface and cools, it loses some of its heat energy, resulting in the lower temperature of lava.
