It isn't slimy. It is viscous when molten, proportionally to the silica content, but is not at all slimy even when solid. Lava-flow surfaces may become slimy with algae in certain situations - but that's a different matter!
Lava is viscous because of its physical properties and the strength of the bonds between the particles in the liquid.
yes
Continental plate.
An explosive eruption typically produces thick and sticky lava known as silica-rich or felsic lava. This type of lava has high viscosity and trapped gas bubbles, causing it to erupt violently. As the lava is very viscous, it can block and build pressure in the volcano, resulting in explosive eruptions.
== == Felsic lava has a higher silica content than mafic lava. Felsic lava is slower moving (high viscosity) than the less viscous mafic lava. Mafic lava is higher in dark minerals and higher in the elements iron and magnesium.
A mafic lava flow will move faster than a felsic lava flow due to its lower viscosity. However, felsic magma tends to erupt explosively, producing fast-moving pyroclastic flows instead of lava flows.
Felsic magma.
Felsic lava is a slower moving lava, with high silica content. Most felsic lava deposits as granite, granite, muscovite, and orthoclase.

Mafic lava is hotter than felsic lava and therefore flows faster.

Felsic magma.
The term felsic des derived from feldspar and silica, which are the primary components of felsic rock.
Paricutin erupted mafic lava.
felsic lava
the type of lava from mt vesuvius is felsic lava in a pyroclstic explosion.
Felsic magmas that are high in silica content and are highly viscous produce explosive eruptions.
