Both andesite and basalt are volcanic rocks. Basalt is denser and generally darker than andesite. It has a lower silica content and more iron and magnesium. It most often forms from pahoehoe or a'a lava flows and occasionally scoria cinders. Andesite forms from more slica-rich material and is often found in the form of ash, pumice, or volcanic bombs. It may also sometimes form block lava flows, which are more viscous that a'a or pahoehoe.

Which rock is most felsic out of rhyolite andesite and basalt?
Of these Rhyolite has the highest silica content.
What is the difference between basalt and obsidian?
obsidian is smooth but not basalt
What kind of rock andesite?
No. Andesite is classed as an 'intermediate' rock, being halfway in composition between a mafic and felsic rock. Mafic rocks are those that contain alot of ferromagnesian minerals (iron and magnesium) which give mafic rocks their dark colouring. Typical ferromagnesian minerals include olivine and pyroxene. Typical mafic rocks are basalt and gabbro. Felsic rocks, on the other hand, are low in magnesium and iron and are usually light in colour, such as granite and rhyolite. Andesite therefore typically contains a mixture of both felsic and mafic minerals and is classed as 'intermediate'.
What is a volcanic rock that contains pyroxene and has a fine grained texture?
Basalt or andesite could fit this description.
What is the difference in composition between a dacite and an andesite?
Dacite is more felsic in composition, containing more silica.

What is the igneous rock between granite and basalt?
Andesite is considered an intermediate rock between granite (felsic igneous rock) and basalt (mafic igneous rock), based on chemical composition.

What is andestic?
If u are referring to andesitic basalt, lava having a greater silica content than that of basalt. Andesite is a rock.
What is an andesite?
