Rhyolite lavas . a) do not flow as far from the vent as basaltic lavas do b) are commonly found at oceanic hot spots c) are associated with volcanoes that almost never emit pyroclastic debris d) are commonly found on shield volcanoes.

a. do not flow as far from the vent as basaltic lavas do

Explanation:

Rhyolites are known as volcanic rocks. Volcanic rocks are rocks formed when magma(semi liquid) from the aesthenosphere solidifies on the surface of the earth crust. Rhyolites is regarded as an extrusive igneous rock since magma creeps or erupt to the surface of the earth forming lava. This lava later solidifies due to cooling.

Eruption of magma can produce this kind of rock. As magma erupt from volcanoes  it forms lava extending or spreading further not too far from the vent  . The lava that solidifies to form rhyolites are usually felsic.

Rhyolites lava is very viscous and flows very slowly due to the high silica contents. so because of it very slow movement it does not flow as far from the vent as less viscous basaltic lavas do.
