In the video, you learned about the evolution of cinder cones and basaltic lava flows. these features are formed by volcanic eruptions when magma is erupted at the surface of the earth. the photo in part a shows red hill, located in central new mexico. this site shows a distinct red cinder cone and adjacent lava flow. the basaltic lava flow has been broken up by processes of weathering and erosion.

Lava flow : Basaltic material is more common, formed by effusive eruption. Cinder cone : pyroclastic material is more common, explosive eruptionsBoth features : Pāhoehoe is common, extrusive igneous rocks.

Explanation:

A lava flow is a geothermal energy that is thrown out of the earth in the form of the lavas or magma at the planetary crust or the eruption so the hot temperatures of 700 to 1200 ° C. The lava is composed of the silicate, feldspar and the olivine and the mica and the quartz, etc.  A pahoehoe lava is a smooth and unbroken a lava type and has a billowy, undulating, or ropy surface and thus has a low viscosity. while a cinder cone is a vent on a volcano that id formed by the ash and the tephra.
