What type of basaltic feature is shown in this photograph?

Question

Quizplus · Accepted Answer

The photograph shows a surface texture that is smooth and ropey, which is characteristic of a pahoehoe lava flow. Pahoehoe lava flows have low viscosity and tend to form smooth, undulating surfaces as the lava cools and solidifies. Vesicles are gas bubbles that can be found in many types of volcanic rock. Volcanic bombs are large blobs of lava that are ejected from a volcano during an explosive eruption. Aa lava flows are characterized by a rough, blocky texture. Pyroclastic flows are fast-moving, superheated clouds of gas, ash, and rock fragments that are ejected during explosive volcanic eruptions, and they are not visible in the photograph.
