Question

what rock is this?shalegneissbasaltgranitemarbleconglomerate

Explanation:

Basalt is an igneous rock that is typically dark - colored (often gray to black). It has a fine - grained texture. One of the characteristic features of basalt is the presence of vesicles (small holes). These vesicles form when gas bubbles are trapped during the rapid cooling of lava. Shale is a sedimentary rock with a fine, layered texture. Gneiss is a metamorphic rock with a banded appearance. Granite is an igneous rock with a coarse - grained texture (visible minerals). Marble is a metamorphic rock (usually formed from limestone) and is often more crystalline and less vesicular. Conglomerate is a sedimentary rock composed of rounded fragments. The rock in the image has the vesicular texture which is a key feature of basalt.
