Question

answer questions about rocks and the rock cycle question 13 of 15 which characteristic is common to extrusive igneous rocks? a crystals b fossils c glassy surface d ribbonlike layers

Explanation:

Extrusive igneous rocks form when magma erupts onto the Earth's surface and cools quickly. This rapid - cooling often results in a glassy texture as there is not enough time for large crystals to form. Fossils are found in sedimentary rocks, ribbon - like layers are characteristic of metamorphic rocks, and large well - formed crystals are typical of intrusive igneous rocks which cool slowly beneath the surface.

Answer:

C. Glassy surface
