Answer:
4. Glassy
5.phaneritic
6. Porphyritic
7. Alphanitic
Explanation:
Glassy or vitreous textures occur during some volcanic eruptions when the lava is quenched so rapidly that crystallization cannot occur. The result is a natural amorphous glass with few or no crystals. Examples include obsidian
Examples of aphanitic igneous rock include basalt, andesite and rhyolite.

Porphyritic textures develop when conditions during cooling of a magma change relatively quickly
