Answer:
Io, Europa, Ganymede, and Callisto.
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.
Aphanitic rocks in contrast to phaneritic rocks, typically form from lava which crystallize rapidly on or near Earth's surface.
Porphyritic textures develop when conditions during cooling of a magma change relatively quickly
Explanation:
Answer: The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.
