You are an archeologist trying to determine the type of a volcano that erupted thousands of years ago. all you have are a few lava samples from the volcano's remains. you test your lava samples and determine that the magma that they formed from must have had a low viscosity but a high gas content. you also determine that some of the rock is basalt. what kind of volcano have you discovered? describe in detail the formation of a cinder-cone volcano.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
