Which type of magma is most explosive form of magma?

andesitic

Which three factors affect the formation of magma?

What three factors affect the formation of magma? Pressure, water, and temperature.

What are the factors that affect the melting of magma?

The factors that mainly affect in the formation of magma can be summarized into three: Temperature, Pressure and composition. Temperature plays a role in the formation of the melts in the magma. Generally magma has a temperature range from 700-1300 degrees Celsius.

What are two ways that mantle rock can melt without an increase in temperature?

Mantle rock can melt without an increase in temperature if there is a decrease in pressure exerted by overlaying rock layers. This is called decompression melting. Rocks can also melt in the mantle due to dehydration. A subducting slab carries with it water as it is pulled into the mantle.

What kind of rocks does magma help form?

Igneous rocks form when magma (molten rock) cools and crystallizes, either at volcanoes on the surface of the Earth or while the melted rock is still inside the crust. All magma develops underground, in the lower crust or upper mantle, because of the intense heat there.

Can you use vinegar to clean rocks?

If the stone is acid safe, soak it in vinegar for a couple of days to dissolve carbonate deposits. If the stone has rust deposits and is acid safe, you may be able to remove them with something like CLR Rust Stain remover. If you need to go this route, skip the vinegar step, as this will also clean carbonate deposits.

What rock fizzes in acid?

Limestone

What does it mean when a rock reacts to acid?

To most geologists, the term “acid test” means placing a drop of dilute (5% to 10%) hydrochloric acid on a rock or mineral and watching for bubbles of carbon dioxide gas to be released. The bubbles signal the presence of carbonate minerals such as calcite, dolomite, or one of the minerals listed in Table 1.
