What is it called when lava cools and hardens? Sometimes magma flows upward and is forced out onto the earth's surface during a volcanic eruption. Magma that reaches the surface of the earth is called lava. When it cools and hardens, it too forms igneous rock. Igneous rock that is formed on the earth's surface is described as extrusive.n:

The answer is b) raccoon!
only 10% of energy is passed to organism from the food.
so the raccoon, which is the highest in the food chain, will have the lowest amount of energy.
hope this helps!!
Answer:
Azurite and Magnesite react with hydrochloric acid.
Explanation:
These 2 rocks contain the carbonate mineral calcite dolomite. Carbonate minerals are unstable in contact with hydrochloric acid. When acid begins to effervesce (fizz) on a specimen, a reaction takes place and bubbles of carbon dioxide evolve, thus indicating the presence of minerals like calcite dolomite.
Hope my answer is correct and helpful :)
Grouse species have evolved living in environments with little vertical structure and in areas with minimum human activity (from roads and cultivation to other more complex infrastructure). In the recent decades, there has been a significant increase in wind energy development in diverse areas and ecosystems. This development involves construction and placement of tall man-made structures, such as wind turbines and other infrastructure in habitats with high wind capacity. These habitats are often occupied by grouse species. This coexistence could severely endanger the species survivorship and reproductive ability. It is very important to study grouse habitat selection and demography, so that appropriate regulatory guidelines can be applied to wind energy development.
