Answer:
Decrease.
Explanation:
Beavers need trees to make Dams, without Dams they'd be in danger because of other predators.
Answer:
Types of minerals change in heated<u><em> metamorphic </em></u>area rock. A record of biological time can be found in <u><em>sedimentary</em></u> area rock. Matter changes state from liquid to solid to form<u><em> igneous </em></u>area rock
Explanation:
Metamorphic rocks can be described as a type of rocks which arise by the phenomenon of metamorphism. Immense heat and pressure changes previous rocks (sedimentary, igneous or other metamorphic rocks) into metamorphic rocks.
Sedimentary rocks can be described as the type of rocks which are made by the deposition of minerals or organic particles and hence, help in evolutionary studies.
Igneous rocks can be described as the rocks which are made from lava or magma (hence changing state from liquid to solid).
When the two hydrogen atoms bond with the oxygen, they attach to the top of the molecule rather like Mickey Mouse ears. This molecular structure gives the water molecule polarity, or a lopsided electrical charge that attracts other atoms.
