Answer: melting
Explanation: When water goes from its solid form (ice) back to its liquid form, this is known as MELTING. Condensation occurs when gas changes into liquid, not when ice changes into liquid.
Answer:
There are many things that can be read from ripple marks in sedimentary rocks. To start, a geologist looks at: the types (sizes, composition, shapes) of grains in the rock, the height of the “waves”, the distance between peaks (highs) and troughs (lows), whether the rock seems to be lying in its original position, and the internal shapes of the ripples (by looking at the edges of broken pieces). They also seek to determine the age of the rock and information about other rocks lying below and above the specific rock.
Answer:
commensalism
Explanation:
Commensalism is a type of ecological interaction between two species in which one speices benefits while other is unaffected. Commensalism also can be considered as a type of symbiosis-two species that live together. The interaction between human and its microbiota is beneficial for microbiota while it has no effects on humans.
Although, some bacteria (gut bacteria) can help in digestion. In this case, interaction with human is mutualism (both have benefits).
