Which type of weathering involves the outer layers of rock peeling off due 1 to the rock expanding as it is heated and contracting as it cools?

Hydration

Exfoliation

Oxidation

Tree Root Action

Exfoliation

Explanation:

it peels of my teacher said it like an onion

Explanation:

Expansion of rock surface when heated by the Sun followed by contraction as the temperature falls can allegedly weaken bonds along grain boundaries and cause subsequent flaking off of rock fragments or dislodging of mineral grains. This is called insolation weathering.

the answer is lactic acid from anaerobic respiration. the acid in lactic acid is what creates sore and burning muscles. if you think about how acid burns that will give you a clue for questions like this.

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.
