Folding and faulting are two examples of slow changes by which plate tectonics can shape Earth’s surface. Which of the following describes a difference between these two processes? A Folding is caused by circular movement of the plates around each other, while faulting causes pressure and heat to be reduced.
B Folding begins with the fracturing of the rock, while faulting takes place when high heat and pressure are exerted horizontally.
C Folding takes place when pressure and heat bend rock horizontally or vertically, while faulting begins with fracturing of the rock.
D Folding is caused by forces of the plates found close to the surface of Earth, while faulting occurs through continental collisions deep within Earth.

where is the following

explanation:

- calcium has greater affinity to bond with electron receptors than hydrogen does and hence, it has the ability to replace hydrogen in most of its compounds.

- lithium has 2 valence electrons in the product because it can make only 1 bond with hydrogen. beryllium has 4 valence electrons in the product because it can only make 2 bonds. it has fewer electrons than neon and can react with electron donors. each hydrogen has 2 valence electrons, the same as helium.

- the covalent bond formed between carbon and hydrogen is polar because carbon is more electronegative than hydrogen and it attracts the bonded electron pair closer to itself, thus giving hydrogen a partial positive charge.

- a hydrogen bond is a relatively weak bond that hydrogen atoms make with the electronegative atoms nitrogen, oxygen or fluorine.

so the best choice is a.) 2 calcium (ca) atoms
