C.subduction
D.trench formation
Answers
Answer:
The correct option is (B)mantle convection
Explanation:
Tectonic plates at the earth's surface move because of the intense heat in the Earth's core. this heat causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell and producing a movement called mantle convection which is the slow creeping motion of Earth's solid silicate.

Answers
Answer:
Nonmetals typically combine to form covalent compounds.
Explanation:
The octet rule states that the atoms of the elements bond each other in the attempt to complete their valence layer with eight electrons. That is to say, the atoms will tend to yield or share electrons to complete eight electrons in the valence layer.
In other words, the objective is to have the closest noble gas electronic configuration, thus having the last complete electron layer and acquiring stability.
The covalent bond is the chemical bond between atoms where electrons are shared, forming a molecule. Covalent bonds are established between non-metallic elements. These elements have many electrons at their outermost level (valence electrons) and tend to gain electrons in order to comply with the octet rule mentioned and be stable. The shared electron pair is common to the two atoms and holds them together.
Then, nonmetals typically combine to form covalent compounds.
Answer: ionic bonds can form between nonmetals and metals, while covalent bonds form when electrons are shared between two nonmetals.

Answer:
12500 J = 12.5 kJ
Explanation:
Kinetic energy is the energy possessed by a moving object solely due to its motion.
You can get the K.E. of an object using the equation,
K.E. = (1/2)mv²
So you get, for ball
K.E. = (1/2)×1000×5² = 12500 J = 12.5 kJ

For a pool ball, it's the work the ball does bending all the little cloth
fibers out of the way as it rolls along the table, and also the work it
does pushing air out of the way. These things rob a little bit of each
ball's kinetic energy, so that it eventually stops rolling.

Answers
Answer: An atom's ability to attract other electrons and form a chemical bond
Explanation:
The electronegativity of an atom tells of its power to attract electrons. Electronegativity values of elements ranges from 0 to 4.0, a high value means higher ability to attract electrons while a lower value means lower ability to attract electrons. Also, a wider difference in electronegativity between two atoms gives an ionic bond unlike a covalent bond with narrow difference.
Thus, nonmetals like chlorine higher electronegativities than metals like potassium.
