Answer: Option (A) is the correct answer.
Explanation:
A process where due to natural forces like rain, wind, gravity etc rocks and soil are eroded is known as erosion.
Basically, the particles produced in weathering are carried away by erosion. It is a natural or we can say it is a geological process.
this process occurs on the surface of Earth and it does not affect Earth's mantle or core. Sun is the source of energy that due to which erosion occurs.
Thus, we can conclude that the removal of weathered products from rock is called erosion.
Answer:
Using the smallest coefficient the chemical equation is written as
3KOH(aq) + H3PO4(aq) → K3PO4(aq) + 3H2O(aq)
Explanation:
Neutralization reaction is a reaction in which acid and base reacts quantitatively to form salt and water.
Base = potassium hydroxide
acid = phosphoric acid.
KOH =potassium hydroxide
H3PO4 = Phosphoric acid
KOH(aq) + H3PO4(aq) → K3PO4(aq) + H2O(aq)
The number of atoms on both side (reactant and product) of the equation are not equal so, we need to balance it.
3KOH(aq) + H3PO4(aq) → K3PO4(aq) + 3H2O(aq)
The product are salt and water.
Salt = K3PO4
water = H2O
The equation is balanced on both sides .
The potassium atom is 3 on both sides , oxygen atom is 7 on both sides, hydrogen atom is 6 on both sides and phosphorus atom is 1 on both sides.

Sig Fig applies only to numbers that not zero, only except when the zero is after the the number.
For example:
0.0255 is three sigfigs
0.0050 is two sig figs
0.0005 is one sigfig
Answer:
The movement of water between these reservoirs, primarily driven by solar energy influx at the Earth's surface, is known as the hydrologic cycle

<span>The solubility of solutes is dependent on temperature. When a solid dissolves in a liquid, a change in the physical state of the solid analogous to melting takes place. Heat is required to break the bonds holding the molecules in the solid together. At the same time, heat is given off during the formation of new solute -- solvent bonds.</span>
