What is the definition of chemical weathering?

1 answer:

7 0

Chemical weathering refers to the erosion or total disintegration of rocks that are caused by chemical reactions and not by mechanical processes. Usually water and other liquid substances causes this to occur. Skyscrapers or buildings are prone to chemical weathering because they are constantly exposed to precipitation and other elements in the atmosphere. In rocks, when this process happens they tend to crumble and form smaller rock pieces. It is important to note that during this stage, the end product is a totally different substance than its original phase.

Which statement correctly compares mass and weight?

hram777 [196]

Answer:

D. Weight varies with location, but mass does not vary

Explanation:

Weight can be defined as the force acting on a body or an object as a result of gravity.

Mathematically, the weight of an object is given by the formula;

$Weight = mg$

Where;

m is the mass of the object.
g is the acceleration due to gravity.

Mass can be defined as a measure of the amount of matter an object or a body comprises of. The standard unit of measurement of the mass of an object or a body is kilograms.

Irrespective of the location of an object or a body at a given moment in time, the mass (amount of matter that they're made up of) is constant. This ultimately implies that, whether you're in the moon, space, earth or any other place, your mass remains the same (constant).

<em>Hence, the statement that correctly compares mass and weight is that, weight varies with location, but mass does not vary. This is simply because acceleration due to gravity changes with location i.e its value varies with the planets.</em>
