Buildings can affect the surface albedo.
The surface is the outermost or uppermost layer of a physical item or area. it is the element or place of the object which could first be perceived by an observer through the usage of the senses of sight and contact and is the component with which other materials first engage.
A surface is the outermost layer of any physical object. it is the part of the object that may be perceived by an observer using their experience of sight and touch and is the portion with which surrounding substances first engage.

Nonpoint source pollution is pollution that affects bodies of water, so remembering this can help in the future with this type of question. Some examples of nonpoint source pollution are; Excess fertilizers and herbicides, oil and toxic chemical runoff, as well as sediment from eroding stream banks. I hope this helps :)
The formula (ma = F - Fg) is used to determine the net upward force acting on a body.
<h3>
What is net upward force acting on a body?</h3>
The net upward force acting on a body is the resultant or sum of all the upward forces acting on a body at a given time.
ma = F - Fg
where;
- F is the applied force
- Fg is the force of gravity
- ma is the resultant force
Thus, the formula (ma = F - Fg) is used to determine the net upward force acting on a body.
