Answer: Resistance

Explanation:

The tendency of a material to oppose flow of charges through it is known as resistance. It is an opposing force that acts against the electric current. It depends on the resistivity of the material, its length and diameter. It also depends on the temperature. With increase in temperature, resistance increases.

$R = \frac{\rho l}{A}$

It is measured in Ohms (Ω)

At constant voltage,

$I \propto \frac{1}{R}$

Thus, more resistance leads to low current value.

How does air pressure change with altitude?

charle [14.2K]

Air pressure changes with altitude because of issues related to gravity. Molecules have more weight the closer they are to the Earth and more of them move to lower elevations as a result; this causes increased pressure because there are more molecules in number and proximity. Conversely, air at higher elevations has less weight, but also forces pressure on those layers below it, resulting in the molecules closer to the Earth supporting more weight, increasing the pressure

Describe the difference between a soil horizon and a soil proﬁle

mario62 [17]

Soil profile includes all the sections/ horizons of the vertical soil depth from top to bottom including the transitions from one horizon to another. A soil horizon is a distinct layer/section of soil with more or less the same texture. Therefore, a soil profile is made of soil horizons.
