The correct answer is option A

The age of the rocks can be determined by the studying the faults that is always younger than the rocks it cuts through.

A fault is a crack or break caused in the rock. Any layer of the rock which is cut by the fault is older and the fault formed is younger.

There are many other ways which is used by the geologists to determine the age of the rock.

Option A, a fault is always younger than the rock it cuts through

Reason:

Basically there are three modes of determining the age of rock

1) In a sedimentary rock, the layer at the bottom is the oldest. It is called as law of super position

2) If a rock layers lies below an extrusion, then it is always older than the extrusion

3)a fault is always younger than the rock it cuts through

How do the Earth and Moon compare in terms of gravitational force?

Law Incorporation [45]

The Earth and Moon compare in terms of gravitational force as Earth's gravitational force is stronger than the Moon's.

Option A

Explanation:

According to universal law of gravity, the gravitational force is the attractive force between two objects separated by a distance. The magnitude of gravitational force is directly proportional to the product of masses of the objects and inversely proportional to the square of the distances between them.

In this case, the gravitational force acting on us due to Earth will be considered due to the mass of Earth as the mass of Earth is very large compared to our mass.

$F=\frac{GM}{R^{2} }$

So as the mass of the Earth is greater than the mass of the moon, so the gravitational force of Earth will be stronger than that of Moon.

Tanzania [10]

Answer:

Photosynthesis produces: glucose and $O_{2}$

...from $CO_{2}$ , energy (light) and $H_{2} O$

Respiration produces: energy (ATP), $CO_{2}, H_{2} O$

....from glucose and $O_{2}$

Explanation:

These end products, namely $O_{2}$ and glucose are then used in respiration...

Using energy in the form of solar energy, plants, phytoplankton, algae, and other microorganisms produce chemical energy via photosynthesis. This complex mechanism is central to these species.

They combine light energy from the sun, water, and carbon dioxide.

6 $CO_{2}$ + 6 $H_{2} O$ + (energy) → $C_{6} H_{12} O_{6}$ + 6 $O_{2}$

In the mechanism of cellular respiration, organisms extract energy from food. Sugars in the form of glucose are broken down into carbon dioxide and water during aerobic respiration in mitochondria to produce energy in the form of ATP (adenosine triphosphate).

<h3> $C_{6} H_{12} O_{6} + 6 O_{2} _{\to \$ $6CO_{2} + H_{2} O + energy (ATP)$ </h3>

The waste products, $CO_{2}$ and $H_{2} O$ , result from respiration, these are used as reactants in the photosynthetic process. In turn, its products are the reactants $O_{2}$ and $C_{6} H_{12} O_{6}$ in respiration.
