The lowest rock layer is a layer that must be rich in organic matter that was subjected to heat and pressure over time during the formation of oil and gas.
<h3>What is the lowest rock layer?</h3>
The lowest rock layer refers to the lowermost part of the Earth's mantle, which is a thin rock layer (approximately 250 km).
In the Earth, the layers of rocks are progressively deposited, thereby pressing them to the bottom to generate sedimentary rocks.
The lowest rock layers on the bottom must be rich in organic matter to form fossil fuels.

Classic mechanics and atomic physics
A horizontal force is applied to an object making it run with a constant velocity across a surface.
<u>Answer:</u>
Option (D)
Clockwise
<u>Explanation:</u>
Using Lenz's Law the current is induced in such a direction so that the magnetic field created due to the current induced opposes the increasing external magnetic field. For this case,when the field is increasing the magnetic flux increases and current is induced in clockwise direction (by lenz law as the induced field due to induced current has influence in opposite direction,thereby it reduces flux).
If the field is being decreasing,current would have been induced counter-clockwise so as to oppose the decreasing flux(as then the induced flux would be in same direction.)
