The convection currents are formed due to heating of molecules.

When the liquid molecules are heated, the liquid becomes larger in size and lighter in weight. The heated molecules take up more space and rise to the top, while the cooler molecules comes to the bottom and takes the place. This cycle is known as the convection current.

Convection currents are the result of differential heating. Lighter which is less dense and warm material goes upward while on the other hand, heavier which is more dense and cool material sinks. This movement creates circulation patterns known as convection currents in the atmosphere.

2-1. Point A is at elevation 2690 feet and is located 520 feet due north of point B which is at elevation 2220 feet. Point C is
meriva

Answer:

In the given topography, point A is the northern side at a height of 2690 feet. B is at a height of 2220 feet and location C has a height of 2340 feet. A and B are separated by a horizontal distance of 520 feet, B and C are separated by a horizontal distance of 250 feet and C is located at N35°E of point B.

From the above data, we can demarcate the topography of the area. The area is inclined towards the southern side as when we move from point A to C and C to A the elevation gradually decreases.

Thus, <u>the exposed rock unit in that area dips towards the South and the strike direction of this rock is the East-west direction.</u>

Dip is defined as the angle made by a rock bed with respect to a horizontal line and strike refers to the direction of the line that is formed due to the intersection between a rock surface and a horizontal plane.

Dip and strike always perpendicular to one another.
