List three steps that show how the sun provides energy for surface ocean currents

almond37 [142]

1. The sun’s thermal energy is exhibited from its surface traveling to the ocean floor in the day
2. As the heat energy is absorbed by the water, the currents move and rise as the ocean waters from the equator heads to the north phase of the planet. 
3. And then the waters from the polar areas heads to the south, while ascending and gushing it becomes heated by the sun.

The sun’s gravity also affects this body of water. Since it has a much more stronger gravitation pull than of earth though its far away hence, high tide and low tide tendencies.

Which of the following pairs of angles is not necessarily congruent

Alex

Answer:

E. $\angle 3$ and $\angle 5$ .

Explanation:

According to the figure, we have the following conclusions:

1) $\angle 1$ and $\angle 2$ are vertical opposite angles. ( $m \angle 1 = m \angle 2$ )

2) $\angle 2$ and $\angle 3$ are internal alternate angles. ( $m \angle 2 = m\angle 3$ )

3) $\angle 2$ and $\angle 4$ are corresponding angles. ( $m\angle 2 = m\angle 4$ )

4) $\angle 3$ and $\angle 4$ are vertical opposite angles. ( $m \angle 3 = m \angle 4$ )

But, $\angle 3$ and $\angle 5$ , since $m \angle 3 + m\angle 6 + m\angle 5 = 180^{\circ}$ , where $\angle 3$ is an acute angle and $\angle 6$ is a right angle, and $m \angle 4 + m \angle 5 = 90^{\circ}$ . Then,
