On Earth's surface, less direct and less intense solar radiation are received by the<em> poles.</em>
Answer: Option 2
Explanation:
Various parts of Earth's surface get different measures of sunlight. The part which is closer to the sun receives more radiation than the part which is far away.
The Sun's beams strike Earth's surface most <em>directly</em> at the<em> Equator </em>as it is near to the sun when compared to the<em> poles</em> in which it strikes the surface at an <em>inclination</em>.
Enzymes speed up chemical reactions by lowering the activation energy.
The gradient is calculated by dividing the change in field value by the distance. You would calculate the difference between the isolines that your line goes to and from. The using an index card, use the little key at the bottom that tells you how much distance each tick mark is on the key and copy it to your index card by putting the index card under the key and drawing a line straight down from the key to the index card. then see the difference between the lines in the distance which is probably either meter, kilometers or miles. Then divide the difference between the difference from the isolines by the actual distance.
A, is the correct answer.
The core is the densest because it is packed with SO much pressure that makes the molecules of nickel and iron(Elements of the core) immovable.
