1. the earth spining on its axis.
a.92.96 million mi
b.<span>When the sun's rays strike Earth's surface near the equator, the incoming solar radiation is more direct (nearly perpendicular or closer to a 90˚ angle). Therefore, the solar radiation is concentrated over a smaller surface area, causing warmer temperatures.
c.</span><span>The moon's gravitational pull on the Earth is the main cause of the rise and fall of ocean tides. The moon's gravitational pull causes two bulges of water on the Earth's oceans—one where ocean waters face the moon and the pull is strongest and one where ocean waters face away from the moon and the pull is weakest.

Explanation:
When we find elements with high ionization energy in the upper right corner because the zeff experienced by the outer electron is high and electrons that are close to the nucleus.
The low Ionization energy elements are found in lower left where majority is of metals. The Zeff is low as the outer electrons are distance from the nucleus.
D. 2,3,4-trimethylpentane

Answer: Carbon Hydrogen and water
1:2:1
Explanation:
Carbohydrates are made of Carbon Hydrogen and water. Hence, they are represented by a general formula Cx(H2O)y.
Carbohydrates have carbon, hydrogen and oxygen in ratio 1:2:1, as is found in glucose (C6H12O6), Glycerose (C3H6O3), Ribose (C5H10O5).
Thus, in all sugars carbon, hydrogen and oxygen are found in ratio 1:2:1
