Astudent observes that in the middle of the day the sun is higher in the sky in summer than in winter. which of the following statements explains her observation? the orientation of the earth’s axis relative to the sun is different in summer than it is in winter. the orientation of the earth’s axis relative to the plane of the earth’s path around the sun is different in summer than it is in winter. the difference is not caused by changes in the orientation of the earth’s axis. it is caused by changes in the sun’s position in the solar system. the difference is not caused by changes in the orientation of the earth’s axis. it is caused by the days in summer is longer than days in winter.

It is caused by changes in the suns position in the solar system

It is caused by changes in the sun’s position in the solar system. It is because the days in winter are shorter which has a change a change in the position from the sun.

water is a polar molecule. a chemical bond is a force of attraction between atoms or ions. bonds form when atoms share or transfer valence electrons. atoms form chemical bonds to achieve a full outer energy level, which is the most stable arrangement of electrons. so, false

explanation:

in h2o molecule, two water molecules are bonded by a hydrogen bond but the bond between two h - o bonds within a water molecule are covalent. the greater the electronegativity difference, the more ionic the bond is. bonds that are partly ionic are called polar covalent bonds. nonpolar covalent bonds, with equal sharing of the bond electrons, arise when the electronegativities of the two atoms are equal.

one part of the electromagnetic spectrum that arrives on earth as solar radiation from the sun is the visible spectrum. wavelengths of the visible spectrum combine to form what we refer to as

answer - d) ultraviolet radiation.

violet /   380–450 nm / 668–789 thz

violet is number 1 in the chart of visible light.
