which condition causes changes in air pressure in the atmosphere?
building clouds
rapid air movement
condensation of water vapor
uneven heating of earth’s surface

Unevening heating of Earth's surface

Explanation:

since the Earth is made by land and water it absorbs the sunlight of the sun at different high levels. Pressure,wind includes that as well.

the answer would be knowledge about cars!

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.
