Describe the difference between atoms, molecules and compunds please help

Atoms are the thing that make up molecules and compounds. Molecules contain two or more atoms and are held together by covalent bonds, whereas compounds are held together by ionic bonds.

The atoms within a compound also must be different from eachother, whereas a molecule can consist of only one element.

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
