This dinosaur lived long ago on Earth in a tropical climate. The dinosaurs were killed and became extinct because of a change in climate. That new climate was called an ice age. What type of fossil would we find that would support the theory that Earth experienced an ice age?

Geological, chemical, paleontological.

Explanation:

Geological evidence for ice ages comes in various forms, including rock scouring and scratching, glacial moraines, drumlins, valley cutting, and the deposition of till or tillites and glacial erratics.

Successive glaciations tend to distort and erase the geological evidence, making it difficult to interpret.

It took some time for the current theory to be worked out.

There have been at least four major ice ages in the Earth's past.

Paleontological by their bones, remains

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.

i believe your answer would be c.. : )
