Study the images of Earth’s crust and mantle in two different areas. Item A shows a Lava source going through the Mantle and Crust, rising above Sea level to surface labeled Hawaii. Item B shows the Mantle beginning level on the left and dipping down on the right; the Crust is level on the left, labeled Great Valley of California, with mountains on the right, labeled Sierra Nevada and Mount Whitney. How is Item A different from Item B? The crust under the ocean in Item A is thicker than the crust under the mountain in Item B. The mantle under the ocean in Item A is thinner than the mantle under the mountain in Item B. The crust in Item A is found partially below sea level as compared to the crust in Item B. The mantle in Item A is located far below a mountain as compared to the mantle in Item B.

Question 1 how do an ionic bond and a covalent bond differ? an ionic bond is an attraction between oppositely charged ions. a covalent bond is a sharing of electrons between atoms. a covalent bond is an attraction between oppositely charged ions. an ionic bond is a sharing of electrons between atoms. there is no difference. both an ionic bond and a covalent bond share electrons. there is no difference. both an ionic bond and a covalent bond are attractions between oppositely charged ions. question 2 what is the definition of a covalent bond? a bond between two positive ions a bond between two negative ions a bond between a positive and a negative ion a bond between two atoms question 3 what is a bond called that shares electrons between two neutral atoms? covalent bond ionic bond metallic bond polar bond question 4 water (h2o) is composed of the same elements as carbon monoxide (co). how do their properties compare? they have different properties because the arrangement of atoms is different. they have the same properties because they have the same atoms. they have different properties because they have different atoms. they have the same properties because they have the same arrangement of atoms. question 5 what is the definition of a chemical bond? a mutual attraction between the nuclei and electrons in two different atoms a mutual attraction between the nuclei and electrons in a single atom a mutual repulsion between the nuclei and electrons in two different atoms a mutual repulsion between the nuclei and electrons in a single atom
