This is about Earth's interior, select the correct word. Energy flows from the core toward the surface due to {pressure, temperature, density} differences. Energy moves through the lower mantle and asthenosphere as rock flows due to density differences. This type of energy transfer is called {conduction, convection, radiation}

1.) temperature

2.) conduction

Explanation:

Energy flows from the earth to the surface due to temperature differences. Energy moves through the lower mantle and asthenosphere as rock flows due to density differences. This type of energy transfer is called conduction.

you need to take a look at the periodic system in order to sort these elements into pairs that would most likely exhibit similar chemical properties. first, you need to find elements that are found in the same group (groups are vertical in the periodic system), and then to see whether they have the same valence number. if they meet these criteria, they will have similar properties.

the first pair: ne (neon) and kr (krypton), are noble gases found in group 8

the second pair: li (lithium) and k (potassium), found in group 1

the third pair: s (sulfur) and te (tellurium), found in group 6
