Q1- your feet get hot on a summer day as you walk on beach sand. which way is heat being transferred to your feet? a. radiation b. conduction c. convection q2- which of the following processes keeps earth's surfaces at a temperature to support life? a. insolation b. albedo c. greenhouse effect q3-what term is used to describe incoming solar radiation? a. insolation b. albedo c. convection d. radiation

The correct answer for Q1 is B. conduction

Conduction is transfer of heat from a region of higher temperature to one of lower temperature by the interaction of the two substance or particles. Here sand contain more heat than feet, so the flow of heat will be from sand to feet.

The correct answer for Q2 is C.Greenhouse Effect

The green house effect is process by which radiation from the earth's atmosphere warms the earth's surface. The strength of the greenhouse effect depends on the amount of greenhouse gas present in the atmosphere.

The correct answer for Q3 is A.Insolation

Insolation is amount of solar radiation reaching the earth's surface. We can measure insolation by measuring the amount of solar energy received per square centimeter per minute.

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

your parents i think this could be it
