Answer:
C: Plates float on the liquid mantle located below the crust.
Explanation:
Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Scientists once thought that Earth’s plates just surfed on top of the mantle’s giant convection cells, but now scientists believe that plates help themselves move instead of just surfing along. Just like convection cells, plates have warmer, thinner parts that are more likely to rise, and colder, denser parts that are more likely to sink.

Answer:
Construct validity
Explanation:
A researcher wants to measure attitudes towards gun control by asking people whether they would be worried about traveling to areas where there are known to be a lot of illegal guns. Critics argue that the conceptualization does not really look as though it is related to attitudes about gun control, in other words, that it lacks <u>construct</u> validity.
Construct validity is the degree to which a research studies the data or measures it claims to be studying, that is, the degree the measures taken in a study is reflective of the goal or aim of the study. If a researcher takes measures that is not reflective of the aim of his study, that study could be said to lack construct validity.

preplanning is so important because it helps us to achieve our goals and to get success in our life...:)
Subsistence farming is not used anymore, only occasionally in certain parts of the world but in the 1800's it was used in the U.S. by people who only planted enough to get them by, and if they had the smallest portion left they traded it, typically for alcohol
