Answer:
A. In undisturbed rock layers, the youngest rocks are on the bottom.
C. If one rock contains pieces of another, the rock containing the pieces is older than the pieces.
Explanation:
Relative dating is a form of dating rocks in which past events in geologic records are put their proper order without necessarily knowing their absolute ages. There are several principles that helps in relative dating of rocks. These principles are:
- Principle of superposition of strata
- Law of original horizontality
- Principle of lateral continuity
- Principle of inclusion
- Principle of fossil and fauna succession
Option A and C are false statements of principle of superpositon of strata and principle of inclusion.
A. In undisturbed rock layers, the youngest rocks are on the bottom.
According to the principle of superpositon of strata, "the oldest sedimentary rock layers are usually at the bottom and the youngest on the top".
C. If one rock contains pieces of another, the rock containing the pieces is older than the pieces.
This is a false statement of principle of inclusion, the principle states that "inclusions found in a sedimentary rock are older than the rocks that contains them". Inclusions are fragments or pieces of other rocks that are found in a rock. These inclusion are believed to be older than the rocks they are found in.
Answer would be A)rural west
Answer:
A. Higher standard of living for most people
The Green Revolution brought massive improvements in agriculture, which led to a great increase in food production that benefited most people around the world.
C. Pollution from fertilizers
The higher yields and output brought by the Green Revolution were facilitated by the extensive use of fertilizers in lands that are not as fertile/suitable for agriculture. This extensive use has also brought a new series of environmental problems.
D. Animal antibiotics and growth hormones
The Green Revolution was also manifested in the field of animal husbandry. In this field, antibiotics and growth hormones became commonplace for the same reason that fertilizers became commonplace in vegetable crops: increase output and productivity.
Answer: Trade winds
Explanation: Trade winds are those winds that have the flow from east to west in the tropical region.It is named as trade winds because it provides help to the traders which are in middle age. Its has about 5 to 6 meters per second as their average speed. They are winds that blow from the range of 0 to 30 degrees latitude.Thus,the correct option is the trade winds
The three factors that describe the movement of surface water in streams and rivers include agents of movements like air or wind, the bed slope, type of rocks, obstructions (i.e.crops or vegetation present), bed shape, and many other factors.
