Answer:
B. establish communes and promote labor-intensive agriculture
Cascades, Sierra Nevadas and Coast Range.
Answer:
Fossil B belongs to the same period as the trilobite.
Explanation:
The Law of Superposition states that the youngest rocks will always be found on top of older rocks. So as you dig deeper and deeper, the rocks you find will be older and older.
An illustration of the problem:
<em>----------------------------------------------------------------------------</em>
Fossil C: Two Semi-circles (<u>Top</u> Layer = <em>Youngest</em>)
-----------------------------------------------------------------------------
Fossil B: Rhombus with Diagnonal & <em>Trilobite</em> (<u>Middle</u> Layer)
------------------------------------------------------------------------------
Fossil A: Shaded Rhomboid (<u>Bottom</u> Layer = <em>Oldest</em>)
So, Fossil A is older than both B and C, or, B and C are both younger than A.
Fossil B is Younger than Fossil A, but older than Fossil C.
Fossil C is the youngest (because its on top).
Answer:
The Earth's atmosphere protects and sustains the planet's inhabitants by providing warmth and absorbing harmful solar rays. In addition to containing the oxygen and carbon dioxide, which living things need to survive, the atmosphere traps the sun's energy and wards off many of the dangers of space.
Even though the sun is much more larger and has stronger overall gravity than the moon, the moon is much closer to the earth so that is the reason why its gravitational gradient is stronger than that of the sun
