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:
Density is one of the most factors that play a key role in plate tectonic activities. Some of the ways in which density is important in the field of plate tectonics are as follows-
- The convergent plate boundaries are responsible for the creation of a subduction zone, where the high-density lithospheric plate subducts below the less dense one. It is because the heavier plate is comprised of heavy minerals thereby forming heavier rocks as a result of which its density increases. Due to these differences in density, there occurs a subduction zone.
- The divergent plate boundary forms where two plates move away from one another. This type of plate motion is responsible for the eruption of magma on the seafloor. As the plates diverge, the lithosphere becomes eventually thin, and with more progressive spreading, the magma comes out to the seafloor. This is because the hot magma is less dense, and forms convection cells as they rise upward. This is how the density helps in the upwelling of magma at the mid-oceanic ridge in a divergent plate boundary.
- When there collide two plates of equal densities, then it gives rise to the formation of huge mountains, because neither of them is heavy to get sink. So it uplifts the crust, forming a sandwich-type pattern.
Answer:
The Moon doesn't make its own light, it just reflects the Sun's light as all the planets do. We see the Moon go through a changing cycle of phases each month due to its orbital motion around Earth and the changing geometry with which we view it.
The correct term for the lettered feature of the cross section showing the distribution of water in loose sediments are listed below:
- A _______ Soil Moisture
- B _______ Water table
- C _______ Zone of aeration
- D _______ Zone of saturation
<h3>Meaning of
distribution of water </h3>
Distribution of water can be defined as a set of processes and actions by which water is given to different sections of the soil.
Water distribution is very important as the need for water differs in each level.
In conclusion, The correct term for the lettered feature of the cross section showing the distribution of water in loose sediments are listed above.
