Answer:
the principle of original horizontality and the principle of superposition
Explanation:
The <em>principle of horizontality</em> states that layers of sediment are originally deposited horizontally under the influence of gravity.
The <em>principle of superposition</em> states that the oldest layer layer is at the bottom and each layer above it is younger, with the youngest being at the top.
Unconformities help us find the age of different layers. An unconformity is a surface in which no new solid matter is deposited after a long geologic interval. <em>Angular unconformity </em>is a type of unconformity which different kinds of stratum were tilted or folded before deposition of younger layers of solid matter above the unconformity. Once the layers were folded and tilted, the older layers of the solid matter eroded, then the younger layers were deposited on the older layers. There <em>angular unconformity </em>is the contact between young and old layers of solid matter.
Therefore, these two principles therefore describe how the tilted layers are older than horizontal layers.
Answer:
(a) Kav Ne = Kav Kr = 7.29x10⁻²¹J
(b) v(rms) Ne= 659.6m/s and v(rms) Kr= 323.7m/s
Explanation:
(a) According to the kinetic theory of gases the average kinetic energy of the gases can be calculated by:
(1)
<em>where
: is the kinetic energy, k: Boltzmann constant = 1.38x10⁻²³J/K, and T: is the temperature </em>
<u>From equation (1), we can calculate the</u><u> average kinetic energies for the krypton and the neon:</u>
(b) The rms speeds of the gases can be calculated by:
<em>where m: is the mass of the gases and
: is the root mean square speed of the gases</em>
For the neon:
For the krypton:
