Answer:
global warming is a hoax it is proven that the number we tampered with to make it look like we all were going to die.
Explanation:
Answer:
1 A. Body waves are described as compressional or shear
2 A. S-waves and C. P-waves
3 A R-waves and C. L-waves
Explanation:
Body waves are usually compressional or shear waves. The compressional wave, there is a push and pull in the direction of the propagating waves resulting in compression. shear waves involves transverse motion perpendicular to the direction of propagation.
S-waves are known as shear waves and p-waves are known as primary waves or compressional waves. Both are Body waves.
L-waves are called love waves and R-waves are called Rayleigh waves. Both are types of surface waves which are far more destructive than body waves.
Answer:
b less dense and thicker under the continents than under the oceans
Explanation:
- <em>Oceanic crust </em>is found under the ocean, it's about 6 kilometers thick and is destroyed in subduction zones just like the continental crust. It's composed of several layers and it differs from continental crust because it's thinner, denser, younger and with a different chemical composition (olivine, pyroxene, and amphibole).
- <em>Continental crust</em> is thicker (100 kilometers) and less dense than oceanic crust, it resists subduction and its age is 30 times the average of the ocean's age.
Considering this information we can conclude that the correct asnwer is: b less dense and thicker under the continents than under the oceans.
I hope you find this information useful and interesting! Good luck!

If it's cold in the winter then it's la niña
Answer:
Layer B is older than intrusion A
Intrusion A is older than layers C, D, and E.
Layer B is older than layers C, D, and E.
Explanation:
The laws of biostratigraphy can be applied to this lithological section in order to ascertain the relative ages of the beds.
Some of these laws that are applicable to this problem are:
- Principle of superposition of strata : the oldest layer is always at the bottom of sequence while the youngest is on top in an undisturbed rock sequence.
- Law of cross-cutting: when faults and fractures cuts through a rock sequence, they are younger than the rock they cross through.
- Law of intrusions: Intrusions are younger than the rock layers they cut through
The geologic history of the beds here can be interpreted as thus:
- Lithology B was first deposited
- Then an intrusion A occurred and terminated at B
- Layers C, D and E were then deposited.
The oldest layer here is B followed by the intrusion A and successful deposition of C, D and E in that order.
