Compressional or P (for primary)
, Transverse or S (for secondary)
, Love, and Rayleigh. Primary waves push and pull the ground in the direction the wave is traveling. Secondary waves travel in the same direction, but they shake the ground back and forth perpendicular to the direction the wave is traveling. Love waves move back and forth horizontally. Rayleigh waves cause both vertical and horizontal ground motion.
The image shows the Convergent plate boundary.
<u>Explanation:
</u>
Convergent boundaries occur wherever the Earth’s tectonic plates move or collide toward each other.
As the plates converge, the denser, thinner tectonic plate sub-ducts or dives beneath the lighter, thicker, more buoyant tectonic plate.
As shown in the picture, the plates are composed of rigid lithosphere consisting of the crust of the earth and the uppermost mantle. Movement of the plates is driven by convection in the asthenosphere and lower mantle, which are softer and warmer than the lithosphere and can flow on geologic timescales. Convection is fuelled by heat generated from radioactive decay of elements in the Earth.
Answer:
Explanation:
x to the 2nd power plus 3x-4
x to the 2nd power minus 2x-8
1. The dividing out method my seem like the thing to do but really you to to combine like terms on the top and the bottom so the top an the bottom should become 3x to the 2nd power plus (-4) over 2x to the 2nd power minus (-8) since you can only divide 3x to the 2nd power and 2x to the 2nd power your answer would become 3-4 over 2-8 because both x to the 2nd power cancelled each other out now minus the top and the bottom and the answer would be -1 over -6
2. for example (4)(6) over 4 plus 6 it would be hard to divide this because you the top and the bottom equations have not been solved yet, but when you do solve them your answer would be 24 over 10 but you cant divide these evenly and when you do try to divide them you would get a decimal or 2.4 also your answer word be an improper fraction 24/10 which could change into 2 4/10nso i don't think is would be easy to divide in order not to make this mistake always make sure both the top and bottom equations are solved and make sure you can divide them
3.a one thing i always remember is the equation solved yet i so can i divide
3.b What is the dividing out method can it be used for the following equation (3+4x) to the 2nd power over (4-2x) to the 2nd power.
14.6 million square miles is the area surface of the moon
the moon is 80 times less than earth
