Answer:P and S waves do refract more abruptly when they pass through the major transition zones separating the layers of the Earth. ... The Moho shows up in seismic data as a distinct change in wave speed due to a change in density of the rock across this boundary.
Explanation:
1 passive 2 passive 3 active
Answer:
1. (x-4), (y+4)
2. In a transformation, the equation shows how much the original coordinate moves. In the equation above, the orignal coordinate would move to the left 4 places, and then up 4 places. This particular transformation is called a translation, as the shape is the same but only in a different spot.
3. Quadrilateral
4. The transformed polygon has the apostrophes after each letter, which means it is "prime" or not the original.
Explanation:
1. To write the equation, look at how the shape shifts. If the x coordinate moved 4 spaces to the left, then that means the equation is -4. Do the same for the y-coordinate, except keep in mind it is up and down instead of left or right.
2. The answer is self-explanatory.
3. A quadrilateral has 4 sides, and this can be applied to more specific shapes, such as a square or rectangle. Because this shape has no distinctive features, it is safest to call it a quadrilateral.
4. The answer is self-explanatory.
Answer:
All dinosaur fossils found by archeologists have been found a few centimeters below the iridium layer. So, the possibility of finding dinosaur fossils above the iridium layer is very slim.
Explanation:
Over 65 million years ago, dinosaurs roamed the earth but were canceled out as a result of an extraterrestrial impact on the earth's crust. Research proved that an asteroid brought the end of dinosaurs as the element iridium was found in the earth (since iridium is abundant in asteroids and not the earth's crust).
Records of fossils found have been between 13 to 60 centimeters below the iridium or the K-T boundary as it is called.
The answer should be 3a-6+14 = 3a+8.
