Answer:

True

Explanation:

  • The data form the earth's magnetic fields that are locked inside the earth's surface below and is thus an understood form seafloor spreading and plate tectonics and occurs at the concepts of the plate tectonics and is thus a valid form the viewpoints form the formation of the earth.

Answer:

TRUE

Explanation:

The basaltic rocks that are erupted at the seafloor are comprised of magnetic property, where the iron minerals are oriented in the north/south direction. It has been observed that the earth's magnetic polarity alters every time it erupts. This played a key role in determining that the seafloor spreading is taking place and which further provided as key evidence for the proving of the plate tectonic activity. The rocks formed at the mid-oceanic ridge are the youngest, and moving away from it, the age of the rocks increases.

Thus, the above-given statement is True.

Imagine that you are a member of a team of scientists who are drilling into a large crater approximately 200 km wide. The crater
yan [13]

Answer:

Explanation:

The team will obviously known that they have reach the crater because during impact the rock would have ungergone contact melting of the rock. However, the rock maybe composed of angular fragments in a matrix that may be similar or a different material underneath the crater. Suppose the scientist drilling further down the surface, there will be presence of little or no impact. But inside the crater there will be fragments of broken rocks. They will observe the shocked minerals and the drill will eventually located the undisturbed sequence of rocks at the crater floor.

In which of the following tectonic plate settings are volcanoes typically NOT found? a. Mid-ocean ridges b. Continental rifts c.
saul85 [17]

Answer:

Answer is D. Transform faults.

Explanation:

The transform fault is situation where the tectonic plates slide past one another. It can also be described as a conservative boundaries because it does lead to the creation or destruction of crust. But , the build up of pressure between two plates along the faults can produce earthquakes.

In this case, volcanoes settings can not be found in the transform faults because there is absence of volcanoes vent, which will allow the passage of the molten rock to the surface.

this fossil was found in a dry, mountainous area. What can you infer about how the area has changed over time?
WINSTONCH [101]

Fossils are the remains of plants and animals that have been preserved for millennia in stones under the Earth's surface. They contain the long chapters of the history of our Earth. Fossils tell us what the earth looked like many millions of years ago, what kind of animals and plants lived on its surface and how it was changing. Fossils show us a history of over a billion years old.


From the fossil from a dry, mountainous area we can conclude that the area was once underwater and over time the soil has risen as result of continental drift and uplift. So, a mountain was once the bottom of a prehistoric ocean or sea.
