Answer:

after

Explanation:

The rock inclusions are older than the rock that is surrounding them. In this case, we have a rock inclusion that is dated to 56 Ma. It is an inclusion in basalt. This means that the lava flow, as it was moving in that area managed to get the rock inclusion, and as the lava started to cool off, it consolidated and trapped the rock inclusion in it for time to come. This makes up for a very interesting appearance of the rocks, as there is the basis, being all from the same type of mineral, and then inside of the uniform rock mass, there is a totally different smaller piece of rock sticking out.

Answer:Unlike catastrophism, _______ states that mountains formed slowly over time.

William Smith was working as a surveyor in the late eighteenth century. He noticed that certain fossils were found in certain layers of sedimentary or igneous rock, that the same order of strata could be found in areas that were far apart, and these strata contained similar _______.

Isotopic dating relies on a process called _______, where heavier radioisotopes transform into lighter elements.

The Permian Period lasted from 299 Ma to 251 Ma. This means that the Permian Period lasted _______ years.

A rock inclusion in a basalt lava flow is dated at 56 Ma. This means the lava flow must have occurred _______ 56 Ma.

Respond to the following based on your reading.

You are trying to assign a date to a layer of tephra. While examining the tephra, you notice that it contains several shale inclusions. If you determine that the dates of the shale inclusions range from 910 ka to 1.3 Ma. What can you say about the age of the tephra layer?

Explanation:answer:

1.Uniformitarianism

2.fossils

3.radioactive decay

4.48 million

5.after

6.The youngest age of the shale is 910 ka. According to the principle of inclusions, the shale formed before the tephra, so the tephra must be younger than 910 ka.

What climate will countries from the northern and southern hemispheres experience from having the least direct sunlight?(1 point
earnstyle [38]

Winter is the phase of year when countries in the northern and southern hemispheres, respectively, see the least amount of direct sunlight.

December, January, and February in the Northern Hemisphere and June, July, and August in the Southern Hemisphere are the months when a portion of the Earth experiences the least amount of daylight. The Earth's 23.5° axial tilt as it orbits the sun causes solitons and varying solar declinations. This indicates that, during the year, one of the hemispheres is tilted toward the sun and receives the most intense solar rays, while the other receives the least amount of sunlight.

Which statement best describes the difference between earthquake body waves and surface waves?
wel

Answer:

Surface waves have a longer duration and higher amplitude than body waves.

Explanation:

The stark difference between an earthquake body and surface waves is such that they have longer duration and a higher amplitude compared to body waves.

There are two categories of seismic waves that usually accompanies an earthquake:

  • body waves are faster and perpetuate in the subsurface. They reach the seismic station first and are discovered faster.
  • surface waves arrives later and they cause the damage produced by most earthquake waves. They perpetuate on the surface.
  • surface waves are the love and Rayleigh waves
  • body waves are the primary and secondary waves.

Lucinda has 9 ounces of flour. A batch of cupcakes requires 1/3 ounce of flour. A batch of muffins requires 1/4 ounce of flour.
NeX [460]

Answer:

9 more muffins

Explanation:

Lucinda has 9 ounces of flour.

To make a cupcake she requires 1/3 ounce of flour, therefore the number of cupcakes she can make from 9 ounces of flour can be given by:

(1/3)x = 9 where x is the number of cupcakes.

Therefore, x = 9 × 3 = 27 cupcakes

To make a muffin she requires 1/4 ounce of flour, therefore the number of muffins she can make from 9 ounces of flour can be given by:

(1/4)y = 9 where y is the number of muffins.

Therefore, y = 9 × 4 = 36 muffins

The number of more muffins she can make more than cupcakes from her flour = 36 - 27 = 9 more muffins
