Answer:

The answer is below

Explanation:

The question is not complete since no map is attached, but I would show you how to solve it.

When trying to determine the location of the epicenter of the earthquake, we need at least three different seismic stations. To find the epicenter, a method known as triangulation is used. This is done by drawing circle at each of the seismic stations with the radius of the circle equal to the distance from the station to the earthquake. The point of intersection of this three circles is the epicenter.

In this problem, a circle with a radius of 380 miles is drawn at Phoenix, 280 miles radius circle at Denver and a 880 miles radius circle at California. The point of intersection of the circle gives the epicenter. Note that the circles are drawn to scale.

Which conclusion is reasonable based on the continental drift hypothesis?

musickatia [10]

Based on the Continental drift hypothesis, it is believed that B. Continents may collide in the future.

<h3>Continental Drift Hypothesis</h3>

Posits that continents were once part of a super continent and then broke apart.
Posits that continents will keep moving until they collide again to form another super continent after which they will then break apart.

The hypothesis therefore posits that continents will collide at some point millions of years into the future with one such example being the Americas and Asia.

What are the 2 major sources of Earth's interior heat ?

sergey [27]

The heat that remains inside the Earth from its creation and radioactive decay are its main heat sources.

The deep earth receives heat from three main sources: (1) heat left over from the planet's formation and accretion, (2) frictional heating brought on by denser core material sinking to the planet's centre, and (3) heat from radioactive element decay.

The energy produced when unstable atoms decay is known as radioactivity, and it is a substantial contributor to the Earth's heat. The main source are the radioactive isotopes of uranium-235 (235U), uranium-238 (238U), potassium-40 (40K), and thorium-232 (232Th) in the Earth's mantle.

It is impossible to determine the "absolute" ages of sedimentary rocks because none of the grains in these rocks contain radioac

algol [13]

Answer:

False

Explanation:

The given statement is false,the Aging of sedimentary rocks can be easily done with direct dating of the Volcanic Ash layers. Moreover, sedimentary are layered the older layers are at the bottom and the younger layer are at the top. Although sedimentary rocks do not contain radio active element but their absolute age can be determine by direct dating of the Volcanic Ash layers.

The mineral fluorite is commonly sold in mineral shops as octahedral (8-sided) objects. This shape originates from ________.

valentina_108 [34]

Answer:

d) cutting a larger crystal along four perfect cleavage planes, forming a cleavage fragment.

Explanation:

Fluorite Octahedron crystals are formed narutally, but it's not common, they can be found more commonly as cubes, the majority of fluorite octahedron are formed when miners cit them along its natural cleave lines. 

I hope you find this information useful and interesting! Good luck!
