Which statements concerning how geologists locate an earthquake’s epicenter are accurate? check all that apply. geologists use seismic waves to locate the center of an earthquake. the epicenter of an earthquake is located at the same place as the seismograph. geologists use data from two data stations to determine the location of an earthquake. geologists use data from three or more data stations to determine the location of the epicenter. a seismograph measures the difference between the arrivals of p waves and s waves.

Geologists use seismic waves to locate the center of an earthquake.

Geologists use data from three or more data stations to determine the location of the epicenter.

A seismograph measures the difference between the arrivals of P waves and S waves.

Explanation:

Seismic waves refer to the energy within the Earth due to sudden movement and explosions. Basically, they are the energy traveling within the Earth, and this energy cause movement, an excess of it will cause major movements, causing damage in the surface.

So, the epicenter of a earthquake is tracked using seismic waves, but this process more complex that we thought, because geologists need to track the epicenter using other data stations which offer real time information about seismic waves. Using all this data, geologist can find the epicenter faster and accurately.

There are different types of seismic waves, there's the Primary Waves or P-Waves, they are called primary because they are the first to perceive by the seismic station, they push and pull constantly, like a spring. Another type of seismic waves is The Secondary Wave or S-Waves, this is slower than the first one, this type of waves can moves mass of rocks up and down, constantly perpendicular to its direction. These two types are called body waves, and they are used by geologist to locate an earthquake.

Lastly, we have the surface waves, which only travel through the crust. In this category we have Love Waves which are the fastest, moving side to side. Also, we have the Rayleigh Waves, which are waves that roll the ground like ocean waves roll the water.

Therefore, based on these definitions, there are three correct answers, first, third and last one.

carbon is found in all living things. carbon atoms move constantly through

living organisms, the oceans, the atmosphere, and the earth’s crust in what is

known as the carbon cycle. the directions taken by carbon atoms through this

cycle are very complicated and can take millions of years to make a full circle.

all animals, from humans to the dinosaurs are part of the carbon cycle. when

animals eat food, they get carbon in the form of carbohydrates and proteins.

in animals, oxygen combines with food in the cells to produce energy for daily

activity and then gives off carbon. the carbon combines with oxygen to form

carbon dioxide (co2) and is released back into the atmosphere as a waste

product when animals breathe and exhale.

from 145-65 million years ago, earth was much

hotter than today and covered with dense,

tropical swamp forests. the trees and other

plants were immense and

provided an endless supply of

food for the giant animals that

roamed the land. somewhere in

the air above one of these

forests, a lone carbon atom has joined

up with two oxygen atoms to form a molecule of co2.

the co2 molecule was sucked into the tiny holes (stomata) on the leaf of a

fern plant and joined with sunlight, chlorophyll and water to make food and

energy in the plant’s cells through photosynthesis. the oxygen (o2) from the

co2 molecule was sent back into the atmosphere; the carbon atom (c) was

detached and used to make a molecule of sugar.

if that carbon atom had been eaten instead, a totally

different situation would have developed. let’s say

that a giant plant-eating dinosaur (herbivore) ate the

fern for breakfast, and swallowed the carbon in the

fern in the form of carbohydrates and proteins. in

the process of respiration, oxygen combined with

the carbohydrates and proteins in the dinosaur’s cells

to provide energy for its daily activity.
