How do materials move within the earth.
statuscvo [17]

The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

<h3>How do materials move within the earth?</h3>

The Earth's thermal energy is the main cause of the movement of materials within the earth surface. The Large continent-size plates moves slowly about the Earth's surface, which is driven by the thermal energy. The Convection currents transfer hot, buoyant magma to the lithosphere's layer at plate boundaries and hot spots. Convection currents also transfer denser, cooler material from the crust to Earth's interior through the process of subduction.

So we can conclude that: The new materials from the center of the Earth rises, so the hardens and pushes older pieces of the Earth away from each other, which causes the movement of materials.

White a paragraph comparing the organices in a to the organs in your body.
Vlada [557]

Answer:

* Organelles are structures inside the cytoplasm of cells

* Organs are amde up of tissues composed of group of specialized cells that, has a particular role in the body

A geologist is studying two different rhyolite flows to determine if they were erupted at the same time.
ss7ja [257]
Q1. The answer is 1.

It can be calculated using the equation:

 (1/2)ⁿ = x

x - decimal amount remaining, 

n - a number of half-lives.


x = 50% = 50/100 = 0.5

n = ?

(1/2)ⁿ = 0.5

log((1/2)ⁿ) = log(0.5)

n * log(1/2) = log(0.5)

n * log(0.5) = log(0.5)

n = log(0.5)/log(0.5)

n = 1


Q10. The answer is 2.


It can be calculated using the equation:

 (1/2)ⁿ = x

x - decimal amount remaining, 

n - a number of half-lives.


Rhyolite #2 has 25% of the parent H remaining:

x = 25% = 25/100 = 0.25

n = ?

(1/2)ⁿ = 0.25

log((1/2)ⁿ) = log(0.25)

n * log(1/2) = log(0.25)

n * log(0.5) = log(0.25)

n = log(0.25)/log(0.5)

n = -0.602 / - 0.301

n = 2



Q3. The answer is 100 million years.


A number of half-lives (n) is a quotient of total time elapsed (t) and length of half-life (H):

n = t/H

n = 1

t = ?

H = 100 000 000 years


n = t/H

t = n * H

t = 1 * 100 000 000 years

t = 100 000 000 years<span>
