Answer:

These 5 principles can be better understood from the past events as well as from formation of the sedimentary rocks

Explanation:

Principle of original horizontal- the sedimentary rocks are found to be horizontal during the initial deposits phase. If tilted this is due to the subsequent geological event.

Principle of original lateral continuity- The sedimentary beds are originally laterally continuous into their environment of deposition. Faulting in the severe folding and also erosion may leads to the separation of the originally lateral continuous beds which in later becomes separate units.

Principle of cross cutting- The younger features can get cuts across the older features. That's why faults, erosion, volcanoes etc can be seen. The above mentioned are younger than those materials that is faulted intruded, or eroded.

Principle of inclusion- Inclusion itself means (a rock fragment another rock fragment) they must be older than the materials in.

Principle of uniformity- Those are the physical process that are been seen today, were also worked in the same way in the geologic past, thus modern methods helps us to understand the ancient events.

The layers that make up the upper mantle are the following.

The lithosphere and the asthenosphere.
The lithosphere and the asthenosphere are the layers that make up the upper mantle.
The rocky outer part of the Earth is called the lithosphere.
It is very rigid, solid, and it is not as hot as the other parts.
According to scientists, its thickness is about 90 to 100 kilometers from the surface of the earth.
The layer of the Earth that moves the lithospheric plates is called the asthenosphere.
Lithospheric plates are 60 miles long on average and are composed of continental crust.

We conclude that the lithosphere and the asthenosphere are the layers that make up the upper mantle. The new lithosphere is being created at oceanic ridges due to plate tectonics. Yes, planet Earth is getting larger constantly.

A student holds an egg outside of an open window and let's go. The window is 40 meters above the ground and the egg is falling u

melisa1 [442]

The distance traveled by the egg after 2 seconds is 19.6 m.

The given parameters:

Height of the window, h = 40 m

The distance traveled by the egg after 2 seconds is calculated as follows;

$h = v_0_y t + \frac{1}{2} gt^2\\\\$

where;

$v_0_y$ is the initial vertical velocity of the egg = 0
g is acceleration due to gravity = 9.8 m/s²
t is the time of motion, = 2 s

$h = 0 \ + \ \frac{1}{2} \times 9.8 \times (2)^2\\\\h = 19.6 \ m$

Thus, the distance traveled by the egg after 2 seconds is 19.6 m.

How can energy be traced as it is converted through different transformations?

Mumz [18]

Answer:

Energy transformations are processes that convert energy from one type (e.g., kinetic, gravitational potential, chemical energy) into another. Any type of energy use must involve some sort of energy transformation.

Mosses don't spread by dispersing seeds; they disperse tiny spores. The spores are so small that they will stay aloft and move w

AnnyKZ [126]

A) 0.3

The initial kinetic energy of the stream of spores is

$K_i = \frac{1}{2}mv^2$

where m is the mass of the spores and v = 3.6 m/s is their initial speed.

The final gravitational potential energy (at the point of maximum height) of the spores is

$U_f = mgh$

where g=9.8 m/s^2 is the acceleration due to gravity and h = 20 cm = 0.20 m is the maximum height.

Therefore, the fraction of kinetic energy converted to final potential energy is

$\frac{U_f}{K_i}=\frac{mgh}{\frac{1}{2}mv^2}=\frac{2gh}{v^2}=\frac{2(9.8 m/s^2)(0.20 m)}{(3.6 m/s)^2}=0.30$

So, about 30% of the initial kinetic energy is converted into potential energy.

B) It has been transformed into thermal energy of the spores and surrounding air

In fact, because of the presence of the air resistance during the motion of the spores, some of the mechanical energy of the spores is "wasted" and converted into thermal energy (heat) of the spores and the surrounding air. Without the air resistance, the mechanical energy would be conserved, and the final potential energy of the spore would be equal to the initial kinetic energy.
