B The use of man-made satellites to take pictures of Earth
from space presents a privacy concerns to all humans.
C The Earth's consistent and circular orbit around the sun
keeps the length of Earth days regular.
OD Man-made satellites pose a serious threat to the
environment that natural objects in space do not
O E A satellite is in orbit as long as it is making a recurring
elliptical path around another object.
OF The shapes of the paths that satellites take around an
object allow them to stay in motion.

Answer:

Principal characteristics of a slate are:

It's a Metamorphic rock

As e metamorphic rock it is Foliated

It's origin is Regional metamorphism

Is a fine-grain rock, for that reason it has non-visible minerals

A slate is composed by principally by clay and Micas.

Explanation:

Slate rocks are fine-grain metamorphic rocks which original rock use to be a shale or a vocanic rock. It is foliated, becase of compression stress produced by regional metamorphism, it means, orogenic metamorphism common in compresive plate boundaries. The foliation are planes perpendicular to the stress direction. It has non visible minerals because of the size of it's original components; usually it comes from shales, sedementary rock with clay minerals that after metamorphism sometimes become micas.

Answer: Erosion can be harmful to a person's property, causing a negative effect since the person must have paid for the land and the risk of injury if it forms a manhole.

Answer:

Tectonic plates and Continental drift

Explanation:

   We know that those who perform the movements of the crust are the tectonic plates, which are made not only by the continents, but also by the ocean floor. These plates move slowly over the mantle, moving away or approaching.

   The lithosphere or earth's crust is the outermost part, above the mantle, the more viscous part that is overheated and causes the crust to move.

   These movements are proven by techniques and studies and the use of satellites that with the aid of laser beam are able to identify and measure the displacement of tectonic plates and the movement of continents.

Answer:

dunno, january?

Explanation:

B)

Answer:

The rocks are comprised of cracks and fractures in between the sediments and mineral grains that have the capacity to store fluid in them. This fluid is generally the water that contains various types of dissolved ions. These fluids in the rocks are very much important because the chemical reactions that take place include the change in mineral from one type to another new type. This can highly increase the amount of dissolved ions that are dissolved and transported by the water. This alteration of rock that occurs chemically due to these fluid refers to the process which is commonly known as the metasomatism. Whereas, the rock alters mineralogically due to the increasing temperature and pressure condition, that changes the grade of rocks.

This is how metamorphism alters the rock chemically in comparison to mineralogically.

Answer:

The Incas developed the land of present-day Chile, Argentina, Ecuador, Peru, and Bolivia.

Explanation:

The Americas were home to numerous civilizations that prospered before the Europeans came. Some of them had small territories, some medium-sized, and some very large. From what is know so far, the empire that expanded over the largest territory was the Inca empire.

The Incas initially formed their empire on the high Andes. As they were gaining power, they gradually started to conquer new territories, so from the Peruvian Andes, they managed to expand to the territories of present-day Ecuador, Bolivia, Argentina, and Chile. The empire, at its peak, occupied both highland and coastal lowland areas, and it was very well developed and connected with excellent road systems.
