The Earth's outermost layer, the crust, ranges in thickness from 6 to 70 kilometers. The oceanic crust is approximately 6 kilometers thick and the continental crust ranges from 20 to 70 kilometers.
The thickness of the outermost layer of Earth, known as the Earth's crust, varies depending upon its geographical position. The oceanic crust, which covers 55% of the Earth's surface, is about 6 kilometers thick and mainly composed of basalt. On the other hand, the continental crust, which covers 45% of the surface, ranges from 20 to 70 kilometers in thickness and predominantly consists of granitic rocks. So overall, the thickness of the Earth's crust ranges from 6 to 70 kilometers but accounts for only about 0.3% of the total mass of Earth.Learn more about Earth's outermost layer here:

The Andes mountain range of South America was formed at a ____.
a.
convergent boundary
c.
hot spot
b.
divergent boundary
d.
transform boundary
The correct answer is - a. convergent boundary.
The formation of the longest and highest mountain range in South America can be attributed to the collision of the Nazca tectonic plate and the South American tectonic plate. This two tectonic plates form a convergent boundary. That basically means that they are pushing against each other, and because of the incredible force and pressure, the land starts to lift up gradually in the surrounding are, thus forming a mountain range over time. In this case the result has been the formation of the Andes, that are stretching in a linear manner, in a roughly north-south direction, from the northern part of the continent to its southern part, in close proximity of the Pacific coastline.

When studying historical geology, which type of rock provides the most useful evidence for uncovering what occurred in the past?
metamorphic
sedimentary
igneous basalt
igneous granite
Answer:
From the point of view of historical geology, sedimentary rocks (option B) have characteristics that allow being the most useful to discover the events that occurred in the past.
Explanation:
Sedimentary rocks are the product of the lithification of the sediments of rocks originated by the weathering (meteorization) process, transported in the form of particles by environmental agents such as wind, rain, sea swell, among others.
The sediments that are deposited on the surface of the planet, over many years, go through a hardening process that turns them into rocks with heterogeneous material. The characteristics that make sedimentary rocks the ideal material for historical geology studies are:
The formation process, where particles from past eras are found.
Its structure more or less accurately indicates the environmental conditions of the time they originated.
They contain information about their formation mechanism.
Fossils, also evidence of past times, are found in sedimentary rocks.
In order for geologists to reconstruct events and characteristics of the past, sedimentary rocks provide valuable information that contributes to this work.

Final answer:
A measure of the amount of light given off by a star is its luminosity and apparent brightness. Luminosity refers to the total energy output of a star, whereas apparent brightness is how much of that energy reaches an observer on Earth, influenced by both the star's luminosity and its distance from Earth.
Explanation:
A measure of the amount of light given off by a star is its luminosity and apparent brightness. Luminosity is defined as the total amount of energy a star emits per unit time, usually measured in watts. It provides a scale to compare the energy output among different stars, with some stars having luminosities many times that of our sun. On the other hand, apparent brightness refers to the energy from the star that reaches an observer or a square meter of surface area on Earth each second, measured in watts per square meter (W/m²). This is influenced not only by a star's luminosity but also by its distance from Earth. Thus, when observing stars, astronomers distinguish between these two to understand both the star's true power output and how much of that power actually reaches us.
The determination of a star's apparent brightness, along with measurements of its distance from Earth, allows astronomers to calculate its luminosity. This calculation is vital for understanding not just how bright a star appears to us but its overall energy output in the vastness of space. The concept of magnitudes is often used to express apparent brightness, relating to how human vision interprets light intensity.

Why do farmers find it difficult to raise crops in the Northeast?
Answer:
The difficulty of raising crops in the Northeast is because there is a very harsh environment. First of all the soil is not very rich to allow the growth of crops as easy as in other regions. Also, water availability is more difficult. But the major factor is that the raising season is shorter and plants don't have enough time to grow.
Explanation:
The northeast is a territory that has been exploited for a very long time ago. Making it very ineffective because the soil lacks the nutrients that plants require to grow properly. Also, the farmers have to use many chemicals and additives to provide the soil the properties required to crop growth. Furthermore, climate conditions make cropping seasons shorter and more difficult for plants to survive. As well as access to water is more difficult and it is not as good as water in other zones.

How much does the atlantic ocean widen per year due to divergent boundaries
Answer:
About 2.5 centimeter per year
Explanation:
At the divergent boundaries the earth lithospheric plates moves away from each other . This occurrence might be in the continental plate/crust or oceanic plates/crust. The divergent boundary can be noticed in the middle of an ocean . This is the type of boundary occurring in the Atlantic ocean. The diverging rate at the Atlantic ocean is very slow at about 2.5 cm per year. The plates are moving away from each other thereby causing the up-welling of magma to create a new oceanic crust. The divergent boundary on the ocean floor like Atlantic ocean is usually found on the crest of the mid oceanic ridges. The boundary is also marked by shallow earthquakes and faults.
Why are there so many earthquakes in South America?
The western part of South America is a region that is geologically very active. This is due to the boundaries between the South American tectonic plate with the Nazca tectonic plate, and also with the Pacific tectonic plate. Since both, the Nazca and the Pacific plates are oceanic plates, they are heavier, and they subduct below the lighter plate of South America, thus enabling the pressure and temperature from the mantle to come out towards the surface on this boundary lines. This creates lots of earthquakes, as well as volcanic activity.
Due to its placement along tectonic plate boundaries as well as the presence of subduction zones, South America is prone to earthquakes.
The following are the causes of South America's high seismic activity:
1. Tectonic Plate Boundaries: South America's continent is positioned at the intersection of many tectonic plates. Along the Peru-Chile Trench, the Nazca Plate is subducting beneath the South American Plate, causing frequent and strong earthquakes in the region.
2. Subduction Zones: Subduction is the movement of one tectonic plate beneath another. The Andean subduction zone is formed in South America by the subduction of the Nazca Plate beneath the South American Plate. This zone runs over South America's western coast, creating strong seismic activity.
Despite the fact that South America is prone to earthquakes, the frequency and intensity of seismic activity vary across the continent.

Afghan migration to Pakistan and Iran is distinguished by
ethnic strife
permanent relocation by Afghans
little or no international aid
remittances sent to relatives in Afghanistan
longtime stays and repatriation
The correct answer is "longtime stays and repatriation."
Afghan migration to Pakistan and Iran is distinguished by longtime stays and repatriation.
Due to the many war conflict and violence in past decades and the poverty lived in most of the country, Afghans need to leave Afghanistan to try to look for better living conditions. They emigrate to Pakistan and Iran and are considered refugees. Since the years of the Soviet Union invasion of 1979, Afghanistan has lived in a constant period of armed confrontation, invasions, and terrorism.
