1. Describe the different layers or horizons of soil and identify the living components of each layer.
2. Describe the relationship between plant type and soil compatibility and explain the characteristics considered for plants to grow.
Answers
Answer:
1.Soils are named and classified based on their horizons. The soil profile has four distinct layers: 1) O horizon; 2) A horizon; 3) B horizon, or subsoil; and 4) C horizon, or soil base ((Figure)). The O horizon has freshly decomposing organic matter—humus—at its surface, with decomposed vegetation at its base.
2.Twenty elements are considered essential for plant growth because they are involved in metabolic functions required in the life cycle of the plant. Some, like carbon (C), oxygen (O), and hydrogen (H), can come from the air. Nitrogen (N) is made available to the plant from the air and soil. But most of the needed elements that are nutrients for plants come from the soil. They are not all equally important but all play a role in plant growth. Most needed are nitrogen (N), phosphorus (P), potassium (K), and sulphur (S). The others are calcium (Ca), iron (Fe), magnesium (Mg), manganese (Mn), zinc (Zn), copper (Cu), boron (B), molybdenum (Mo), chlorine (Cl), sodium (Na), cobalt (Co), nickel (Ni), and silicon (Si). They will be discussed in the next objective.

What ate the four types of general landforms how do geographers define them and what are the characteristics of each one?
Answers
Answer:
Mountains, hills, plateaus, and plains are the four major types of landforms. Minor landforms include buttes, canyons, valleys, and basins. Most geologists classify a mountain as a landform that rises at least 1,000 feet (300 meters) or more above its surrounding area. A hill is a landform that is higher than the surrounding land and has a visible summit; they're like mountains, only shorter. A plateau is a flat, elevated landform that rises sharply above the surrounding area on at least one side. A plain is a broad area of relatively flat land.

C.)pointing to the U.S. military presence on islamic soil
D.)pointing out that the united states does not buy enough Saudi oil
Answers
Answer:
Pointing to the US military presence on Islamic soil.
Explanation:
Al-Qaeda is a terrorist organization that reached its peak during the early 2000s, but since then has gradually been in decline. The leader of al-Qaeda was Osama bin Laden, a billionaire that had big influence and aspirations for the formation of one united Islamic Caliphate. This organization was a terrorist one, as it used violence and attacks on civilians and objects by having a political background.
While al-Qaeda has been on the scene before 2001, it wasn't that well known globally until this year, and what made it famous was the attack on the Twin Towers in New York, USA. It was a horrific attack in which two huge objects were leveled with the ground and a lot of innocent civilians lost their lives or got injured. Al-Qaeda stated that the reason for this act was because of the military presence of the US on Islamic soil, as well as their interference in the internal matters of the Islamic states and trying to control the region.

Some species of sharks are on the verge of extinction because of shark finning. Washington, California, Guam, and Hawaiʻi prohibit selling, trading, and possessing shark fins. Do you believe sharks should be protected? Should the United States and other countries support this ban? Why or why not?
Answers
Answer:
Sharks should be protected and that should be supported by all countries because the majority of the shark species are keystone species.
Explanation:
There are hunderds of different species of sharks throughout the oceans and seas. They are predators in the vast majority of cases and have a very important role in marine ecosystems. To put it simply, if the sharks go extinct, the marine ecosystems will crumble as we know them and there will be drastic changes in them.
Unfortunately, like many other marine animals, the sharks and their body parts tend to be very popular in a lot of countries around the world, and not having bans in a lot of countries means that they are heavily fished and many species have been driven to the verge of extinction. Considering their huge importance for the ecosystems and the consequences that will emerge with their elimination all countries, including the USA, should fully ban the fishing of sharks and using them as food or using their body parts, or if not a total ban then to be strictly regulated.

saying: "Respect others and others will
respect you."
Va) You need to respect your friends so that
they respect you.
(b) Respect yourself to be respected by
others.
(c) People do not respect you unless you
have high self-esteem.
(d) Self respect and respecting others are
not related
Answers
Answer:
a) You need to respect your friends so that they respect you.
Explanation:
The popular saying is related to the golden rule, which states that you should treat others in the same way you would want them to treat you. For example, if you want people to respect you, you have to respect them first.
Respecting yourself doesn't necessarily mean others will respect you. This makes choice b incorrect.
The saying doesn't talk about self-esteem, thus making choice c incorrect.
The saying doesn't show the relationship between "self-respect" and "respecting others." This makes choice d incorrect.
There is a saying that states, "Weather tells you what to wear each day; climate tells you what to have in your closet." Why is this the case?

why does the oceanic crust sink beneath the continental crust at the subduction zone
Answers
Answer:
oceanic crust sinks because it is denser and has higher specific gravity than the more silicon aluminum enriched continental crust. What drives substitution is convection and conduction in outer core of earth, that heat , only a small part of which is due radioactive isotopes, has to make it's way to Earth's surface by both conduction and convection. Iron and nickel o have the highest specific gravities of the 10 most common elements in the Milky Way Galaxy. This is why oceanic crust sinks and is subducted continental crust has to have a lot more force applied before it inks, because it doesn't want to sink.
