Which soil horizon is the least weathered horizon and contains rock that is starting to break down into soil
Answer:
The C horizon (Subsurface horizon).
Explanation:
The C horizon is a subsurface horizon which is the least weathered horizon; also known as the saprolite.
It is a zone of little or no humus accumulation or soil structure development. and is often composed of loose unconsolidated parent material from which the A and B horizons have formed.
A horizon is a mineral subsurface that is a zone of accumulation, the horizon of the Subsurface horizon.
What exactly is a subsurface horizon?A horizon is a mineral subsurface horizon that is a zone of accumulation. Clay, salts, and/or iron are common materials that accumulate. Minerals in the B horizon may be undergoing transformations, such as chemical changes to the structure of clay.
The C horizon is a subsurface horizon that is the least weathered; it is also known as the saprolite.
It is a zone with little or no humus accumulation or soil structure development. And is frequently made up of unconsolidated loose parent material from which the A and B horizons have formed.

The volcano Izalco in El Salvador is a small, steep-sided volcano. What conclusions can be drawn about the characteristics of the lava that formed this volcano?
Answer:
Izalco is likely a stratovolcano, given its steep slopes. The lava of a stratovolcano is high in silica content and is very viscous (thick). It thus cannot flow very far and often solidifies before reaching a long distance. The volcano continuously erupts and the solidified lava builds on the existing land, forming steep slopes.

5. If two vertical angles are represented by 2x + 40 and 5x + 25.
what is the value of ?
Answer:
Vertical angles must be equivalent to each other, so we can set this equation:
2x + 40 = 5x + 25
Solve
15 = 3x
x = 5
I will assume the question is asking for the angle, so we plug in x
5*(5) + 25 = 50

5. The point in Earth's interior where the energy release of an earthquake occurs is the:
A. Focus
B. Epicenter
C. Shadow zone
The point within the earth where the fault rupture starts is called the focus or hypocenter. This is the exact location within the earth were seismic waves are generated by sudden release of stored elastic energy.
The point in Earth's interior where the energy release of an earthquake occurs is the focus. The correct option is a.
What is an earthquake?An earthquake is the shaking of the surface of the Earth resulting from a sudden release of energy in the Earth's lithosphere that creates seismic waves.
Earthquakes can range in intensity, from those that are so weak that they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular period. The seismicity at a particular location on the Earth is the average rate of seismic energy release per unit volume. The word tremor is also used for non-earthquake seismic rumbling.
At the Earth's surface, earthquakes manifest themselves by shaking and displacing or disrupting the ground.

The U.S. Federal Reserve says problems with the supply chain are threatening to
lengthen the rise in prices of goods and services, which is known by what one-word
term?
Answer:
Inflation
Explanation:
A supply chain, in the most basic form, is the set of actions necessary by an organization by providing goods or services to customers.
A supply chain is a focus on the main processes necessary to turn raw materials or component components into completed products or services inside our company.
The correct word for the rise in the prices of goods and services is inflation.
This is the correct answer because inflation is measured as the rate at which prices go up over time. Inflation is usually defined as little more than a wide measure of price increases or a rise in the cost of living in a nation.
In economics, inflation is defined as a gradual increase in the price of goods and services in a given economy. When the overall price level rises, each unit of currency buys fewer products and services; as a conclusion, hyperinflation equals a loss of money's buying power.

If the distance between two places is 1000m and the height between them is 100 m, what is the gradient ?
The gradient between the two places is 0.1
Gradient (slope) is the ratio of change in vertical distance to change in horizontal distance. It is given by:
Gradient = vertical distance / horizontal distance
Given that the horizontal distance is 1000m and vertical distance (height) is 100 m, hence:
Gradient = vertical distance / horizontal distance
Gradient = 100 m / 1000 m
Gradient = 0.1
The gradient between the two places is 0.1

What can you find in the top layer of dense canopies in rainforests? The top layer has that grow to heights of meter(s) or more, which does not allow much sunlight to enter the canopy.
The canopy of a rainforest is defined as the top layer present 30 meters above the ground, which is made up of the overlapping leaves and branches of the trees.
The top layer of the canopies is known as the emergent layer that consists of a large number of trees and extends in height to all the plants.
What is the canopy of the rainforest?The long and enormous trees of the rainforest are extended to reach the direct sunlight. The canopy formed due to the overlapping of trees blocks out the sunlight available to the plants present beneath the canopy. 60-90% of the life forms are found in the canopy of the rainforests. It is one of the richest habitats and has biodiversity.The root system of the rainforests is shallow, and the bark is thin and smooth as the rainforests do not deal with cold weather.
Thus, the canopy reaches a height of more than 30 meters to achieve direct sunlight.
