2) If the foliation on a rock is running north-south what direction is the tectonic pressure coming from?

Answers

Answer:

if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down)

Explanation:

The pressure is the second most principal factor that influences metamorphic rocks. It originates from the weight of the own materials, their densities, and the deepness.  

Litostatic pressure originates from the weight of materials in the interior of the crust.

Pressure generates alignment of materials (foliation and schistosity) and mineral rotation.

There are different types of metamorphism.

Dynamic metamorphism is the one where pressure is the principal factor. It generates by tectonic conditions, and it presents mainly in failure or fracture areas. It provokes trituration and recrystallization of minerals.

Classification of the metamorphic rocks according to their structure:

GranulationRecrystallizationMetasomatismMassiveFoliation

Foliation refers to dynamic metamorphism, where pressures act and minerals orientate perpendicular to the pressure direction.

According to this concept, if the foliation on a rock is running north-south, the pressure might be vertical (for instance, up to down) while minerals' weight helping in the process of foliation.

If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

What is a foliation?

Foliation on a rock means continuous multi layering on a metamorphic rock.

These layers can be thin as a sheet of paper.

Foliation occurs when the plain or elongated minerals inside a rock are pressed together and aligned.

Thus, If the foliation on a rock is running north-south, the tectonic pressure is coming from a vertical direction.

In horses, black coat color is influenced by the dominant allele (B) and chestnut coat color by the recessive allele (b). Trotting gait is due to a dominant gene (T), pacing gait to the recessive allele (t). What color horse would you use to find out the exact genotype of a black trotter? Explain.

Answers

Answer:

Bb or BB and Tt or TT

Explanation:

Black coat could be BB or Bb because it only needs one dominant allele for the trait to show up and the same goes for Tt and TT.

A large industrial company manufactures paper products such as paper towels and napkins using wood pulp. Which of these BEST describes why wood is considered to be a 'renewable' resource?

Answers

Answer: The question is incomplete because the options were not given but the options has been gotten from another website.

Here are the options.

a. Wood is routinely recycled to make new wood-based products.

b. Wood products can be manufactured from different tree species.

Eliminate

c. Wood may be replenished by planting new trees to replace those being used.

d. Wood products can be manufactured using various other materials such as plastics.

The correct option is c.

Wood may be replenished by planting new trees to replace those being used.

Explanation:

This is because wood is a Renewable resource because Renewable resources are resources that can be replenish or reproduce again after usage either by naturally producing another one. Theses resources are not exhausted because they can naturally be reproduce again. Wood is a Renewable resources because new ones are planted to replaced the used ones.

A student crested a model to show the flow of energy in a terrestrial ecosystem.

Which of the following correctly describes the way energy enters and leaves the ecosystem?

A Energy enters the ecosystem as sunlight, which is used by plants to produce sugars Energy leaves the ecosystem as heat from plants, herbivores, carnivores, and decomposers
B Energy enters the ecosystem from decomposers and is used by plants to produce sugars Energy leaves the ecosystem during cellular respiration
C Energy enters the ecosystem when it is transferred from the herbivores to the plants. Energy leaves the ecosystem as heat from plants, herbivores, carnivores and decomposers
D Energy enters the ecosystem as sunlight, which is used by plants to produce sugars. Energy leaves the ecosystem as mineral nutrients​

Answers

The flow of energy in the terrestrial ecosystem is initiated by the sun and its flows to plants and then animal life and finally reaches the decomposers. Thus the option A is correct.

What is an ecosystem?

An ecosystem is an ecological unit and its function is to balance the flow of energy in the environment. The flow of energy is unidirectional and as energy flow in one direction, it cannot be destroyed completely as it changes its form.

The energy that is received from the sun is transferred to the green plants, they include this energy to animals that are producers to consumers that include primary consumers and secondary consumers to decomposers, and then this energy leaves the system.

Answer:

Cause: Earth’s magnetosphere traps radioactive  solar wind particles in bands around Earth → Space travel through the Van Allen  belts is dangerous.

Cause: Earth is surrounded by a magnetic field → Effect: Solar wind deflects toward the poles.

Cause: Solar wind particles interact with Earth’s  upper atmosphere → Effect: An aurora is created

Explanation:

I have been able to drag the tiles to the correct boxes to complete the pairs.

When there is a trapping of radioactive solar wind particles in bands by the earth's magnetosphere, it becomes dangerous to travel in space through the Van Allen. Cosmic rays and solar particle add up to the additional hazards that it poses. A Van Allen radiation belt is known to be a zone  where energetic charged particles are found. Most of the energetic charged particles originate from the solar wind.  The solar wind  are captured by and held around a planet by that planet's magnetic field.

When the solar wind interacts with the earth's atmosphere, there is a collision of atoms of oxygen and nitrogen from the earth's atmosphere. The energy that is formed is a colorful glowing halo which is known as an aurora.

Answer:

Cause: Earth’s magnetosphere traps radioactive

solar wind particles in bands around Earth.
