Which of the following best explains how subsoil becomes rich in minerals?

Answers

Answer 1

Minerals from the topsoil leach down into the subsoil. Volcanic activity heats the rock fragments in the subsoil and releases minerals. Groundwater flows through the subsoil and deposits minerals. The bedrock below the subsoil is broken down into smaller particles.

what things can be determined from a cross-section of a tree trunk?

Answers

Answer:

A cross-section of a tree trunk, also known as a tree cookie or tree round, can provide various pieces of information, including:

Age of the tree: The number of growth rings in the cross-section can be counted to determine the age of the tree.

Growth patterns: The thickness and width of the growth rings can provide information about the growth patterns of the tree, including periods of rapid and slow growth.

Environmental conditions: The width and color of the growth rings can also provide information about the environmental conditions the tree experienced during its life, such as droughts, fires, or disease.

Wood type: The type of wood and its density can be identified from the cross-section, which can help in determining the species of the tree.

Health and vitality: The appearance of the wood, such as cracks, decay, or insect damage, can provide information about the health and vitality of the tree.

Historical events: In some cases, the cross-section may also contain evidence of historical events, such as bullet holes, carvings, or scars left by fires or lightning strikes.

Overall, a cross-section of a tree trunk can provide valuable information about the history, growth patterns, and environmental conditions of a tree, and can be used by scientists, researchers, and arborists to better understand and manage forest ecosystems.

Answer: Tree trunk thoughts

Knowing that you have a tree that is "cross-section" of a tree, there are severl but the most common reasons are, disastrous floods, insect attacks, lightning strikes, and even earthquakes. These can be reason of this question.

Internal and External Structures

You are now going to construct an argument that plants have internal and external structures that support growth and reproduction.

Choose the internal and external structures you want to gather evidence and create a statement about.

subject: sciences

Answers

Explanation:

Some structures are internal, like the lungs, brain, or heart. Other structures are external, like skin, eyes, and claws. Some structures are unique, like the long neck of a giraffe. Other structures are more common, like a heartStructure and Function: Plants and animals have both internal and external structures that serve various functions in growth, survival, behavior, and reproduction.

Plants have internal and external structures just like us humans do. While humans internally have lungs, a heart, and intestines Plants have that to. Plants have different fibers that allow the it to move water, make food, do photosynthesis, etc. So for this you could pick a couple different plant fibers such as the sclerenchyma fiber and the parenchyma fiber. The sclerenchyma fiber allows the plant to come out of the ground. This fiber is essentially its bones. The parenchyma fiber allows photosynthesis to occur. It moves water creates food etc.

Answer:

C, Humans are adding carbon faster than the environment can take up and store carbon.

Explanation:

The other answer choices don’t make sense. Humans are impacting the carbon footprint at a much quicker rate & far more heavily so than other organisms. Hope this is correct & helps you out:)

The statement that best describes the concern scientists have about the carbon cycle is : ( C ) Humans are adding carbon faster than the environment can take up and store carbon.

The increase in the rate of industrialization globally has caused a tremendous increase in the rate of fossil fuels been burnt and the increase of gas flaring activities during oil exploration.

The increased burning of fossil fuels adds Carbon more rapidly into the atmosphere than the amount of carbon leaving the atmosphere into carbon deposits.

Hence we can conclude that The statement that best describes the concern scientists have about the carbon cycle is : ( C ) Humans are adding carbon faster than the environment can take up and store carbon.

answer B.

it’s melting

From the diagram of the rock cycle the missing part is ( B ) ; Melting

Magma is a hot liquid/semi-liquid rock that is usually formed under the earth due to high pressure and temperature present in the inner core of the earth. magma is obtained by the melting down of existing rocks ( Igneous, sedimentary and metamorphic rocks ) under high pressure and temperature in the earths core.

Magma is released to the earth surfaces during volcanoes therefore the missing term in the rock cycle is melting

C.) a seafloor that was geologically active with earthquakes, volcanoes, and mountain chains

D.) mountains in North America appearing to match up with mountains in Northern Europe

Answers

Answer is “D” mountains in North America appearing to match up with mountains in Northern Europe

The piece of evidence that Alfred Wegener's original theory of continental drift has access to is the mountains in North America appearing to match up with mountains in Northern Europe. Thus, the correct option for this question is D.

What is Continental drift?

Continental drift may be defined as a type of hypothesis that represents a gradual movement of the Earth's continents over geologic time relative to each other. This movement of the Earth's continents results from the motion of tectonic plates.

According to Alfred Wegener's original theory of continental drift, the continents of the Earth have been adjoined together and have migrated away from each other at different times in the history of the Earth.

This reflects that mountains in the continent of North America appear to match up with the mountains in the continent of Northern Europe.

Therefore, the correct option for this question is D.
