Soil is formed by the weathering of rocks which takes place over millions of years. Hence, soil formation is a slow process.
Soil formation takes place in different layers namely topsoil, subsoil, partly weathered rock and parent rock or bedrock.
The topsoil is rich in humus and supports all types of vegetation. Subsoil consists of sand, silt, clay and holds moisture.
Factors Responsible for Soil Formation :The parent rock determines the colour, the texture and mineral composition.Climate controls the rate of weathering, time decides the maturity of soil.Plants and animals contribute to humus formation and the relief of the land determines the accumulation of soil.Answer:
Soil minerals form the basis of soil. They are produced from rocks (parent material) through the processes of weathering and natural erosion. Water, wind, temperature change, gravity, chemical interaction, living organisms and pressure differences all help break down parent material.

Compare a sled’s potential energy at 10 m to its potential energy at 20 m. How does doubling height affect potential energy?
Answer:
It has an exponential effect. In contrast, you can reach a point when an object is so heavy that when dropped, it achieves terminal velocity. Without the factors of drag and general friction, all objects will fall at a velocity of around 9.8 meters per second. They must, however, accelerate to that speed. Increasing the high gives the sled more time to reach its top speed. That is, its potential energy grows.

This plant structure is responsible for producing leaves, transporting water and nutrients, and support the plant.
A) Roots
B) Seeds
C) Flowers
D) Stems
Answer:
D) Stems
Explanation:
Stems are a part of a plant that are responsible for various things. Their main responsibility is to support the plant, this is through holding up the leaves, flower, and buds. Stems also take nutrients and water from the roots in the ground and transport that up the stem and into the other parts of the plant. Lastly, leaves grow out of the stem, so it is responsible for that as well.

Why does social science intersect with marine science?
A. Many poems and novels are written about the ocean.
B. Human behavior causes a lot of issues with the ocean.
C. Social science is another important branch of the sciences.
D. These are very different disciplines that have little connection.
Answer:
it's either b or d I think
Social science intersects with marine science because human behavior causes a lot of issues with the ocean.The correct option is B.
The ocean is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water, making Earth an ocean world. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided.Distinct names are used to identify five different areas of the ocean: Pacific , Atlantic, Indian, Southern, and Arctic.
Seawater covers approximately 361,000,000 km² of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.Pollution of water by human activities makes the marine science intersect with social science.
Thus, option B is correct.

What happens in the original cell so that each of the daughter cells has a complete set of chromosomes
Answer:
The DNA gets copied equally through a process called mitosis and the copied DNA(chromosomes) are split equally among the daughter cells.
Can someone explain this?
How did the first small organic molecules form in earth’s earliest atmosphere? There are two main theories discussed. Make sure you know both. Refer to Miller and Urey experiment and meteorite theory
zapped gas/liquid into amino acids
many amino acids thought to have come from meteorites
a mixture of gases and water that Miller thought were present on early Earth was heated and zapped with electricity to mimic lightning. This created five identifiable amino acids
newscientistcom
We know amino acids exist in some kinds of meteorites and interplanetary dust
Many left-handed amino acids were found inside the Murchison meteorite. Most were kinds not found on Earth.
92 different amino acids have been identified in the Murchison meteorite. Of these, only 19 are also found on Earth. The remaining amino acids have no apparent terrestrial source. This discovery led scientists to consider the possibility that Earth's life forms originated elsewhere in the universe. And the same cosmic process that may have helped life arise on Earth could also be seeding life elsewhere in the universe

and through human activities like burning of fossil fuels...
The respiration process adds carbon dioxide to the air. Therefore, option "C" is correct.
What is respiration?A metabolic process known as respiration involves an organism's living cells taking in oxygen and releasing carbon dioxide from the oxidation of complex organic substances to obtain energy (ATP). High-impact breath happens in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The synthetic condition is C6H12O6 + 6O2 → 6CO2 + 6H2O.
There are two types of respiration that occur in nature that is aerobic respiration and anaerobic respiration. Aerobic respiration involves the use of oxygen for oxidation and later oxygen is not used.
