This unit is divided into 3 Arcs. Arc 1 answers the essential question, “What is weather and what factors influence
the weather?” The learning activities included in this arc guide students to use observation skills in order to
describe, explain, and predict weather patterns. Students will learn that the sun’s energy is the driving force of our
weather. They will complete activities to learn about wind, clouds, precipitation, temperature, and the role the
water cycle plays in our weather.
In Arc 2, students examine the essential question, “How does the ocean affect our weather?” Students will
complete activities to help them describe and explain the gulf stream, El Nino, La Nina, Sea and Land Breezes as
well as hurricanes.
Arc 3 allows students to investigate the essential question, “How does weather affect our lives?” Students will
complete activities to help them explain why our choices are based on the weather, as well as the impact that
climate change as on ecosystems. During the culminating activity in Arc 3, students research how to prepare for
extreme weather. Students have several opportunities to use their observations skills while working on their
nature journal
Explanation:
Weathering is the process by which rocks disintegrate into smaller fragments. Rock expands (with heat) and contracts (with cold) in response to temperature changes.
What is Weathering?Weathering is the deterioration of rocks, soils and minerals as well as wood and artificial materials through contact with water, atmospheric gases, and biological organisms.
Rock responds to temperature fluctuations by expanding with heat and contracting with cold. This is frequently observed with a weathering process known as Frost wedging, in which water freezes and thaws inside rock fissures. Salt wedging is a different type of weathering in which the salt that is left over after water evaporates can exert pressure on rock fissures.
Thus, Weathering is defined as the process by which rocks disintegrate into smaller fragments.

Carbon is found in different forms on the Earth. It is found as carbon dioxide in the atmosphere, as carbonate and bicarbonate salts in various minerals, as well as it occurs in the elemental form of diamonds and graphite. All biotic factors are based on carbon-containing molecules like carbohydrates, proteins, fats, nucleic acids and vitamins. Carbon is incorporated into life-forms through photosynthesis which is performed in the presence of sunlight by all life-forms that contain chlorophyll. Photosynthesis converts CO2 from the atmosphere or dissolved in water into glucose molecules. These molecules are either converted into other substances or used to provide energy for the synthesis of other biologically important molecules.
The use of glucose to provide energy to living things involved the process of respiration in which oxygen may or may not be used to convert glucose back into CO2. This CO2 goes back into the atmosphere again. The process of combustion also adds to the level of carbon dioxide in the atmosphere. This percentage is said to have increased when human beings started cutting down trees, burning fossil fuels, etc. on a very large scale. Thus, carbon is cycled repeatedly through different forms by the various physical and biological activities and this cycle is therefore called carbon cycle.
Hope you could get an idea from here.
Doubt clarification - use comment section.
Carbon cycle is a biogeochemical cycle in which the carbon atom continously moves in the atmosphere through different forms and processes.
What is Carbon cycle?The carbon cycle is the biogeochemical cycle which describes the process through which carbon atoms continually travel from the atmosphere to back to the Earth and then back into the atmosphere. This cycle goes on repeatedly. Since our planet and its atmosphere forms a closed environment, the amount of carbon in this system does not change, it only transforms from one form to another.
The processes which takes place in carbon cycle include photosynthesis, decomposition, respiration, and combustion. Carbon cycles from the atmosphere into the plants and living things. For example, carbon is a pollutant in the atmosphere which is present as carbon dioxide gas.
Carbon moves from the plants and animals to soil. When the plants and animals die, their bodies, wood, and leaves decays which being carbon into the ground. Some of this carbon is buried and become fossil fuels in millions of years. Carbon moves from living things to the atmosphere through respiration in which they inhale oxygen gas and exhale carbon dioxide gas.

Which is an example of a limiting factor that is dependent on population size?
Answer: Food can be an obvious answer because people will not survive without food so they will die. And death means there will be a decrease on population size. So food can be a limiting factor that is dependent on population size.
Answer:
A limiting factor that depends on propulation size is called a density-dependent limiting factor.
Density- dependent limiting factors include: competition, predation, parasitism and disease.

Why does a cis fatty acid have a kinked shape?
Answer:
Steric hindrance in the cis orientation causes the chain to take on a more bent shape. Most natural unsaturated fatty acids are in the cis conformation. As can be seen in Figure 2.327, the cis fatty acids have a more of kinked shape, which means they do not pack together as well as the saturated or trans fatty acids

Which of the following is a problem that could result from poor monitoring of free range grazing?
The increased use of antibiotics
The additional exposure of soil layers
The prevention of invasive plant species
The higher rates of mental illnesses in animals
Answer:
The additional exposure of soil layers.
Explanation:
Antibiotics are administered by humans, so less contact with humans won't cause an increased use of antibiotics. The prevention of invasive plant species is not a problem, nor would it be caused by improper management of free range animals. Mental Illness in animals is usually caused by being put in small enclosure or living in poor conditions, not by being allowed free range. Therefore, the answer is the additional exposure of soil layers, since excessive grazing can decimate plant and soil layers.
