Explanation:
Identify/describe how the process of physical weathering breaks down materials at the Earth's surface (by the following change agents: water movement, freezing, abrasion/pressure, exfoliation. plant growth, and animals).
Explain the role of each factor in chemical weathering (water, acid, and air).
Answer:
Exfoliation: When temperature of rocks rapidly changes that can expand or crack rocks.
Freeze-Thaw: when water gets into a crack, and it freezes ; the crack gets wider
Plant Growth: this is when a seed falls into a crack in a rock, and breaks apart the rock with its roots.
Animals: small animals like moles and mice can burrow into a rock and crack it open

How can knowing the formula for the area of a circle help you to remember the formulas for the volume of a cylinder and the volume of a cone?
Answer:
Your solution is given in the explanation below. Brainliest? :D
Explanation :
The radius or diameter of the circular base or top, as well as the height of the cylinder, are required to compute the volume of a cylinder. A cylinder's volume is equal to the product of the area of its circular base and its height. A cylinder's volume is measured in cubic units. Recall the acronyms for base (b), height (h), and side (s) since they are essential for these calculations to remember surface area and volume formulae.
A cylinder and cone both have circular faces and in both their formulas you need the area of the circular face multiplied by the height (cylinder) or height/3 (cone). So if you know the formula for the area of a circle, you know half of the formulas for the volume of cylinder or cone!
Hope this helps! :)

Which is a true statement about the following chemical formula?
2(C6H12O6)
A.The formula is a molecule but not a compound
B.There are 18 molecules in this formula
C.There are 2 molecules in this formula
Answer:
Your answer is C (I think I'm not absolutely sure)
Explanation:
There are two types of chemical compound one is covalent compound and another is ionic compound in chemistry. In ionic bonds, electrons are completely transferred. The correct option is option C.
What is chemical Compound?Chemical Compound is a combination of molecule, Molecule forms by combination of element and element forms by combination of atoms in fixed proportion.
Covalent compounds are formed by covalent bond and ionic compounds are formed by ionic bond. Covalent bond is formed by sharing of electron and ionic bond are formed by complete transfer of electron. Ionic bonds are stronger than covalent bonds.
C₆H₁₂O₆ is a molecular formula for glucose. C₆H₁₂O₆ represents one molecule of glucose. 2(C₆H₁₂O₆) represents two molecule of glucose.

Chemical weathering affects hillslope form by directly removing mass from hillslopes. The transformation of primary minerals to secondary minerals can also affect the hydrology, biota, and stability of hillslopes, which in turn influence sediment transport and landscape morphology. Erosion in evolving landscapes can modulate and be modulated by chemical weathering; for example, pulses of accelerated erosion can lower the residence time of hillslope materials, thereby increasing their chemical weathering rates, which in turn accelerate the incision signal.

Describe what you know about this chemical formula: 4CO2
Answer:i hope im not too late
Explanation:
4CO2 also known as 4CO2 is a chemical compound occurring as an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. It also helps trap earths heat inside the earth so i doesnt escape back to outer space.
yourwelcome goodluck ill peel my eyes out if need help again- an 8th grader :p
Carbon dioxide is formed by the covalent bonding of carbon and two oxygen atoms. Thus it is a having the formula CO₂. 4CO₂ means 4 moles of carbon dioxide.
What is carbon dioxide?Carbon dioxide is an inorganic gas formed by the covalent bonding of carbon and oxygen. The valency of carbon is four and the valency of oxygen is two. Thus carbon shares its electrons two to each oxygen.
Each oxygen in turn shares its two electrons with carbon. Thus both the atoms attains stability. Carbon dioxide is a nonpolar compound with the formula CO₂. Thus one mole of carbon is represented as CO₂.
One mole of CO₂ weighs 44 g. Hence, the molar mass of carbon dioxide is 44 g/mol. As any other compounds one mole of carbon dioxide contains Avogadro number of atom or 6.022 ×10²³ CO₂ molecules.
4 CO₂ indicates 4 moles of CO₂ having 4 × 6.022 ×10²³ =24.08 ×10²³ molecules.

Kinetic energy can never be greater than the ____________________ energy pendulum
Answer:
your answer is potential
Kinetic energy can never be greater than the potential energy in a pendulum
Explanation:
Please mark as brainliest
Kinetic energy can never be greater than the potential energy pendulum. A moving object as well as particle has kinetic energy.
What is kinetic energy?Kinetic energy is a type of power that a moving object or particle possesses. An item accumulates kinetic energy when work, which involves the transfer of energy, being done on it by exerting a net force.
A moving object as well as particle has kinetic energy, which relies on both its mass and its rate of motion. The type of motion might be vibration, rotation on an axis, translation (or travel along a path through one point to another), or indeed any combination of these. Kinetic energy can never be greater than the potential energy pendulum.
Therefore, kinetic energy can never be greater than the potential energy pendulum.

When is the Law of Conservation of Mass not true? I am so confused...
Answer:
When one of the products of the equation is a gas. The gas escapes and isn't weighed and what is left is not the total mass of the system.
Explanation:
;)
Answer:
The conservation of mass does not apply if the system is open and energy escapes. However, it does continue to apply to totally closed/isolated systems. Therefore, if energy cannot escape a system then its mass cannot decrease.
