Answer:  The intertidal or littoral zone maintains a balance between the land and the sea. It provides a home to specially adapted marine plants and animals.

Explanation: The intertidal zone is the area where the ocean meets the land between high and low tides. A tide pool within Monterey Bay National Marine Sanctuary. Intertidal zones exist anywhere the ocean meets the land, from steep, rocky ledges to long, sloping sandy beaches and mudflats that can extend for hundreds of meters.

Answer:

1.  2)Hydrogen Bond

2. 1)Electromagnetic attraction

3. 2) A molecule with a positively charged end and a negatively charged end

4. 2.Hydrogen bonding

* i think i am right and i really hope so but please dont

count it against me babe.

explanation:

Individual hydrogen bonds are weak and easily broken; however, they occur in very large numbers in water and in organic polymers, creating a major force in combination. Hydrogen bonds are also responsible for zipping together the DNA double helix.

A hydrogen bond is formed when the positive end of one molecule is attracted to the negative end of another. The concept is similar to magnetic attraction where opposite poles attract. Hydrogen has one proton and one electron. This makes hydrogen an electrically positive atom because it has a deficiency of electrons.

A polar molecule is a chemical species in which the distribution of electrons between the covalently bonded atoms is not even. Some chemical species, such as chains of carbon molecules, share electrons equally and are said to be nonpolar molecules

Water molecules forming hydrogen bonds with one another. The partial negative charge on the O of one molecule can form a hydrogen bond with the partial positive charge on the hydrogens of other molecules. Water molecules are also attracted to other polar molecules and to ions.

The combustion temperature of a material determines whether a material melts or burns

Materials whose combustion temperatures are lower than their melting point gets burnt instead of melting, because before the temperature of the material is raised up to the melting point temperature,  the materials gets combusted at a lower temperature known as the combustion temperature

Melting is physical change and is controlled by the physical property ( melting point ) while burning is chemical change which is irreversible.

Hence we can conclude that The combustion temperature of a material determines whether a material melts or burns

Answer:

The melting of a glacier is an example of interaction among;

Hydrosphere, asthenosphere, atmosphere

Explanation:

The melting of a glacier is an example of the interactions among the Earth's cryosphere and hydrosphere

The cryosphere is described as the portions on Earth where water appears in solid (frozen) form such as glaciers, frozen grounds, snow covered land, sea ice, ice sheets, river ice, ice caps, etc.

The hydrosphere is all the forms water on a planet including, ice, liquid water and water vapor, therefore, the cryosphere is a part of the hydrosphere

The geosphere comprises the Earth's interior, including the asthenosphere, which is fluid and hot and therefore spread heat through both conduction and convection to the hydrosphere that raises the ocean temperatures and lead to glacier melting

The green house effect in the atmosphere results in global warming that raises the average temperature of the Earth which in turn raises the temperature of the oceans and the troposphere, resulting in melting of a glacier

Therefore, the melting of a glacier is an example of interaction among the hydrosphere, asthenosphere, and, atmosphere

Explanation:

when two tectonic plates move apart it causes a trench this is most common in oceans

Answer:In particular, ocean trenches are a feature of convergent plate boundaries, where two or more tectonic plates meet. At many convergent plate boundaries, dense lithosphere melts or slides beneath less-dense lithosphere in a process called subduction, creating a trench

Explanation:

Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter, causing the metal to stiffen and fracture. This is known as metal fatige. The bending causes that to occur.

A metal is a substance that has a shiny look when freshly processed, polished, or shattered, and conducts electricity and heat rather effectively. Generally speaking, metals are malleable and ductile.

These characteristics are the outcome of the metallic link that exists between the metal's atoms or molecules.

The earth's crust is where most pure metals are found. They are discovered in ores, which are solid materials from which metals and minerals may be extracted. The majority of the planet's iron mass, which makes up over a third of its mass, is located in its core.

Thus, Metals have a crystalline in nature, and a consistent shift in stress causes the structure to alter.

Answer:

It does not react with water, but reacts with most acids

Explanation:

Answer:

It doesn't react with water, but reacts with most acids

Answer:

22.22 g

Explanation:

The balanced reaction equation is;

Ca(s) + 2HCl(aq) → CaCl2(aq) + H2(g)

Number of moles of calcium reacted = 8.02g/40.1g/mol = 0.2 moles of Calcium

From the reaction equation;

1 mole of Ca yields 1 mole of CaCl2

Hence 0.2 moles of Ca also yields 0.2 moles of CaCl2

Mass of calcium chloride produced = number of moles * molar mass

Mass of calcium chloride = 0.2 moles of CaCl2 * 111.1g/mol = 22.22 g

A rumor spread faster in a classroom where students are confined to desks than in a gym where all of the students can move around freely.

The same applies to conductivity between metals and ionic solids because metals have more close particles.

Conductivity is the process by which a material is able to transfer electric charge or heat from one point to another without the actual movement of the particles of the substance.

The conductivity of substances varies from one substance to another.

The conductivity of solids is greater than the conductivity of that of other substances.

The conductivity of substances increases with a decrease in the distance between the particles of the substance.

Thus solids that have the closest particles have the highest conductivity.

Liquids have medium conductivity.

Gases have the least conductivity because they have the most spaced-out particles.

Answer:

D. There is no net change to the system

Explanation:

Equilibrium means "equal". In a chemical system, changes occur in substances called the reactants to produce another substance called the products. These changes from reactants to products and vice versa occur at an uneven rate until EQUILIBRIUM is reached.

In other words, equilibrium is attained when the reactants and products are formed at an equal or constant rate i.e. There is no net change to the system. For example, in the chemical system below:

A + B ⇌ C + D

This system is said to be at "EQUILIBRIUM" if the rate of reaction of the reactants (A and B) is equal to that of the products (C and D). That is, there is no net change (difference) in the reaction rate.
