The movement of the ocean and sea waves in a direction is called the ocean currents. Ocean currents can bring cold water, which cools the land and atmosphere.
What are the effects of ocean currents?Ocean currents are the movement of the oceanic waves by the influence of the gravitational forces that can affect the atmosphere and the climate of the region.
Oceanic currents are capable of carrying cold water from polar areas to the regions of the equator resulting in a cooling atmosphere over the geosphere.
Therefore, option B. oceanic currents carry colder air to the warmer regions.

2 Explain why the reaction between aluminum and iron oxide is useful in the railway industry.
Answer:
Sometimes, it is necessary to produce a small amount of iron more quickly, for example if railway workers need to produce molten metal to fix a broken rail.
Explanation:
The thermite reaction uses aluminium powder and iron (III) oxide. When ignited, the mixture reacts vigorously because of the large difference in reactivity between aluminium and iron.
The aluminum can create more durable bonds with oxygen than it can with hydrogen. Since a lot of heat is produced throughout the entire reaction, molten iron that may be used to link railroad tracks is produced as a result of the reaction.
What is aluminum ?Chemical element aluminum has the atomic number 13 and the symbol Al. Aluminum has a density that is around one third that of steel, which is lower than that of most common metals. It has a strong affinity for oxygen, and when exposed to air, creates a protective oxide coating on the surface.
Aluminum (Al) and iron(III) oxide (Fe2O3) react to generate aluminum oxide (Al2O3) and molten iron (Fe). Aluminum displaces iron in iron(III)oxide to generate aluminum oxide in what is known as a displacement reaction.
Iron oxide and aluminum are used to repair machine parts that have cracks or serve as railing on railroad tracks. Thermite reaction is the name given to this process.
Thus, The aluminum can create more durable bonds with oxygen than it can with hydrogen.

Which of the following adaptations does NOT help animals survive in areas covered with snow?
a thick fur to keep the body warm
a thick layer of fat that insulates the body
a dark-colored fur to catch their prey
a white-colored fur to hide from predators
Answer:
a dark-colored fur to catch their prey
Explanation:
In areas covered with snow, the temperatures are too low. Therefore, animals surviving in these areas require thick fur or body insulation to ensure their body temperature is regulated. The snow is white in color and therefore, being white in color helps the animals camouflage hence not visible to the predators.
Having a dark color, this will only expose these animals to their predators since the areas are covered with white snow. They will be easily traced by their predators and maybe selected out by nature.
38. Assuming a sample mixture made from sand and sugar had a mass of 53.5 g, and
it was separated using decantation and boiling to remove the water used in the
separation procedure, what is the mass percent of sugar in the sample assuming 35.2
g of sugar was recovered, and 16.0 g of sand was recovered?
A.66%sugar
B.4%sugar
C.30%sugar
39. Using the information from question 38 what is the total percent recovery for the separation? Is the percent recovery greater than less than 100% why might this be the case?
The Mass percent of sugar in the sample was 66% while the Total percent recovery is 95.7%
Equation
An equation is an expression used to show the relationship between two or more variables and numbers.
Given the sample had a mass of 53.5g, hence:
Mass percent of sugar in the sample = (35.2/53.5) * 100% = 66%
Total percent recovery = [(35.2 + 16)/ 53.5] * 100% = 95.7%
The Mass percent of sugar in the sample was 66% while the Total percent recovery is 95.7%

What force in liquids causes surface tension? covalent forces intermolecular forces intramolecular forces ionic forces.
Answer:
Intermolecular forces
Explanation:
Intermolecular forces cause surface tension.
Source info:
"Surface tension, capillary action, and viscosity are unique properties of liquids that depend on the nature of intermolecular interactions."
(11.S: Liquids and Intermolecular Forces (Summary)https://chem.libretexts.org )
Surface tension is said to be the result of the attraction between the particles present on the surface layer of the liquid matter. It is caused by intermolecular interactions. Thus, option b is correct.
What are intermolecular forces?Intermolecular interactions are the forces that are said to be secondary forces and allow the molecules to bond and interact together by the attractive and repulsive forces between the ions and the atoms.
The hydrogen bonds, ion-dipole, dipole-dipole, and dispersion forces are intermolecular interactions. They are not within but in between the molecules. They give rise to the surface tension in liquids that act cohesive and bind the various molecules in liquid together.
Therefore, option b. the intermolecular forces cause surface tension in liquids.

2Sr will be oxidation because it'll loses (2) electrons to O2. So, oxidised to form 2SrO
O2 will be reduction because it'll gain (2) electrons from Sr
Sr is oxidised. Thus, reducing agent because it causes O2 to be reduced.
O2 is reduced. Thus, the oxidising agent because it causes Sr to be oxidised.
