Strom waves and ocean currents cause beach erosion.
What is beach erosion?
Sand is lost due to beach erosion, which is often caused by a mix of wind and water movement. Sand is moved to deeper water or to another coastal location by being scooped up off the beach. Beaches seem shorter and lower as a result of this process.
Sand particles make up the majority of beach deposits, and waves can quickly dissolve them.
These deposits are made up of terrestrial silt transported to the coast by rivers, marine sediment reworked from offshore deposits onto the coast, and sediment created by wave erosion of coastal landforms.
Therefore, Strom waves and ocean currents cause beach erosion.

How many dna molecules are in three pair of homologous chromosomes
Answer:
Thus during metaphase of mitosis, each chromosome (i.e., each chromatid pair) will contain two molecules
Explanation:
double stranded DNA (one molecule per sister chromatid). The following diagram depicts the behavior of one homologous pair of chromosomes during mitosis.
Six DNA molecules are there in three pairs of homologous chromosomes. This is because each homologous chromosome will contain two molecules of double-stranded DNA.
What do you mean by Homologous chromosomes?Homologous chromosomes may be defined as two chromosomes of the same length, position, and structure one inherited from the father's side and the other from the mother's side.
The amount of genetic material may vary from phase to phase of the cell cycle. But at the time of metaphase during mitosis, each chromosome will possess two molecules of DNA.

Describe what a convection current is. Explain how the Sun causes convection currents in the atmosphere. Then explain how these convection currents cause winds.
Answer:
Ok so i will try my best to describe the answers:
1) a convection current is like a boiling pot of soup. the burner heats up the soup on the bottom. hot air always goes up because the molecules become more active, making them space out upward. the hot soup travels up through the center of the pot, and the cold soup up top travels down towards the edges of the pot to replace the hot soup that just moved up. the process keeps on going and going until there is no more heat, or until the burner turns off.
2&3) the sun makes everything warmer, so when the sun touches Earth's surface, it warms up the air around it. as soon as the air warms up, it goes up into the atmosphere, like the pot of soup example. then, cold air from the top moves in to replace the hot air. with so many molecules of air moving at one time, it makes gusts of wind during the movement. when it is really windy, that means that there is a lot of hot air moving up and cold air moving down. when there is no wind, that means that every molecule is where it is supposed to be, not disturbing one another.
I hope this helps :D
The Sun's heating of the Earth's surface generates convection currents in the atmosphere. These convection currents, driven by differences in temperature and density, lead to the formation of winds as warm air rises and cooler air sinks.
The combination of convection currents and the Coriolis effect creates the intricate wind patterns and circulation systems that influence weather and climate across the globe.
A convection current is a process of heat transfer that occurs in fluids (liquids or gases) where warmer regions of the fluid rise while cooler regions sink. This phenomenon is driven by differences in temperature and density within the fluid. As a fluid is heated, it becomes less dense and rises, while cooler, denser fluid sinks to replace it. This movement forms a circular pattern known as a convection current.
The Sun plays a crucial role in generating convection currents in Earth's atmosphere. The Sun's energy reaches the Earth primarily in the form of sunlight. When sunlight strikes the Earth's surface, it warms the air close to the surface. Warmer air is lighter and less dense, causing it to rise. As this warm air rises, it creates a region of lower pressure at the surface. Cooler, denser air then rushes in to fill the void, creating a cycle of rising warm air and sinking cool air. This cycle sets up convection currents within the atmosphere.
Convection currents in the atmosphere are a major driving force behind the formation of winds. As warm air rises at the equator due to the Sun's heating, it creates a low-pressure area near the surface. Cooler air from higher latitudes flows in to replace the rising warm air, creating wind patterns. These wind patterns are known as the trade winds near the equator, prevailing westerlies in mid-latitudes, and polar easterlies near the poles.
Additionally, the rotation of the Earth (Coriolis effect) influences the direction of these winds, causing them to curve rather than blow in a straight line. This effect leads to the development of distinct wind belts and circulation patterns around the Earth.

What happens when carbon dioxide from the atmosphere dissolves in seawater.
Answer:
When carbon dioxide dissolves in seawater, most of it becomes bicarbonate ions and hydrogen ions. This increase in hydrogen ions is what decreases the pH. In addition, some of the hydrogen combines with carbonate to form more bicarbonate, decreasing the concentration of carbonate in seawater.
