Why do some surfboards have more than 1 fin located on the underside of the board?
Fins control the surfboard, its depth helps it hold in turns, a longer fin base will give you more speed, and a longer rake angle gives tighter turns, additional fins increase these attributes, tight turns especially require fins that are positioned close to the outer edges of the surfboard as a good portion of the bottom will be out of the water, that is why most single fin boards are for cruising or medium wave riding.

Why does the underside of the leaf gives off more bubbles than the upper surface?
The underside of the leaf typically produces more bubbles than the upper surface due to a higher concentration of stomata, which are small openings that facilitate gas exchange. These stomata are primarily located on the lower surface to minimize water loss while allowing for the uptake of carbon dioxide during photosynthesis. As a result, more bubbles, which represent oxygen released during this process, are observed from the underside where photosynthesis is more active.
Where is the stomata located to reduce water loss?
Stomata are typically located on the underside of leaves. This positioning helps to reduce water loss by minimizing exposure to direct sunlight and reducing the chances of evaporation. The presence of stomata on the underside of leaves also reduces the risks of damage from external factors such as wind and heat.
How are the top and underside of a leaf different?
The top of a leaf is typically more flat and has a waxy coating to help prevent water loss, while the underside tends to be more porous with stomata for gas exchange. The top side often contains more chlorophyll for photosynthesis, while the underside may have hairs or specialized structures for protection or capturing nutrients.
Where on the leaf is the stomata found and how to prove that?
Stomata are found on the underside of plant leaves. To prove this, you can use a microscope to observe and identify the stomata on a leaf's underside. Staining techniques can also be employed to make the stomata more visible for identification.
In photosynthesis which surface has more stomata?
In photosynthesis, the underside of leaves typically has more stomata than the upper surface. This adaptation helps minimize water loss while still allowing for gas exchange, as the lower surface is less exposed to direct sunlight and wind. By having more stomata on the underside, plants can effectively regulate transpiration and optimize their photosynthetic efficiency.
Are snowboards more expensive than surfboards?
The prices of snowboards and surfboards tend to be about the same. Surfboards are a lot larger, so one would think they would be more expensive. However, when buying a snowboard, it's important to remember that one will also have to buy boots and bindings to keep oneself attached to the board at all times.
How have surfboards changed over the years?
Surfboards have become lighter, stiffer, shorter, and their keels have become more advanced hydro-dynamically.
What is the little spikey tool that looks like a comb of some sort used for in the pocket of board shorts?
It's a wax comb for roughing up the wax on surfboards to make it more grippy. You get it in some wetsuits too.
How have surfboards changed over time?
Surfboards have evolved over time with improvements in materials, shapes, and technology. Early surfboards were made from wood and were heavy and difficult to maneuver. Modern surfboards are typically made from lighter materials like foam and fiberglass, and come in a variety of shapes and sizes to cater to different styles of surfing. Technology has also played a role, with innovations like computer-aided design helping to create more efficient and high-performance surfboards.
Did Sears Roebuck sell surfboards?
Yes, Sears Roebuck sold surfboards, particularly during the surfing boom of the 1960s and 1970s. They offered a variety of surfboards, including models for beginners and more advanced surfers, often through their catalog and retail stores. The company aimed to cater to the growing popularity of surfing at the time.
What stores have the cheapest surfboards?
Among the stores that have the cheapest surfboards are eBay and Walmart. It is however important that you focus on the quality of the product as well as buying a very low quality surfboard means spending more money for replacement when it is broken.
Why does the underside of the leaf gives off more bubbles than the upper surface?

What are the shapes of the surfboards?
1.- The 'fish', which is a board that is thicker and more stable. 2.- The 'shortboards' or "thrusters" that are used by the more experienced surfers. 4.- The 'gun' surfboard, which is used for big wave surfing. They are long, but narrow. 5.- The 'longboards', which are very easy to get up on and have a larger area to stand on. These are VERY good for beginners.
Where do you find the engine core plug on a previa?
their are 4 on top of the engine under drivers seat 4 more are located on the underside of the engine behind the oil sump
Where is the stomata located to reduce water loss?
Stomata are typically located on the underside of leaves. This positioning helps to reduce water loss by minimizing exposure to direct sunlight and reducing the chances of evaporation. The presence of stomata on the underside of leaves also reduces the risks of damage from external factors such as wind and heat.
Why are spore bags at the underside of a leaf?
Spore bags, or sporangia, are typically located on the underside of a leaf to protect them from environmental factors such as direct sunlight and moisture loss, which can be detrimental to spore viability. This positioning also helps reduce the risk of predation by herbivores and allows for better dispersal of spores with the wind. Additionally, the underside of leaves often has a more humid microclimate, promoting spore development and release.
What number is located in the center of a dart board?
The number located in the center of the dart board, or more commonly known as the "bulls eye" is worth a total of 50 points. As for the outer part of the bulls eye, it is worth 25 points if a dart were to land there.
