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.
In most cases it is at the underside of the leaf, as it does not want sunlight to dry it up.
The cuticle on the upper surface of a leaf helps to reduce water loss through evaporation and protect the leaf from damage. Since the underside of the leaf is not exposed directly to sunlight and does not play a major role in gas exchange, it does not have a thick cuticle layer.
Magma can flow if the upper mantle, leading to volcanic activity on the Earth's surface.
As the upper surface is covered with a waxy cuticle which protects the plant from dehydration if the stomata were covered by a cuticle they would not be able to function.

no it is in the middle of the underside

The tricep is the muscle on the underside of the upper arm. The muscle on the upper side is the bicep.

If you mean 'how' - not 'why' - air flowing over the wings is split into two streams. The stream flowing over the upper surface is lower in pressure to that on the underside - which creates lift.
The upper meniscus of the acid hematin is considered when taking a reading because it represents the true volume of the sample. The meniscus is the curve at the surface of a liquid caused by surface tension, and in this case, the upper meniscus accounts for any excess liquid or bubbles that may be present on the surface.
The underside of leaves is where the 'stomata' are to be found in most (not all) plants and it is through these stomata that the gas exchange occurs. The upper surfaces of leaves are usually tough and shiny to protect the leaf and shed water. If the stomata were on the upper surface and the leaf was wet, the water would block them and impede gas exchange.
The upper surface of groundwater is called the unsaturated zone. The unsaturated upper surface contains water, as well as spaces of air, particle grains and rocks.
The lower surface of the leaf has the stomata. You can see the reason for this if you cut a leaf in half from upper side to lower side. The upper portion of the leaf consists of tightly packed cells that are full of chloroplasts for taking in light. The lower half of the leaf is made up of loosely arranged cells. This allows room for air to enter the lower part of the leaf through the stomata and contribute carbon dioxide and take away oxygen. The upper surface of the leaf is covered by the cuticle which prevents dehydration, as such the stomata cannot be located or function on the upper surface
The term for the upper surface of the tongue is the "dorsum of the tongue."

The upper surface of water is called the water's surface or water level. It is the boundary where the water meets the air above it.
