The most important factors that determine the rate at which weathering occurs are the type of rock and the climate. Rainfall affects the rate of weathering.
The gas occurs by simple diffusion through the cells.
Gas exchange for photosynthesis - CO2 from the air diffuses into the leaf, and 02 diffuses out of the leaf into the air
A great example is perfume sprayed in a room. A person standing 15 ft away wont smell it right away, but after a minute or two (it has to diffuse through the air) the person will smell it. Also, if you drop a sugar cube in a glass of water, that basically gives you a perfect visual aid of diffusion. These are the 5 types that I know of: 1. Simple diffusion- occurs when molecules moves from a higher concentration to a lower concentration through a semi-permeable membrane without the assistance of proteins or use of energy. This is a form of Passive Transport. 2. Facilitated diffusion-occurs when molecules moves from a higher concentration to a lower concentration through a semi-permeable membrane with the assistance of proteins or but not the use of energy. This is a form of Passive Transport. 3. Active transport-occurs when molecules moves from a lower concentration to a higher concentration through a semi-permeable membrane with the assistance of proteins and the use of ATP energy. 4. Endocytosis- large amounts of molecules move toward the inside of a cell. This is a form of Active Transport. 5. Exocytosis- large amounts of molecules move toward the outside of a cell. This is a form of Active Transport.
What type of friction is air resistance?fluid friction. Air resistance is fluid friction. Air resistance occurs between the surface of a falling object and the air that surrounds it. Rolling friction occurs when a rounded surface moves over a solid and sliding friction occurs when a solid moves over another solid. Static friction occurs when a solid touches another solid but there is no movement.What two factors affect air resistance?size and shape. Size and shape are the two factors that affect air resistance. Air resistance works with surface area, so the more surface area, the more air resistance. Think about when you drop two pieces of paper: one crumpled and one flat. The crumpled one falls faster because there is less air resistance acting on the paper.
There is one reason on why diffusion is more quickly in today's world then in the past. It is because having better transportation.
Diffusion in gases is faster than in liquids because the particles in gas move way faster than in liquids. The gas particles therefore spread out more quickly and diffusion is completed faster.
Diffusion occurs on the cell membrane.

Diffusion of O2 and CO2 occurs at the alveoli in the lungs.

The intensity of light, concentration of carbon dioxide and temperature are the three main factors that affect photosynthesis. They determine the rate at which photosynthesis occurs.
distance involved =diffusion at short distances occurs at a greater rate than diffusion at long distances area involved= diffusion over short distance occurs at a greater rate than diffusion over long distances Barriers=thicker barriers slow down rates of diffusion
Diffusion occurs when there is a concentration gradient i.e. a substance moves from higher to lower concentration.
