The world supply curve is considered perfectly elastic.
Horizontal.
The short-run aggregate supply curve is horizontal if the economy is operating below full capacity, meaning there are unused resources like labor and capital. This indicates that firms can increase production without raising prices, resulting in a flat supply curve.
The firm supply curve is horizontal in a perfectly competitive market because individual firms are price takers; they sell their products at the market price set by overall supply and demand. At this price, firms can sell any quantity they choose without affecting the market price. Therefore, they will supply as much as they can produce at that price, leading to a horizontal supply curve. If the price falls below this level, firms would not cover their costs and would reduce output to zero.
The difference between individual supply curve and the market supply curve is tat individual supply curve is like a firm. To be able to get the market supply curve you have to have the individual supply curve.
how is a market supply curve similar to and diffrent from an individual supply curve

The individual supply curve is the supply curve of a single firm producing output. Now say there are X individual producers there at any price P* the total available output is the output of all X producers ( a horizontal summation) this total of each individual supply curve gives the market supply curve. Put it simply all firms sell their output in the market.

A change in supply means that the supply curve has shifted. With a stable demand, this will result in a change in the quantity supplied but also a change in price. A change in only quantity supplied without a change in supply would require a horizontal supply curve. Alternatively a change in quantity supplied and price may occur if there is a shift of the demand curve.
Horizontal curve is a curve viewed in the x and y plane, while a vertical curve is viewed in the y plane only, or viewed from the side. Think of it like a cake. the top is the horizontal and the front is the vertical

A factor price taker faces a horizontal supply curve because it can hire as many units of the factor as needed at the market-determined wage rate, without affecting that rate. In contrast, the industry supply curve is upward sloping because as the quantity of a factor demanded increases, the price of that factor tends to rise due to increased competition for limited resources, leading to higher marginal costs for producers. Thus, while individual firms can take factor prices as given, the overall industry responds to changes in supply and demand, resulting in an upward-sloping curve.
A diagram of a perfectly competitive market typically shows a horizontal demand curve representing perfect competition, a horizontal supply curve at the market price, and a point where supply equals demand to show equilibrium. It also includes the producer and consumer surplus to illustrate market efficiency.
The demand / supply graph is designed to have supply on the vertical axis (Y) and demand on the horizontal (X). Thus you will have a higher supply = lower demand, or lower supply = high demand.
