As far as I know, it's sand.
A jump is measured from the foul line to the first spot where the athlete touched in the sand pit.
Long jump is measured from the takeoff line to the closest landing point in the sand pit. The distance is measured in meters from the edge of the takeoff board where the athlete's foot leaves the ground to the mark left by the athlete's nearest body part.
The long jump consists of four key elements: approach run, takeoff, flight, and landing. The athlete must generate speed during the approach run, execute a powerful takeoff from the takeoff board, maximize distance during the flight phase using proper technique, and land securely in the sand pit to complete the jump.
Typically, a jump rope weighs between 100 to 300 grams, depending on the material and design. The weight can vary based on factors such as the length and thickness of the rope, as well as any additional features like weighted handles.
A long jump measures an athlete's ability to generate power and speed before leaping to cover a horizontally extended distance. It tests explosive strength, coordination, and technique to achieve the farthest jump possible.
just that: the sand pit.

On average the Olympic pit is 24.75m2 on the top.
Two events in athletics use a sandpit: the long jump, and the triple jump.

It varies between different types of ages and skill level. Meaning that a school long jump pit would probably be different then a pit in the Olympics.
The long jump boards are the white lines that line the run way of the pit. These lines are certain lengths away from the edge of the pit. For outdoor the distances from the board to the pit are 4' 8' & 12' in indoor the distances away from the board are 5' & 10'
5 metres exact
The size of the long jump and triple jump pits in the Olympics typically measures about 2.75 meters wide and can vary in length, usually around 10 meters or more, depending on the specific venue and event requirements. The depth of the pit often ranges from 0.5 to 1 meter to ensure adequate safety and landing conditions for athletes. Each pit is filled with a special material, such as sand or a synthetic surface, to cushion the landing.
