The general recommendation is the 20% rule. The rider should not be heavier than 20% of the horse's weight. A horse or pony can carry up to 20% of its own body weight. The rider AND the tack should weigh no more than 240 lbs. Assuming you are riding Western, the rider should weigh no more than 200 pounds. If you are riding English, the rider should weigh no more than 215 lbs.

What ocean does the Ring of Fire encircle? o Most active volcanoes on land are located along the margins of the ocean basins notably within the circum- Pacific belt known as the Ring of Fire ( Figure 7.33).
The greatest number of the Earth's volcanoes occur on the ocean floor. ROV Jason gets a close view of magma explosions and lava flows on West Mata volcano. Volcanic eruptions occur only in certain places and do not occur randomly.This is because the Earthâs crust is broken into a series of slabs known as tectonic plates. These plates are rigid, but they âfloatâ on a hotter, softer layer in the Earth's interior.lthough most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth's volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.
