  Earth's atmosphere, on the other hand, is mostly nitrogen (78%) and oxygen (21%) with 1% being a mix of hydrogen, carbon dioxide and others. So you can see that Mars has much less atmosphere than the Earth does and oxygen make a proportionally much smaller fraction of of what there is than what we have on Earth.
Pickup trucks come in different shapes and sizes, and their weight entirely depends on the make and model. On average, a common pickup truck can weigh up to 3 tons, equivalent to 6,000 pounds.
A monster truck must weigh a minimum of 9,000 pounds, with some monster trucks weighing as much as 12,500 pounds. The less the body weighs, the more strength and weight can be put into the frame and engine without sacrificing speed and maneuverability. Average cost: $150,000 per truck.
