Effect of Sun angle on climate sunlight shines on the earth at a lower angle (Sun closer to the horizon), the energy of the sunlight is spread over a larger area, and is therefore weaker than if the Sun is higher overhead and the energy is concentrated on a smaller area. Figure 2 depicts a sunbeam one mile (1.6 km) wide falling on the ground from directly overhead, and another hitting the ground at a 30° angle. Trigonometry tells us that the sine of a 30° angle is 1/2, whereas the sine of a 90° angle is 1. Therefore, the sunbeam hitting the ground at a
Less than truckload shipping Less than truckload shipping Less than truckload shipping or less than load (LTL) is the transportation of relatively small freight. The alternatives to LTL carriers are parcel carriers or full truckload carriers. Parcel carriers usually handle small packages and freight that can be broken down into units less than . Full truckload carriers move freight that is loaded into a semi-trailer. Semi-trailers are typically between and require a substantial amount of freight to make such transportation economical. There are several different perspectives as to what is actually considered LTL. Full Truck Load carriers can put anywhere from 2 to 6
