Climate and Biomes. Climate. We have observed that plants require light, water, carbon dioxide, soil minerals and some reasonable temperature to survive. We have considered most of these factors and it is time to consider temperature, itself tied into all of these other factors in some way. This one environmental factor strongly determines the distribution of plants on the planet. Latitude. The Equator.
Stopping sight distance is the sum of two distances: (1) the distance traversed by the vehicle from the instant the driver sights an object necessitating a stop to the instant the brakes are applied; and (2) the distance needed to stop the vehicle from the instant brake application begins.
Sight distance, in the context of road design, is defined as the length of roadway ahead visible to the driver.[1] Sight distance is how far a road user (usually a vehicle driver) can see before the line of sight is blocked by a hill crest, or an obstacle on the inside of a horizontal curve or intersection.
