Europe With the exception of Fennoscandia and northern Russia, few areas of untouched wilderness are currently found in Europe, except for various national parks. The main natural vegetation cover in Europe is mixed forest. The conditions for growth are very favourable. In the north, the Gulf Stream and North Atlantic Drift warm the continent. Southern Europe could be described as having a warm, but mild climate. There are frequent summer droughts in this region. Mountain ridges also affect the conditions. Some of these (Alps, Pyrenees) are oriented east-west and allow the wind to carry large masses of water from the ocean
Drift current same direction as the electric field, but the resulting conventional current points in the same direction as the electric field in both cases. If an electric field is applied to an electron in a vacuum, the electron will accelerate faster and faster, in approximately a straight line. A drift current looks very different than that up close. Typically, electrons are moving randomly in all directions (Brownian motion), frequently changing direction when they collide with grain boundaries or other disturbances. Between collisions, the electric field subtly accelerates them in one direction. So over time, they move at the drift velocity on
