Calf (leg) The calf (Latin: sura) is the back portion of the lower leg in human anatomy. The muscles within the calf correspond to the posterior compartment of the leg. The two largest muscles within this compartment are known together as the calf muscle and attach to the heel via the Achilles tendon. Several other, smaller muscles attach to the knee, the ankle, and via long tendons to the toes.
Wind is caused by unequal air pressure formed when the sun heats the earth's surface unevenly. As such, if one part of the earth is heated and another part isn't, the wind wil â¦ l blow from the former to the latter, regardless of the direction that is. 3 people found this useful.
Slope winds are local diurnal winds present on all sloping surfaces. They flow upslope during the day as the result of surface heating, and downslope at night because of surface cooling. Slope winds are produced by the local pressure gradient caused by the difference in temperature between air near the slope and air at the same elevation away from the slope.
