A broad accumulation of stratified drift deposited adjacent to the downstream edge of an end moraine is a(n) ________. During the most recent ice age, glaciers covered about ________ percent of Earth's land area. The most abundant chemical sedimentary rock is ________.
The distal end of the femur articulates with the tibia in the lower leg and the patella or knee cap. The tibia below does not articulate with the patella. Between the condyles is the patellar surface that articulates with the patella or knee cap. These landmarks are important attachments for ligaments and muscles which will be discussed later in this unit. Another important anatomical component of the knee are the menisci.
