Knee joint - femur and tibia.

Hip joint - pelvis and femur.

Shoulder joint - scapula and humerus

Elbow joint - humerus, radius and ulna

Sacroiliac joint - sacrum and ilium.

<h3><u>Explanation:</u></h3>

The joints are defined as the connection between two adjacent bones which makes different structures. Joints are of different types - some are movable, while some are immobile.

The knee joint is a hinge joint which is a movable joint between the femur and tibia. This joint has synovial capsule, as well as synovial fluid to help in the movement. Knee joints are movable only in one axis.

Hip joint is also a mobile joint, between the femur and the acetabulum cavity of pelvis. This joint is a ball and socket joint, movable in all axis.

Shoulder joint is very similar to hip joint, being synovial joint. This joint is between the facet of scapula and humerus. This joint is the most movable joint of a human body, being able to rotate a complete of 360°.

Elbow joint is very similar to knee joint, which is also a movable joint between the humerus and radius- ulna. It's also a hinge joint, movable in one plane.

Sacroiliac joint is an immovable joint between the sacrum and ilium, which joins the pelvis with the vertebral column. This joint isn't a synovial joint.

Answer: The average global temperature has increased by a little more than 1°. The temperatures we experience locally and in short periods can fluctuate. In the past, a one- to two-degree drop was all it took to plunge the Earth into the Little Ice Age. The strong warming trend of the past four decades likely reflects a shift

Technological advances had helped reveal that the ocean floor was not flat, as once believed, but instead was marked by 50,000-k

poizon [28]

<span>By the late 1960s, scientists had developed the theory of plate tectonics based on a range of new evidence. Technological advances had helped reveal that the ocean floor was not essentially flat, as once assumed, but instead was marked by 50,000-kilometer-long (31,000-mile), 3,000-meter-high (9,800-ft) ridges and 11-kilometer-deep (7-mile) trenches. Scientists found striking patterns related to these features. They found that the youngest oceanic crust is located nearest the mid-ocean ridge and the oldest crust is nearest the trenches. They also detected a pattern of alternating magnetic polarity along the ocean floor, which emanated from the ridge tops. These two pieces of evidence, coupled with the fact that volcanic activity and island-building occurred most commonly at ocean trenches, suggested that new crust was created at mid-ocean ridges and destroyed at ocean trenches. Scientists Harry Hess and Robert Dietz used this evidence to revive and expand Holmes' convection theory into the theory they called "seafloor spreading." Finally, Wegener's notion of continental drift was coupled with a mechanism that could explain the movement of tectonic plates.</span>
