Warmer, colder
Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.
Warmer fluid is less dense so it rises and colder fluid is more dense so it sinks.
Binocular vision, the ability to focus both eyes on the same object at the same time, usually does not develop until 4-5 months of age.
Binocular vision is the type of vision in which both the eyes look in the same direction to form a 3-D image of the object. One single image is formed by both the eyes. When any disorder appears regarding the binocular vision, the core reason is the misalignment of both the eyes.
Eyes are the organs of vision. They are present in a pair embedded in a socket like region on the skeleton below the forehead. The image is formed at the retina of the eye. The image formed is an upside down image.
