Answer:
D. astigmatism
Explanation:
Astigmatism is an imperfection in the curvature of the eye. Most of the focusing power in the eye occurs along the frontal surface called the cornea. The next structure involved in focusing is the lens, which lies behind the iris inside the eye.
The ideal cornea has a symmetrically curved surface, like a basketball. Astigmatism is caused by a cornea or lens with a curve that is not symmetrical. As a result, people with astigmatism may have distorted or blurred vision.
Astigmatism can occur in families and in most cases is associated with other refractive problems such as nearsightedness or farsightedness. It may also increase over time due to age.
Winds near the surface move across the isobars at an angle when the frictional force, pressure gradient force, and apparent Coriolis force are combined.
<h3>What is the motion of horizontal and vertical air in a high-pressure anticyclone and in a low-pressure cyclone?</h3>
Winds near the surface move across the isobars at an angle when the frictional force is combined with the pressure gradient force and the apparent force of the Coriolis effect. Consequently, the air spirals and converges as it advances in the direction of low pressure. A cyclone sometimes referred to as a low-pressure system, is created by this spiraling inward toward a center of low pressure. Convergence is the technical term for this inward spiraling action, which likewise raises the air at the center.
Air spirals downward and outward from an anticyclone, also known as a high-pressure system, in a high-pressure area. Divergence is the name for this spiraling outward motion. Cyclones rotate anticlockwise in the northern hemisphere and clockwise in the southern hemisphere.
