What is difference between weather and climate class 9?

Weather includes the short-term changes of the atmospheric conditions, while climate is the observation of weather for a longer-term. Similar to the climate weather difference, the season is different from the climate.

What are the elements of weather?

There are six main components, or parts, of weather. They are temperature, atmospheric pressure, wind, humidity, precipitation, and cloudiness. Together, these components describe the weather at any given time.

What factors account for a location’s weather?

The five factors that determine the weather of any land area are: the amount of solar energy received because of latitude; the area’s elevation or proximity to mountains; nearness to large bodies of water and relative temperatures of land and water; the number of such storm systems as cyclones, hurricanes, and …

What factors change the weather?

Although many factors combine to influence weather, the four main ones are solar radiation, the amount of which changes with Earth’s tilt, orbital distance from the sun and latitude, temperature, air pressure and the abundance of water.

What are the 5 reasons for the seasons?

The reasons for the Earth experiencing seasons are revolution, rotation, tilt, axial parallelism, and sphericity – yikes! and I thought it had only to do with the tilt of the Earth! Let’s first look at revolution, which is Earth’s orbit around the sun.

Which factor has the biggest impact on Earth’s seasons?

The greater Earth’s axial tilt angle, the more extreme our seasons are, as each hemisphere receives more solar radiation during its summer, when the hemisphere is tilted toward the Sun, and less during winter, when it is tilted away.

What season has the greatest angle of insolation?

summer solstice

What determines the angle of insolation?

The angle of sunlight when it strikes Earth’s surface—called the angle of incidence—makes a big difference. The amount of insolation varies depending on latitude, the time of day, the time of year, and atmospheric conditions. Think about how a beam of light from a flashlight changes depending on its angle.

How does the angle of insolation affect intensity of insolation?

The intensity of insolation increases, as the angle of insolation gets closer to 90 degrees. The intensity of insolation decreases with an increase in latitude.

Where is the highest angle of incidence found?

Angle of Incidence Rays striking the planet’s surface from directly overhead — that is, at a 90 degree angle measured from the horizon — are the most intense. At most times and locations, the sun forms an angle with the horizon less than 90 degrees — that is, usually the sun sits lower in the sky.

What is the angle of incidence equal to?

Important Information. When light is reflected from a surface, the angle of incidence is always equal to the angle of reflection, where both angles are measured from the path of the light to the normal to the surface at the point at which light strikes the surface. This equality is known as the law of reflection.

What is the angle of incidence of a ray?

In geometric optics, the angle of incidence is the angle between a ray incident on a surface and the line perpendicular to the surface at the point of incidence, called the normal. The ray can be formed by any wave: optical, acoustic, microwave, X-ray and so on.

What is angle of incidence in social?

Definition of angle of incidence. : the angle that a line (such as a ray of light) falling on a surface or interface makes with the normal drawn at the point of incidence.

What is a normal angle?

Translation: A ray of light hits a surface at a point. From that point the line straight up, at 90 degrees to the surface, is called the normal. The angle between the normal and the ray of light is called the angle of incidence. You measure the angle from the normal, which is 0 degrees, to the ray of light.

What is the angle of normal incidence?

When a ray of light is incident on a surface at an angle equal to 0 degrees with the normal drawn at the point of incidence, that is called normal incidence.

What are the three laws of reflection?

Any mirror obeys the three laws of reflection, flat, curved, convex or concave.

What is reflection angle?

The angle between the direction of motion of the oncoming wave and a perpendicular to the reflecting surface (angle of incidence) is equal to the angle between the direction of motion of the reflected wave and a perpendicular (angle of reflection). …

How do you calculate refractive index?

Refractive index is also equal to the velocity of light c of a given wavelength in empty space divided by its velocity v in a substance, or n = c/v.

What is unit of refractive index?

Refractive index is the ratio of the speed of light in vacuum to the speed of light in the given medium and it is denoted by ′μ′. Unit of refractive index (μ) will be the ratio of the unit of speed of light in vacuum(c) to the speed of light in the given medium(v).

What is the refractive index of liquid?

The Theory: For example, the refractive index of water is 1.333, meaning that light travels 1.333 times faster in a vacuum than it does in water. The refractive index determines how much light is bent, or refracted, when entering a material.
