Explanation

Water is used for various recreational activities like swimming, rafting, and boating.

These activities promote physical health.

These are popular in tourism and leisure industries.

Explanation

The migration of people from rural to urban areas increases the demand for housing, often outstripping supply.

This rapid urbanization leads to overcrowding and a shortage of affordable housing in big cities.

Explanation

Peshawar is at a lower altitude than Murree, and atmospheric pressure decreases with increasing altitude.

Higher altitudes (like Murree) have thinner air and lower pressure, making Peshawar's atmospheric pressure greater.

Explanation

The ozone hole happens when the protective ozone layer in the stratosphere above the South Pole begins to thin every September.

All Important Questions Related to "OZONE"

The stratospheric ozone layer is Earth's “sunscreen”  protecting living things from too much ultraviolet radiation from the sun.

Oxygen layer in the atmosphere

Ozone protects us from the harmful ultraviolet radiation of the sun.

Ozone formula: O3

The ozone layer lies approximately 15-40 kilometers (10-25 miles) above the Earth's surface, in the stratosphere.

The ozone layer is depleting: Air pollution

Explanation

A monsoon is caused by a seasonal shift in the winds.

The winds shift because the temperature of the land and the temperature of the water are different as seasons change. 

monsoon season duration is April and September.

Explanation

Chlorophyll is a green pigment found in the chloroplasts of plant cells and is essential for photosynthesis

The process by which plants convert light energy into chemical energy to produce sugars from carbon dioxide and water.

Chlorophyll absorbs light energy, particularly in the blue and red regions of the visible spectrum,

While reflecting green light, giving leaves their characteristic green color.

This absorption of light energy by chlorophyll initiates the process of photosynthesis, allowing plants to produce their own food.

Explanation

A point source of pollution is a single, identifiable source from which pollutants are discharged, such as a factory or industry.

Industries release waste directly into air or water from specific locations.

Explanation

The approximate height of Earth's atmosphere is 6,200 miles (10,000 kilometers).

This is the approximate extent of the exosphere, the outermost layer of the atmosphere, which gradually merges with space. 

Explanation

All important questions and Information Related to 'Photosynthesis"

Photosynthesis takes place in presence of the following light Only in sunlight from the sun

Photosynthesis takes place faster in white light

Photosynthesis occurs more in blue and red light rays

Photosynthesis occurs more in blue and red light rays and less, or not at all, in green light rays.

Green Light light is more important for photosynthesis.

As compared to photosynthesis, glucose is chiefly decomposed during Respiration

At the time of a Solar Eclipse, the rate of photosynthesis will: Decrease

In all plants, the major sites of photosynthesis are Leaves

In Photosynthesis reduction occurs in the Water

At night, when photosynthesis is stopped, plants Give off Carbon Dioxide.

Photosynthesis pigments are organized into clusters called thylakoid

The process of photosynthesis produces glucose and carbon dioxide

Explanation

Cumulus clouds are fluffy, white clouds with a deep color at the base and are found near the Earth's surface.

They usually indicate fair weather but can develop into storm clouds (cumulonimbus).
