Explanation

The renewable energy sources are:

• Water energy
• Wind energy
• Tidal energy
• Hydroelectric
• Ocean energy
• Geothermal energy
• Biomass
• Biogas

The non-renewable energy sources are:

• Fossil fuels or Hydrocarbon fuel (Oil, Natural gas, Coal)
• Nuclear energy

Explanation

The human cell contains 46 chromosomes.

These are organized into 23 pairs, where each parent contributes one chromosome to each pair, resulting in a total of 46 chromosomes in most human cells.

This number includes 22 pairs of autosomes and 1 pair of sex chromosomes, determining an individual's sex (XX for females and XY for males).

NOTE: DON'T BE CONFUSED about the pair and number of Chromosomes in the Human body

Total Chromosomes: 46

Pairs of Chromosomes: 23

Explanation

Aqua is a greenish-blue color, often thought of as the shade of water.

Aqua, water in Latin, is a variation of cyan that sits between green and blue in the color wheel.

Aqua means پانی

Water means پانی

Explanation

Decomposition is slow in deserts due to low moisture and extreme temperatures.

Lack of water limits microbial activity, reducing the breakdown of organic matter.

Explanation

Oxyacetylene flame is used in welding and cutting metals due to its high temperature.

It provides a flame temperature of about 3200°C, making it suitable for industrial applications.

Explanation

The Earth moves in two primary motions: Rotation (spinning on its axis) and Revolution (orbiting around the Sun).

Rotation causes day and night, while revolution leads to seasons.

Explanation

The three types of pollution are:

• Air Pollution: Harmful substances released into the air, like carbon monoxide and sulfur dioxide.
• Water Pollution: Contamination of water sources with pollutants such as industrial waste and sewage.
• Land Pollution: Degradation of land through activities like deforestation and improper waste disposal.

Explanation

Explanation

An ocean current is a continuous, directed movement of seawater.

Ocean current is generated by:

• A number of forces acting upon the water including wind
• The Coriolis effect
• Breaking waves
• Cabbeling
• Temperature and salinity differences.

Additional Information:

Ocean floods:

Coastal flooding occurs when dry and low-lying land is submerged (flooded) by seawater

Cyclone:

Cyclones are caused by atmospheric disturbances around a low-pressure area distinguished and often destructive air circulation.

Tsunami:

Tsunamis are giant waves caused by earthquakes or volcanic eruptions under the sea.

Explanation

Pressure formula is expressed as P = F/A,

• where P is pressure,
• F is force,
• and A is the area by which the force is applied perpendicularly.

Its SI unit of pressure is Pascal (represented as Pa) 

Definition of Pressure:

 Pressure can be defined as the force acting per unit area.
