Explanation

• During nighttime, the air above the land loses heat and cools down, causing its density to increase.
• This is because cool air contracts and becomes denser than warm air.

Explanation

• Conduction is the transfer of internal energy (heat) through direct contact between particles or molecules.
• Including collisions and movements of electrons within a substance.
• This process occurs in solids.

Explanation

• Meteoroids are small particles from space that enter the Earth's atmosphere.
• It producing a bright streak of light, commonly known as a shooting star or meteor.
• If a meteoroid survives its passage through the atmosphere and lands on Earth, it is called a meteorite.

Explanation

• Navigation satellites, such as GPS (Global Positioning System), GLONASS, and Galileo.
• They are used to provide location information and precision timing signals to GPS receivers on the ground.
• It allowing for precise navigation and tracking of vehicles, ships, and aircraft.

Explanation

• GPS (Global Positioning System) is used for identifying the location of objects on Earth.
• GPS provides accurate positioning and timing information, enabling users to determine their precise location anywhere on Earth.
• GPS stands for Global Positioning System, a network of satellites orbiting the Earth.
• It provide location information and timing signals to GPS receivers on the ground.

Explanation

• Communication satellites are used for telecommunication.
• Including telephone communication, internet connectivity, and television broadcasting, enabling global communication networks.

Explanation

Weather satellites are used to provide weather forecasting and monitoring of weather patterns, climate change.

Explanation

Earth observation satellites are primarily used for observing the Earth's surface, atmosphere, and oceans.

Explanation

• ISA (Iranian Space Agency) was established in 2004.
• The Iranian Space Agency is responsible for the national space program of Iran.

Explanation

• ESA (European Space Agency) is an intergovernmental organization.
• It dedicated to the exploration of space, with 22 member states from Europe.
• It was established in 1975.
