A. Community
B. Ecosystem
C. Population
D. Habitat
Check answer and explanation
Answer: Habitat
Explanation A habitat is the specific place where an organism lives and reproduces. It provides the food, water, shelter, and conditions necessary for survival.
Explanation Relative Humidity Depends on temperature, weather, and location ** Humidity in the air was measured by a Hygrometer *** Concept Of Humidity: Important Information: Please read Carefully Humidity is the presence of water vapor in the atmosphere. The higher the rate of temperatures, weather, and (hot) place tend to be the more water vapor rises into the air, and the more humidity that area is. The lower the rate of temperatures, weather, and (cold) places tend to be the less water vapor rises into the air, and the less humidity that area is. **
Explanation The temperature of the central part of the earth called core The core is the center of the earth and is made up of two parts: the liquid outer core and solid inner core. The outer core is made of nickel, iron , and molten rock. Temperatures here can reach up to 50,000 C. ND17-7-2023
Explanation Radiant energy is the energy of electromagnetic waves. It is a form of energy that can travel through space. For example, we receive the heat from the sun, which is located very far from the earth via radiation. The sun's heat is not transmitted through any solid medium, but through a vacuum. They are short waves .
جب بادل سرد علاقوں سے گزرتے ہیں تو وہ بارش یا برف میں بدل جاتے ہیں۔ اس عمل کو کیا کہتے ہیں؟
A. Evaporation
B. Transpiration
C. None of these
D. Condensation
Check answer and explanation
Answer: Condensation

A. Community
B. Population
C. Habitat
D. Ecosystem
Check answer and explanation
Answer: Ecosystem
Explanation An ecosystem includes all the living components (biotic factors) like plants, animals, and microorganisms , and non-living components (abiotic factors). Like soil, water, air, and sunlight , interacting with each other.
Explanation The sun's energy, called solar radiation, isn't equally distributed across the globe because of Earth's spherical shape . This “ unequal helping ” of solar radiation across our planet is effectively what causes weather and climate.
Explanation Tectonic Plates Movement (Most Common): The Earth's crust is broken into large tectonic plates that constantly shift. Volcanic Activities: Movement of magma beneath volcanoes can cause shifts and trigger earthquakes. Tectonic Dislocation (Faults): This refers to the actual fractures (faults) in the crust where plates slide past each other, which is the direct mechanism for most plate-related earthquakes. Other Causes: Human activities (mining, large reservoirs) and even large collapses of rock can also cause minor seismic events.
