பௌதிக புவியியல் தேர்ச்சி 1-3 (க.பொ.த உயர்தரம்) அலகு பரீட்சை

The question is asking for the region where the temperature is higher, there is low pressure of air, and the presence of ozone layer is observed. The correct answer, "படை மண்டலம்" (Polar region), fits this description as it is known for its cold temperatures, low pressure, and the presence of the ozone layer.

The given options are all types of ecosystems. "உயிர்ககோளம்" refers to a terrestrial ecosystem, which includes living organisms such as plants, animals, and microorganisms that interact with each other and their environment on land. The other options, "வளிக்கோளம்" refers to a forest ecosystem, "நீர்க்கோளம்" refers to an aquatic ecosystem, and "கற்கோளம்" refers to a desert ecosystem. Therefore, the correct answer is "உயிர்ககோளம்" as it represents a type of ecosystem.

The correct answer is "கற்கோளம்" (Education). This is because education is the process of acquiring knowledge, skills, values, and attitudes through teaching, training, or research. It is a means of obtaining and imparting knowledge in various subjects and fields. The other options, உயிர்க்கோளம் (Breathing), வளிக்கோளம் (Weaving), and நீர்க்கோளம் (Water storage), do not accurately represent the process of obtaining knowledge and skills.

The correct answer is "திறந்த தொகுதியில்" which means "in an open space". This answer is chosen because it is the only option that specifically mentions an open space or an area that is not closed or restricted in any way. The other options either mention a closed space or a combination of open and closed spaces. Therefore, "திறந்த தொகுதியில்" is the most suitable answer.

The given answer is the correct sequence of the main sections of the atmosphere from bottom to top. The correct sequence is as follows: மாறன் மண்டலம் (troposphere), படை மண்டலம் (stratosphere), இடை மண்டலம் (mesosphere), வெப்ப மண்டலம் (thermosphere). This sequence represents the layers of the atmosphere based on their altitude, with the troposphere being the lowest layer and the thermosphere being the highest.

The correct answer is 3%. In the given question, we are asked to find the percentage of fresh water in the total water on Earth. Fresh water includes water in rivers, lakes, and groundwater, while saltwater is found in oceans and seas. It is estimated that only about 3% of the Earth's total water is fresh water, making it a scarce resource. Therefore, the correct answer is 3%.

In this question, the options provided are "இடைத்தரிப்பு" (translation: transition), "படைத்தரிப்பு" (translation: transformation), "மாறன் தரிப்பு" (translation: mutation), and "கொண்ராட்" (translation: fusion). The correct answer is "படைத்தரிப்பு" (transformation). The question is asking what is observed between the "படை மண்டலம்" (parental generation) and the "இடை மண்டலம்" (offspring generation). The term "படைத்தரிப்பு" refers to the process of transformation or change that occurs between generations.

The given answer states that reducing the temperature by 6.4 degrees Celsius for every 1000 meters of ascent from sea level is a decrease in temperature. This is because as one goes higher in altitude, the temperature tends to decrease. Therefore, the given answer correctly explains that the decrease in temperature is proportional to the increase in altitude.

The correct answer is "நீர்விழச்சி" which means "waterfall" in English. The other options mentioned are "கண்டத் திணிவு கள்" which means "volcanoes", "சமுத்திர படுக்கைகள்" which means "oceans", and "சமுத்திர அகழி" which means "tidal waves". Among these options, only "நீர்விழச்சி" refers to a type of landform that involves the flowing of water from a higher to a lower elevation, forming a waterfall.

The answer states that the interconnections in the lithosphere occur due to the movement and transformation of energy and matter. This suggests that the interactions between different components of the lithosphere, such as rocks, minerals, and fluids, result in the exchange of energy and the transformation of materials. This explanation highlights the role of energy and substances in shaping the connections within the lithosphere.

The given answer, "1386 கன மில்லியன் கீயூபிக் மீற்றர்", is the value of the total volume of water on Earth in cubic kilometers.

The correct answer states that conducting research in a controlled and systematic manner is necessary to study physical and social phenomena. This involves observing and analyzing physical and social phenomena in a structured and scientific way, taking into account the variables and factors that may affect the outcomes. By conducting research in a controlled and systematic manner, researchers can gather reliable and valid data, draw meaningful conclusions, and contribute to the advancement of knowledge in the field of science and social sciences.

The given question asks for the region in the atmosphere where there is a decrease in temperature with increasing altitude and where temperature is observed to be between 50-80 km above the Earth's surface. The correct answer is "இடை மண்டலம்" which translates to "Mesosphere" in English. The mesosphere is the layer of the atmosphere located between the stratosphere and the thermosphere. In this region, temperature decreases with increasing altitude due to the decreasing concentration of ozone and the low absorption of solar radiation.

In the given question, the options provided are "இனம்" (species), "அங்கி" (insect), "குடி" (ant), and "சு+ழல் தொகுதி" (reptile). The correct answer is "அங்கி" (insect) because it is the only option that represents a living creature that can be found in a specific place. The other options do not specify a particular living being.

The correct answer is "மெதேன், நைதரசன் ஒக்சைட், சல்பர் ஒக்சைட்". This is because in the given question, we are asked to show the order of the elements that are observed in the atmosphere. Methane (மெதேன்), Nitrogen (நைதரசன்), and Oxygen (சல்பர் ஒக்சைட்) are the gases that are commonly found in the Earth's atmosphere. Therefore, the correct order is Methane, Nitrogen, Oxygen.

The correct answer is "வட்டமுறை" which means "Circular method". This implies that the motion of the object follows a circular path. The other options mentioned, such as "நேர் கோட்டு முறை" (Straight line method), "மேற்படி இரு முறையிலும்" (Both straight line methods), and "மேற்படி முறைகளில் இல்லை" (No straight line methods), are incorrect as they do not accurately describe the nature of the motion.

The given answer states that the primary features of the சு+ழல்தொகுதி (compound letter) are உற்பத்தியாக்கி (consonant conjunct), பிரிகையாக்கி (vowel conjunct), நுகரி (nasalization), and சேதன/அசேதனப் பொருட்கள் (voiced/unvoiced consonants). These features are key components of the compound letter and are necessary to understand its pronunciation and usage.
