MAHA TET Paper 1: Environmental Studies Test - 5 - MAHA TET MCQ

To calculate the average speed of the person, we can use the formula:

Average Speed=Total Distance Traveled/ Total Time Taken

Given Data:

1. Initial odometer reading = 1233 km
2. Final odometer reading = 1581.5 km
3. Total time taken = 8.5 hours

Step 1: Calculate the Total Distance Traveled

Total Distance = Final Reading−Initial Reading

Total Distance = 1581.5 km−1233 km=348.5 km

Step 2: Calculate the Average Speed

Average Speed = 348.5 km/ 8.5 hour {km/hr}

Average Speed = 41km/hr

Answer:

The correct answer is: c) 41 km/hr

Concept:

• Cow dung and cow urine are considered holy in India.
• Applying cow dung is part of the cleaning process in Indian villages.
• In festivals also, after cleaning their houses, rural people apply the cow-dung paste on walls and floors.
• It is just like how urban people make their houses painted for getting a festive feel.

Explanation:

• Cow dung has a very unpleasant smell.
• However, when mixed with water and mud the smell becomes un-noticeable to people.
• Insects on the other hand can still get the unpleasant smell of cow dung.
• As a result, the insects keep away from such places.
• Cow dung is also used to make houses water-resistant and work as an insulator.

The family members coat the floor of their room with a mixture of dung and mud every morning to prevent insects from entering the house.

Anjali should ask the students from different cultures and regions to bring food from home. They can display it, and each one of them can share the information with the other classmates. If the students are given the food to taste, it might have a long-lasting impression and learning on the student's mind. If the students bring the food, it would be easier for them and their classmates to ask questions from each other and various other information about the food.
Hence, the correct answer is "Ask students from different cultures/regions to bring food from home, display it and share the information with classmates".

• Mountaineering is a much demanding adventurous activity.
• It is sought after by people who are willing to undergo extensive physical training and have strong willpower.

Difficulties faced:

• The climate at higher elevations is not the same as at sea level, and hence the mountaineers face the following difficulty:
  • Lack of oxygen.
  • Low atmospheric pressure.
  • Very low freezing/sub-freezing temperatures.
  • Very high chilly winds.
• Other than climatic factors, the topography adds another difficulty to the climbers as:
  •  At the high mountain, slopes are steep and walking becomes difficult.
  • Snow on the mountain makes it slippery.
  • Avalanches, landslides are common in the mountains.

The Deccan Plateau is a plateau in India which covers the maximum part of the southern part of India.

Asking probing and imaginative questions create curiosity in the minds of the students due to which children make efforts to find the answers by themselves, or they think about the different and alternative answers.
