Question
What term describes the natural breakdown of rocks on
Earth's surface due to environmental factors?Solution
Weathering refers to the physical and chemical breakdown of rocks and minerals at the Earth’s surface. Natural elements such as water, temperature fluctuations, and biological activity drive this process, leading to soil formation and landscape changes.
- What approximate value will come in place of the question mark (?) in the following question? (Note: You are not expected to calculate the exact value.)
What approximate value should come in the place of (?) in the following questions?
908.90 –190.32 + √? = 23.03 * 5.2 + 24.72
? = (7.11/2.12) + (10.88/4.09) + (45.12/11.98)
? = {29.7% of (97.72 × 40.04)} ÷ 3.92
(44.79 × 74.21) ÷ (11.862 – 33.12) + 37.48% of ? = 180.23
111.89 × 4.12 – 504.04 ÷ 2.12 = 170.12 + ?
√49 + 6.66% of 1725 + 22² = ?² - √361
[(√2024.85 ÷ 3.01) + (35.76 ÷ 11.92)]² × (3/4 of 39.99) = ?
(88.931% of 435) + (61.521% of 516) = ?
14.232 + 19.98% of 629.99 = ? × 6.99
