Metamorphic Rock Statements Analysis

This question asks to evaluate two statements about metamorphic rocks. Let's analyze each statement:

Statement 1: Ortho-metamorphic Rocks Origin

Statement 1 claims that "Ortho-metamorphic rocks are formed from igneous rocks."

The term 'ortho-' in metamorphic petrology indicates that the parent rock (protolith) was an igneous rock.
Therefore, ortho-metamorphic rocks are indeed metamorphic rocks derived from igneous precursors.
Statement 1 is correct.

Statement 2: Heat Metamorphism Identification

Statement 2 claims that "Intense heat of the intruding magmas results in metamorphism of the surrounding rocks, a process known as dynamic metamorphism."

Metamorphism caused by the heat radiating from intruding magma bodies is specifically called contact metamorphism or thermal metamorphism.
Dynamic metamorphism, conversely, is caused by mechanical stresses and deformation, typically occurring along fault zones.
Statement 2 incorrectly equates heat-driven metamorphism with dynamic metamorphism.
Statement 2 is incorrect.

Conclusion on Statements

Based on the analysis:

Statement 1 is correct.
Statement 2 is incorrect.

Therefore, only statement 1 is correct.

Important Questions from Rocks and Soils

Soil, in which nearly all our food grows, is a living resource that takes years to form. Yet it can vanish in minutes. Each year 75 billion tonnes of fertile soil is lost to erosion. That is alarming — and not just for food producers. Soil can trap huge quantities of carbon dioxide in the form of organic carbon and prevent it from escaping into the atmosphere.
On the basis of the above passage, the following assumptions have been made :
1. Large scale soil erosion is a major reason for widespread food insecurity in the world.
2. Soil erosion is mainly anthropogenic.
3. Sustainable management of soils helps in combating climate change.
Which of the above assumptions is/are valid ?
