Q.2.With reference to the Green Energy Open Access Portal in India, consider the following statements :
1. It has been launched by the Ministry of New and Renewable Energy (MNRE) to promote ease of access to renewable energy for commercial and industrial consumers,
2. The portal aims to facilitate transparency, reduce approval timelines, and ensure uniform procedures across states.
3. It allows consumers with a minimum contracted demand of 100 kW to apply for green energy access from any renewable source.

Q.1. What are the conditions that led to the distinction between terrestrial and Jovian planets in our solar system ?
1. The terrestrial planets were formed in the close vicinity of the parent star where it was too warm for gases to condense to solid particles while Jovian planets were formed at quite a distant location.
2. The solar wind was most intense nearer the sun; so, it blew off lots of gas and dust from the terrestrial planets and the solar winds were not all that intense to cause similar removal of gases from the Jovian planets.
3. The terrestrial planets are smaller and their higher gravity could not hold the escaping gases.

Q.2. In the context of Earth's early formation, which of the following best describes the process of differentiation ?
A. The breakdown of rocks on Earth's surface due to weathering and erosion.
B. Separation of heavier and lighter materials inside the Earth, forming layers like the crust, mantle, and core.
C. The large-scale movement of Earth's lithospheric plates over the asthenosphere, resulting in the drifting of continents over geological time.
D. The process by which compressional forces between converging tectonic plates result in the uplift and folding of the Earth's crust to form mountain ranges.

Q.3.Which of the following statements correctly explains the nature and behaviour of comets ?
1. Comets are made mainly of 'ices', that is ordinary water ice mixed with frozen gases such as methane, carbon dioxide and ammonia.
2. Comets develop a glowing tail when they approach the Sun as the heat causes frozen gases to condense from the comet's surface leading to a perceptible glowing tail.

Q.1. With reference to the evolution of Earth’s atmosphere and hydrosphere, consider the following statements :
1. The primordial atmosphere of Earth, mainly composed of hydrogen and helium, was lost due to solar wind activity.
2. The process of degassing released gases like water vapour and carbon dioxide from Earth's interior during its cooling phase.
3. Oceans were formed due to condensation of water vapour, and were established within 500 million years of Earth’s formation.
4. Substantial accumulation of oxygen in the atmosphere began only after oceans were saturated through photosynthesis.
