The development of landforms on Earth comes from the interplay between internal and external forces. Internal forces, like tectonic activity and volcanic eruptions, originate from within the Earth, while external forces such as erosion and sedimentation operate on the Earth's surface. Imagine a hilly area formed by significant tectonic movement that starts experiencing wear from wind and water. What long-term effects could this combination of forces have on the landscape of the area?

Terrestrial landscapes are shaped by a variety of geomorphological processes, which can be broadly categorised into endogenous and exogenous. Endogenous factors, like tectonism and volcanism, operate from within the Earth, while exogenous factors, such as erosion and sedimentation, come from outside. Let's think about a mountainous area that has recently experienced heavy rainfall and landslides. Which of the geomorphological processes, endogenous or exogenous, has had a more immediate effect on the landscape changes in this area and why?

After World War II, the establishment of the United Nations (UN) was a major turning point in efforts to foster global cooperation and prevent large-scale conflicts. Besides its role in maintaining peace and security, the UN engages in multiple areas like human rights, sustainable development, and humanitarian aid. Picture a situation where the UN must step in during an armed conflict that jeopardises regional stability and triggers a humanitarian emergency. What is the key challenge the UN faces in balancing the sovereignty of countries with the necessity for humanitarian intervention, and how does this situation impact the organisation’s effectiveness in fulfilling its global responsibilities?
