Answer and Explanation:
- Volcanic activity occurs above places in the Earth where pressure, temperature, and the presence of water conspire to melt rock. There are two main ways Earth materials melt: 1) hot mantle rises and decompresses; and 2) water flows through hot rock. The first type of melting occurs at diverging plate boundaries (mid-ocean ridges; continental rift zones) and hotspots, where mantle beneath plates is hot but remains solid because it is under great pressure. As the hot mantle rises, sudden drop in pressure causes melting, much as taking the lid off a pressure cooker causes super-heated water to flash to steam. The second mechanism results in volcanism at convergent plate boundaries. As one plate dives (subducts) beneath the other, it heats up and releases hot fluids (similar to the way we sweat when we get hot). The fluids (mostly water) rise, wetting hot rock in their path and causing some of the rock to melt.
- Two types of Plate boundaries are often associated with volcanic eruptions:
> Plates rip apart at a divergent plate boundary, causing volcanic activity and shallow earthquakes;
> At a convergent plate boundary, one plate dives or “subducts” beneath the other, resulting in a variety of earthquakes and a line of volcanoes on the overriding plate.

Explanation:
geographer in general view their subject in four key concepts which speak to the nature of geography.Discuss geographical space
Geographical space refers to the physical and abstract dimensions of the Earth's surface, encompassing the distribution of phenomena, the relationships between places, and the spatial patterns and processes that shape our understanding of the world.
Geographers view their subject through four key concepts, one of which is geographical space.
Definition: Geographical space refers to the physical and conceptual dimensions of the Earth's surface. It encompasses the area, extent, and organization of features and phenomena across the Earth's surface.Physical dimension: Geographical space includes the physical attributes of the Earth's surface, such as landforms, climate, vegetation, and natural resources. These physical elements contribute to the diversity and variability of spatial patterns observed across different regions.Conceptual dimension: Geographical space also involves the conceptual understanding of space, including the ideas, perceptions, and cultural meanings that people associate with specific locations. This dimension considers how societies and individuals perceive, interpret, and assign values to different spaces.Spatial relationships: Geographical space emphasizes the spatial relationships between different places and the interactions that occur within and between them. It examines the connections, flows, and interdependencies that shape patterns of human activity, environmental processes, and the distribution of resources and power.By studying geographical space, geographers gain insights into how the physical and conceptual aspects of space influence human and environmental dynamics, providing a framework to understand the spatial patterns and processes that shape our world.
