Answer:
A. Tsunamis:
Tsunamis usually cause the greatest amount of destruction in comparison to other waves. There are massive waves that can cause the destruction of most ecosystems.
Explanation:
- Tsunamis cause large displacement of the water bodies and are generally known as the killer waves.
- The tidal waves are a regular recurrent shallow body of water and affect the gravitational attraction between the sun and the Sun, Moon and the earth and maybe often referred to as tsunami but do not generate to the small tidal waves
- The wind-driven waves or the surface waves are those created by the formation of the surface water and them tens to blow away the occurs for the Oceana and are found across the open seas and globally across the coast. As compared to the tsunami that is tectonically produced these are due to the disturbance in the body of the water.

Answer:
Africa's physical geography, environment and resources, and human geography can be considered separately. Africa has eight major physical regions: the Sahara, the Sahel, the Ethiopian Highlands, the savanna, the Swahili Coast, the rain forest, the African Great Lakes, and Southern Africa
Explanation:
Lava flows are the least hazardous of all processes in volcanic eruptions. How far a lava flow travels depends on the flows temperature, silica content, extrusion rate, and slope of the land. A cold lava flow will not travel far and neither will one that has a high silica content. Such a flow would have a high viscosity<span> (a high resistance to flow). A basalt flow like those in Hawai'i have low silica contents and low viscosities so they can flow long distances. Such a flow can move as far away as 4 km from its source and have a thickness of 10 m (Bryant, 1991). These flows can move at rates of several kilometers per hour (Scott, 1989). </span><span>More silica-rich flows can move as far away as 1.3 km from their sources and have thicknesses of 100 m (Bryant, 1991). These flows can move at rates of a few to hundreds of meters per hour (Scott, 1989). If a lava flow is channelized or travels underground in a lava tube then the distance it travels is greatly extended.</span>
