Explore the forces shaping our landscapes, from constructive mountain building to destructive erosion and volcanic eruptions such as cinder cone, shield, and composite volcanoes. Learn about forces like deforestation and hot spots.
E N D
Number 1: What types of force is responsible for creating landforms?
Number 2: This is classified as a constructive force/action?
Number 3: A force that is responsible for changing (deforming) landforms.
Number 5: The process of completely clearing land of trees; it is a destructive force.
Number 6: Process by which wind, water, ice, or gravity transports soil and sediment from one location to another. The process of wearing away of rock into sediment.
Number 7: This is the breakdown of rock due to physical and chemical reactions.
Number 8: This explosive volcano is made entirely of pyroclastic materials; it has a narrow base and steep slopes.
Number 9: This volcano is a non-explosive volcano made from repeated layers of runny lava; it has very broad bases with gently sloping sides.
Number 10: This volcano is also called a stratovolcano; most common type of volcano that forms explosive eruptions of pyroclastic material followed by quieter flows of lava.
Number 11: This is a funnel-shaped pit that is found at the top of the central vent in most volcanoes.
Number 12: This is a volcanically active place on the Earth’s surface directly above a column of rising magma that is not a plate boundary. It creates a volcanic island, and often creates chains of volcanic islands such as Hawaii.
Number 13: This is an eruption that is rarer than a non-explosive eruption. It results in clouds of hot debris, ash, and gas being shot from a volcano.
Number 14: This eruption is very common and produces relatively calm flows of lava.
Number 15: This is the molten rock that erupts from volcanoes.
