rising magma from the mantle puts a stress on the crust above it. match the answers below with an explanation to describe what happens when this occurs below continental crust?
instructions
mountain ranges form
volcanoes
ocean basins
earthquakes

Explanation:

• Mountain ranges: When tectonic forces (related to mantle activity including rising magma - induced stress) cause continental crust to collide or be compressed, mountain ranges form. The stress from rising magma can contribute to the tectonic movements that push crustal plates together, leading to the uplift and formation of mountain ranges.
• Volcanoes: Rising magma from the mantle can reach the surface through weak points in the continental crust. When magma erupts onto the surface, it forms volcanoes. The stress from the rising magma can create pathways (like fissures or vents) for the magma to escape and build up volcanic structures.
• Ocean basins: Ocean basins are mainly formed by processes related to oceanic crust (like seafloor spreading at mid - ocean ridges), but in the context of continental crust stress from mantle magma, if there is rifting of continental crust (due to mantle - related stress), it can lead to the formation of new ocean basins over time as the crust pulls apart and the area fills with water. However, this is a more long - term and large - scale process related to the interaction of mantle forces and crustal movement.
• Earthquakes: The stress on the continental crust from rising magma can cause the crustal rocks to break or slip along fault lines. This sudden release of energy due to the movement of the crust (triggered by the stress from mantle magma) results in earthquakes.

Answer:

• Mountain ranges: Matches with the process of crustal compression/uplift due to mantle - related stress (including from rising magma) leading to mountain formation.
• Volcanoes: Matches with rising magma reaching the surface and forming volcanic structures.
• Ocean basins: Matches with crustal rifting (due to mantle - induced stress) leading to the formation of ocean - filled basins (especially in the context of continental rifting).
• Earthquakes: Matches with stress - induced crustal movement and faulting.

(If we assume the top boxes are the "what happens" and the bottom are the causes/explanations as per the matching:

1. Mountain ranges (top) - Mountain ranges form (bottom)
2. Volcanoes (top) - Volcanoes (bottom) (since rising magma forms volcanoes)
3. Ocean basins (top) - Ocean basins (bottom) (due to crustal rifting from mantle stress)
4. Earthquakes (top) - Earthquakes (bottom) (due to stress - induced crustal movement))
