place the first event at the top and the last at the bottom.

• magma forms in the mantle
• magma rises through the crust
• pressure builds up
• eruption occurs
• magma reaches the surface
• lava flows out
• a volcanic cone forms
• layers of lava and ash build up

Explanation:

This is a sequence of volcanic formation events. The process starts with magma forming deep in the mantle, then rising toward the crust. As magma rises, pressure accumulates until it forces an eruption. Magma reaches the surface during the eruption, becoming lava that flows out. Over time, repeated lava and ash deposits build up, eventually forming a volcanic cone.

Answer:

1. magma forms in the mantle
2. magma rises through the crust
3. pressure builds up
4. eruption occurs
5. magma reaches the surface
6. lava flows out
7. layers of lava and ash build up
8. a volcanic cone forms
