Lava is a hot liquid from the inside of the earth and ash is a lava powder, which is very hot.
An ash fall is a rain of airborne ash resulting from a volcanic eruption.
People in a volcano zone need to be removed until the ash and lava have finished coming out of the volcano. Homes and businesses need to be evacuated and cars are moved out of the way. The volcano will need to be done erupting before people are allowed back into the area.
because it has lots of minerals from the rock in it.

No. Volcanoes have vents. Vents are holes though which ash, gas, and lava can erupt.
No. While volcanic ash can have a basaltic composition, it usually does not. Basalt forms from lava. Volcanic ash forms tuff.
volcanic ash, volcano bombs, and lava
Solidified lava, sulphur, volcanic ash.
A layer of ash and lava is a geologic feature formed by the deposition of volcanic ash and solidified lava during volcanic eruptions. These layers can build up over time to create thick sequences of volcanic material, which can be preserved in the rock record as distinct stratigraphic units.
Lava landforms are created by the eruption and cooling of molten lava on the Earth's surface, forming features like lava flows, lava domes, and lava tubes. Ash landforms are the result of volcanic eruptions that produce ash and volcanic debris, creating features like cinder cones, ash clouds, and pyroclastic flows. Magma landforms are underground structures formed by the cooling and solidification of magma, such as plutons, batholiths, and dikes.
True. Lava flows and volcanic ash are indeed examples of magma that has reached the earth's surface during a volcanic eruption.

Volcanic landforms and features.
Cinder, cooled lava, and ash
Acid lava cones are smaller and much steeper than ash/cinder cones. Acid lava cones are almost convex in shape and are formed due to thick lava that does not flow freely and cools before reaching very far. This gives in the conical 'dumpy' shape. While ash and cinder cones are more symmetrical and concave in shape. They are formed due to volcanic lava or volcanic bombs (of solidified lava) that was shot up in the air, cool and hardened and broke up into tiny pieces (of ash or cinders) before coming back down to the earth's surface.
The volcanic ash burst and formed a huge cloud.
Volcanic ash is magnetic because the ash has iron in in the objects the lava/magma burns. Or the ash already has iron from the mantle of the Earth burning into the magma of the core.
