experiment about the green house effect

Magma forms by partial melting of upper mantle and crust. partial melt means that only a fraction of the available material forms a melt, and that the remainder stays solid. the partial melt rises because of its lower density and ascends through he crust. this is so conclusive mean the answer would be magma igneous rocks or balistic magma.

The most biodiversity is found on the ground, because here small plants, shrubs, big plants and trees grow, and when plants/trees die the branches/leaves are broken down by different insects and bugs which adds nutrients to the forest floor, therefore an area of great biodiversity.
