Fossils are formed in sedimentary rock because the rock is formed at temperatures that do not destroy the fossils like the igneous rocks would.

No, fossils are typically found in sedimentary rocks, not igneous rocks. Sedimentary rocks form from the accumulation and compaction of sediments, which can preserve fossils, while igneous rocks form from the cooling and solidification of molten rock, where fossils are usually destroyed.
Fossils are unlikely to be found in igneous rock because igneous rock forms through the cooling and solidification of molten rock, which destroys any fossils that may have been present. Most fossils are found in sedimentary rock layers where the remains of plants and animals can be preserved over time.
because sedimentary rocks are on the top layer, while igneous rocks are were the magma is
Igneous rocks and most metamorphic rocks, of an igneous origin.
Igneous rock is formed by the cooling of magma - liquid or molten rock. Fossils won't be found in there for obvious reasons. We don't even bother to look for fossils in something like, say, basalt, which is an igneous rock. A link is provided to the Wikipedia article on igneous rock.
Igneous rocks are formed from cooling and solidifying of molten rock, so they usually do not contain fossils. This is because fossils are typically found in sedimentary rocks, which form from the accumulation of sediment and organic materials, preserving the remains of plants and animals.
No, in fact plenty of fossils are found in sedementary rocks.
Randomly arranged interlocking crystals and no fossils :)
