the igneous rock must be broke down or weathered down by erosion into sediments that then compact and cement together by pressure (and maybe heat- i cant remember whether or not) over the time period of many years
Heat, erosion and pressure.
Most of it you got right. Have you ever heard of something called the rock cycle? If you have, good. If you haven't, here is a link to an excellent diagram: http://www.emporia.edu/earthsci/student/henderson1/rock_cycle.gif Anyway, if you look at the diagram, you can see how igneous rock can transform into sediment, then sedimentary rock, or bypass sedimentary rock altogether and go to metamorphic rock. Sedimentary rock can turn into metamorphic rock with heat and pressure. However, to turn into igneous rock from sedimentary rock, it will have to melt down into magma/lava before becoming igneous rock once again.
Igneous rocks do not directly turn into shale. Shale is a sedimentary rock that forms from the compaction and cementation of fine-grained mud and clay particles. Igneous rocks can weather and erode to form sediment that eventually becomes shale through the process of lithification.
Intrusive igneous rock can turn into sedimentary rock through a process called weathering and erosion. Over time, the intrusive igneous rock is broken down into smaller pieces through physical and chemical weathering. These pieces are then transported and deposited as sediment, which can be lithified into sedimentary rock through compaction and cementation.
Metamorphic rock would probably have been the first rock type formed after the initial formation of the first igneous rock. Sedimentary rock formation relies on weathering and erosion, whereas metamorphic rock can be created by heat and pressure. It's likely that rock was metamorphosed before weathering existed .
It melts it

Sandstone is sedimentary itself.
No rock. Any rock can turn into sedimentary rock, such as granite (igneous rock) and slate (metamorphic rock). Even sedimentary rock can turn into other sedimentary rock.
no it can't
Melting.
Sedimentary rock melts, then it cools to form Igneous rock. Hoped this helped. :)
yes. it can turn into either one
Igneous rocks are formed when rock melts in a volcano or other hot spot.
Yes. In the rock cycle, any sedimentary rock can be transformed into a metamorphic rock due to deep burial where the rock is changed by the earth's high temperature and pressure, an exposure to a plutonic intrusion, where rocks such as granite are formed, or any other process where heat and pressure alter the composition, appearance, and classification of a rock. An igneous rock can turn into a metamorphic rock or a sedimentary rock. A metamorphic rock can turn into an igneous rock or a sedimentary rock, and a sedimentary rock can turn into an igneous rock or a metamorphic rock.
It melts then cools off
