Answer 1

Answer:

Metamorphic rocks become sedimentary rocks due to process of weathering and erosion.  

Explanation:

Metamorphic rock erodes on the surface and turns into sediment. The sediment forms layers. Each year new top layer forms. The earliest formed sediment gets compacted and cemented as the top layers get heavier. Forming sedimentary rocks in the process.

Answer 2

Answer:

1) heat

2) pressure

erosion

3) chemically active fluids

weathering

Explanation:

There are some environmental factors which changes metamorphic rocks into sedimentary rocks. The factors are heat, pressure, temperature, water and chemically active fluids etc. Chemically active fluids speed up the process of weathering. Water goes in the pore of rocks and when the temperature increases, the water molecule expand which make cracks in the rocks and weathering occurs.
