Answer: B. Metamorphic rocks
Explanation: Metamorphic rocks are those that have undergone changes due to extreme heat and pressure. Thus, the rock, from which it becomes a metamorphic rock, is heated at temperatures above 150-200 ° and exposed to a pressure of 1500 bar. In this way, the structure of the rock is changed, in terms of the arrangement of the atoms, and the result is a change of physical and chemical properties. There are two basic types of metamorphic rocks: foliated and slate. Generally, some of the metamorphic rocks are anthracite, schist, quartzite, marble, etc.

Answer:
extrusive rocks.
Explanation:
When an igneous rock contains large crystals of minerals surrounded by the fine grained or glassy material (set in a matrix of glassy part).The texture is known as Porphyritic texture and the large crystals are known as Phenocrystals and the fine grained or glassy part is called as Ground mass.
When this Porphyritic texture showing igneous rocks are known as Porphyrites. The texture is largely found in volcanic and hypabassal rocks so these rocks are the extrusive rocks.
Answer:
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
Explanation:
Sea drilling cores are one way to get samples that can be used for analysis whereby some information such as type of sediment on the seafloor and type of rock on the seafloor can be known. Surface samplers can be collected from sediment at very top layers or inside deep of the ocean floor. These samples could have animals hidden, , water and some particles that can be analysed in the muddy deep, devices such as Coring devices can be used in collection of cores. The information that can be determined directly by analyzing seafloor drill cores are;
✓The type of sediment on the seafloor.
✓The type of rock on the seafloor.
✓The rate of sediment deposition.
