The correct answer is: B. Hypabyssal rocks.
Hypabyssal rocks are igneous rocks that form when magma cools and solidifies at a relatively shallow depth from the Earth’s surface. They are typically found in intrusions, such as dykes and sills, and are less common than volcanic rocks.
Plutonic rocks are igneous rocks that form when magma cools and solidifies at great depths within the Earth’s crust. They are typically coarse-grained and have a wide range of compositions.
Volcanic rocks are igneous rocks that form when magma or lava erupts onto the Earth’s surface. They are typically fine-grained and have a wide range of compositions.
Igneous rocks are rocks that are formed when magma or lava cools and solidifies. Magma is molten rock that is found beneath the Earth’s surface. Lava is magma that has reached the Earth’s surface. Igneous rocks can be classified into three types: intrusive, extrusive, and hypabyssal.
Intrusive igneous rocks form when magma cools and solidifies beneath the Earth’s surface. They are typically coarse-grained because they have time to cool slowly. Examples of intrusive igneous rocks include granite, gabbro, and diorite.
Extrusive igneous rocks form when lava cools and solidifies on the Earth’s surface. They are typically fine-grained because they cool quickly. Examples of extrusive igneous rocks include basalt, rhyolite, and andesite.
Hypabyssal igneous rocks form when magma cools and solidifies at a relatively shallow depth beneath the Earth’s surface. They are typically intermediate in grain size between intrusive and extrusive igneous rocks. Examples of hypabyssal igneous rocks include dolerite, gabbro, and diorite.
