Yes. Scoria is formed in lava fountains that occur during some volcanic eruptions.
Rocks with small crystals form above ground, because when formed under ground the magma makes the rock cool slower causing more time for the crystals to grow. Above ground the rock cools faster, because the air isn't as hot under ground than above ground.
No, not all volcanoes are found above ground. While many volcanoes form prominent mountains or hills, there are also underwater volcanoes, known as submarine volcanoes, which erupt beneath the ocean's surface. These underwater eruptions can create new landforms, such as islands, and contribute to the formation of mid-ocean ridges. Additionally, some volcanoes may exist as volcanic features on the ocean floor without ever breaking the surface.
Igneous rocks that cool above ground are called extrusive or volcanic rocks. Examples include basalt, andesite, and rhyolite. These rocks form when magma erupts onto the Earth's surface and cools rapidly.

Above the ground, Earth's features include mountains, valleys, plains, deserts, forests, rivers, lakes, and oceans. Below the ground, Earth's features include soil layers, groundwater, cave systems, mineral deposits, and the Earth's core composed of inner and outer core layers.
Lava forms underground in magma chambers. When it erupts onto the Earth's surface through volcanic activity, it becomes lava.

Plutonic rock is formed from magma in the Earth's crust. Volcanic rocks form from lava above ground.
A seamount is an undersea volcanic formation that does not rise at least 1000 meters above the surrounding sea floor. These features are common in ocean basins and can vary widely in size and shape, often forming as isolated peaks or smaller volcanic structures on the seabed.

An undersea volcanic formation that does not rise at least 1,000 meters above the surrounding sea floor is called a "seamount." Seamounts are typically formed by volcanic activity and can vary in shape and size. They are important features of the ocean floor, often supporting diverse marine ecosystems.

Additionally, some volcanoes may exist as volcanic features on the ocean floor without ever breaking the surface.
Magma rises to the surface through volcanic conduits and pathways called dikes, fractures, and conduits. This process is driven by buoyancy and pressure from the Earth's mantle. As magma moves upward, it can eventually erupt onto the surface as lava through volcanic vents or fissures.
