At diverging platediverging plateIn plate tectonics, a divergent boundary or divergent plate boundary (also known as a constructive boundary or an extensional boundary) is a linear feature that exists between two tectonic plates that are moving away from each other.https://en.wikipedia.org › wiki › Divergent_boundaryDivergent boundary - Wikipedia boundaries, earthquakes occur as the plates pull away from each other. Volcanoes also form as magma rises upward from the underlying mantle along the gap between the two plates.
Where do tectonic activities such as earthquakes or volcanic eruptions tend to occur?
The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire.
How volcanoes and mountains are created?
Volcanoes are mountains but they are very different from other mountains; they are not formed by folding and crumpling or by uplift and erosion. Instead, volcanoes are built by the accumulation of their own eruptive products -- lava, bombs (crusted over ash flows, and tephra (airborne ash and dust).

What causes the creation of volcanoes and eruptions?
The melted rock, or magma, is lighter than the surrounding rock and rises up. This magma collects in magma chambers, but it is still miles below the surface. When enough magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
What builds up causing volcanoes to erupt?
If magma is thick and sticky, gases cannot escape easily. Pressure builds up until the gases escape violently and explode.
How are volcano and mountains formed?
Volcanic mountains form when molten rock from deep inside the Earth erupts through the crust and piles up on itself. The islands of Hawaii were formed by undersea volcanoes, and the islands seen above water today are the remaining volcano tops. Well-known volcanoes on land include Mount St.

Why do mountains volcanoes and earthquakes occur at certain spots?
Certain features of Earth occur at each of the three types of boundaries. These features move because of movement at plates at the plate boundaries. Mountain ranges, ocean trenchesocean trenchesThe Mariana Trench or Marianas Trench is located in the western Pacific Ocean about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width.https://en.wikipedia.org › wiki › Mariana_TrenchMariana Trench - Wikipedia, volcanoes, and earthquakes occur in patterns. The movement of plates causes these features to occur.
What or how are volcanoes made or formed?
A volcano is formed when hot molten rock, ash and gases escape from an opening in the Earth's surface. The molten rock and ash solidify as they cool, forming the distinctive volcano shape shown here. As a volcano erupts, it spills lava that flows downslope. Hot ash and gases are thrown into the air.

Why do volcanoes happen in certain areas?
Volcanic eruptions occur only in certain places and do not occur randomly. This is because the Earth's crust is broken into a series of slabs known as tectonic plates. These plates are rigid, but they “float” on a hotter, softer layer in the Earth's interior.
How were the mountains formed?
Mountains form where two continental plates collide. Since both plates have a similar thickness and weight, neither one will sink under the other. Instead, they crumple and fold until the rocks are forced up to form a mountain range. As the plates continue to collide, mountains will get taller and taller.
