What is the landform that forms when rising magma, blocked by layers of rock, forces the layers of rock to bend upward?
A
volcanic neck
B
dike
C
lava plateau
D
dome mountain
Explanation: 

Detailed explanation-1: -Dome mountains are similar to volcanic mountains because they form by rising magma. As the magma rises, it lifts the rock above it into a dome shape on the surface. However, unlike a volcanic mountain, this magma never breaks through the surface to form a volcano.

Detailed explanation-2: -A laccolith is a dome shaped intrusive body that has intruded between layers of sedimentary rock. The rising magma forces the overlying layers to rise up into a dome.

Detailed explanation-3: -A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface. This molten rock is called magma when it is beneath the surface and lava when it erupts, or flows out, from a volcano.

Detailed explanation-4: -dikes-forms when magma forces itself across rock layers and hardens. 3. batholiths-When a large body of magma cools inside the crust, a mass of rock called a batholith forms. This forms the core of many mountain ranges.

Detailed explanation-5: -The magma produced is less dense than the surrounding rock, so it is forced slowly upward to Earth’s surface. If the magma reaches the surface, it can erupt as lava and ash. Layers of these materials can pile up over time to form volcanic mountains. form when lava and ash build up in one area over time.
