Intrusive activity is when magma in the mantle or crust starts to cool and crystallize. Igneous rock forms from the crystallization.

Lahars are not examples of intrusive activity. Lahars are fast-flowing mixtures of water, rock debris, and volcanic ash that move down the slopes of a volcano during an eruption or due to melting snow and ice. Intrusive activities include the formation of sills, dikes, laccoliths, and batholiths, which involve the movement of magma into Earth's crust.
Sills, dikes, and volcanic necks are not examples of an intrusive igneous body. These features are formed by igneous activity in the Earth's crust but are not considered intrusive bodies because they are typically narrow and tabular in shape, rather than larger and more massive like intrusive bodies such as batholiths or plutons.
Volcanic eruptions at Earth's surface, known as extrusive activity, occur when magma escapes to the surface, resulting in lava flows, ash clouds, and pyroclastic flows. This activity typically forms features like volcanoes and lava plateaus. In contrast, intrusive volcanic activity occurs when magma cools and solidifies beneath the Earth's surface, creating igneous rock formations and structures such as batholiths and sills. While extrusive eruptions are often explosive and can rapidly alter landscapes, intrusive activity is generally slower and less visible but plays a crucial role in shaping the Earth's crust over time.
Magma can be either extrusive or intrusive. Extrusive magma forms on the Earth's surface during volcanic eruptions, while intrusive magma forms below the surface and cools slowly to create intrusive igneous rocks.
No. Lahars are the result of extrusive activity.
both form from heat-volcanic activity

there was volcanic activity in the area at some point in the past

What is the difference between intrusive and intrusive.
Volcanic eruptions at Earth's surface, known as extrusive activity, occur when magma escapes to the surface, resulting in lava flows, ash clouds, and pyroclastic flows. This activity typically forms features like volcanoes and lava plateaus. In contrast, intrusive volcanic activity occurs when magma cools and solidifies beneath the Earth's surface, creating igneous rock formations and structures such as batholiths and sills. While extrusive eruptions are often explosive and can rapidly alter landscapes, intrusive activity is generally slower and less visible but plays a crucial role in shaping the Earth's crust over time.
Intrusive rocks have large crystals due to slow cooling beneath the Earth's surface, giving them a coarse texture. They often appear in large, plutonic formations such as batholiths or stocks. Intrusive rocks generally show no evidence of volcanic activity.
