Geography: An Integrated Approach
When lava and other materials reach the surface they are called extrusive. The
resulting landforms vary in size from tiny cones to widespread lava flows.
Materials injected into the crust are referred to as intrusive. These may later be
exposed ...

Science of Earth Systems
The opposite of intrusive rock is extrusive rock, which forms when lava cools on
the Earth's surface (Figure 10-6). Igneous rocks are identified by their texture,
color, density, and mineral composition. The texture of a rock is influenced by the

Physical Geology of High-level Magmatic Systems
When the dome became extrusive, rock falls and probably also block-and-ash
flows formed. The evolution of the Donnersberg intrusive-extrusive dome, thus
deduced, has been used as an example for these schematic diagrams.

The Basics of Earth Science
Extrusive rocks are also the result of volcanic activity, but they result when
magma is cooled rapidly and is extruded onto the surface during volcanic fissure
eruptions. The magma that comes to the surface and flows is called "lava."
