Which intrusion feature maystart as a sill butas more magna builds it pushes upward lika a lens?
A laccolith intrusion feature may start as a sill, where magma is injected parallel to the rock layers. As more magma accumulates, it can create a bulge that pushes the overlying layers upward, creating a dome-shaped structure resembling a lens. This process is characteristic of the formation of laccoliths in geology.

Earth science define cross cutting?
Sometimes magma pushes, or intrudes, into cracks in existing rocks. When the melted rock cools and solidifies, the resulting feature is called an igneous intrusion. This image shows metamorphic rock in Death Valley, California, cut by a darker igneous intrusion. The principle of cross-cutting relationships states that an igneous intrusion is always younger than the rock it cuts across.
What is a Lacolith?
A lacolith is a type of igneous intrusion where magma pushes up the overlying rock layers without actually breaking through the surface. This creates a dome-like structure with a flat base and a rounded top. Lacoliths are typically found in mountainous regions and are associated with the formation of volcanic or plutonic rocks.
How can you tell the difference between an intrusion and extrusion if there is a layer of sandstone on top?
An intrusion is formed when magma pushes into surrounding rock layers, creating intrusive features like veins or sills, which would be visible beneath the layer of sandstone. In contrast, an extrusion occurs when magma is ejected onto the surface as lava, forming extrusive features like lava flows or volcanic cones above the sandstone layer. The presence of different types of volcanic features would help distinguish between an intrusion and an extrusion in this scenario.
What landform can a glacier build up?
A glacier builds up a moraine in front of it as it pushes dirt and rock ahead of it.
Is pikes peak a folded mountain?
I think it is a dome mountain, formed when magma pushes its way up under the Earth's surface. The melted rock forms a bulge that creates a mountain.
Which intrusive feature may start as a sill but as more magma builds it pushes upward like a lens?
A laccolith is an intrusive feature that may start as a sill but as more magma accumulates, it can cause the overlying rocks to bend and create a dome-like shape. Over time, this dome can grow larger and form a lens-shaped intrusion beneath the Earth's surface.
Why do tears come out?
because your emotion builds up a pushes it out i guess
What happensin a volcanic eruption?
pressure builds up in the earth and pushes the magma up to the surface.

What is a vertical intrusion called?
A vertical intrusion is called a "dike." Dikes are geological formations that occur when magma pushes through existing rock layers and solidifies, creating a vertical wall of igneous rock. They are typically formed in a variety of environments, often associated with volcanic activity.

This creates a dome-like structure with a flat base and a rounded top. Lacoliths are typically found in mountainous regions and are associated with the formation of volcanic or plutonic rocks.
This forms when magma pushes into vertical cracks and cuts through layers of rock?
This forms a volcanic feature called a dike. Dikes are vertical or near-vertical intrusions of magma that cut across existing rock layers. They are a type of igneous intrusion that forms when magma forces its way into fractures in the surrounding rock.
How is the airplane flies?
High air pressure builds up under the wings, and low air pressure goes over the wing, and that makes lift. Thrust from engine pushes it forward.
How are rocks made?
When pressure pushes down on sediment, the sediment turn solid because they have sat aside for a long time and the pressure builds up to form a rock.

Is there a relationship between plate tectonics and volacnoes?
The movement of plates cause volcanoes pressure builds in the mantle when 2 plates push towards together and the pressure pushes lava up through the ground and over time this makes volcanoes
What trouble does Percy get into on the field trip?
Percy made a bus explode with a Revolutionary War cannon and there was the whole "math teacher from Hades" thing.
