The material on the surface of the moon is similar to 'basalt' or 'granite'?
basalt
What is basalt's luster?
Luster means that something has a shiny or glossy surface. Basalt is a rock that does not have a luster at all.
Is Basalt intrusive or extrusive?
extrusive it forms when lava from a volcanic eruption cools on the surface.
What is Vesicular Basalt?
Vesicular basalt has empty bubble-shaped holes, but were once filled with gas. These holes, called vesicles, form during the extrusion of magma to the surface.
Is basalt mountain a volcano in basalt Colorado?
Yes, Basalt Mountain is an ancient shield volcano and is no longer active. The cliffs facing town are evidence of a post-tertiary age collapse of the dome and expose the many layered flows indicative of shield volcanos.
How can you tell that sandstone is older than a basalt layer?
If the sandstone is below the basalt layer, it is older. Though caution is advised, to make sure it is really a basalt layer and not an intrusion of gabbro. Other indicators that the sandstone is older is evidence of alteration to the sandstone where the two meet (called a "baked contact") and pieces of sandstone being found in the the basalt.
What type of area granite and basalt rocks found in?
Principally and respectively they are the main continental and oceanic crust rocks of the Earth. They will also appear on the surface as igneous rocks by intrusion or extrusion (volcanism).
The material on the surface of the moon is similar to 'basalt' or 'granite'?
basalt
What is basalt's luster?
Luster means that something has a shiny or glossy surface. Basalt is a rock that does not have a luster at all.
Does igneous basalt form partly as the result of surface processes?
Yes. In that basalt is formed from rapid cooling of lava at or near the surface.
Is Basalt intrusive or extrusive?
extrusive it forms when lava from a volcanic eruption cools on the surface.
Why is basalt classified as an igneous rock?
Basalt is considered igneous because it forms when mafic lava cools at Earth's surface.
Why does basalt cool fast?
Basalt cools fast because it is at the surface, where air carries heat away rather quickly.
Which features may occur when volcano lava cools at the surface?
Basalt Plateau
What forms when molten material from beneath Earth's surface cools and hardens?
Basalt
What is a Igneous rock that forms from lava on Earth's surface?
A type of igneous rock that forms from lava on Earth's surface is called basalt. Basalt is a dark-colored rock that is often found in volcanic regions and has a fine-grained texture. It is commonly used in construction, as it is durable and has good resistance to weathering.
Dark regions on the surface of the moon are generally?
Dark regions on the surface of the moon are generally basalt flows. Basalt is a dark rock. The flows have been caused by rock melting due to heat generated by meteor impacts.
