What clue tells geologists intrusion?
A clue that tells geologists about an intrusion is the relationship between the rock layers. An intrusion is younger than the surrounding rocks it cuts through, so if the intrusion appears to cut across existing layers, it is likely an intrusion. Additionally, the mineral composition and texture of the intrusion can differ from the surrounding rocks, providing further evidence of an intrusion.
How do you know that an intrusion is younger than its surrounding rock layers?
An intrusion is younger than its surrounding rock layers if it cuts across them. This is because the intrusion must have been deposited after the surrounding layers were already in place. Additionally, any fossils or index minerals found in the intrusion would be younger than those in the surrounding rock layers, providing further evidence of relative age.
What is evidence that groundwater causes erosion and deposition?
Evidence of groundwater causing erosion and deposition includes the formation of sinkholes through the dissolution of underground rocks, the creation of caves and caverns from the movement of water through porous rock formations, and the deposition of minerals as groundwater emerges at the surface in springs or seeps. Groundwater can erode and deposit sediments as it flows through underground aquifers, shaping the landscape over time.
To search for underground water using a divining rod?
There is no scientific evidence to support the use of a divining rod for detecting underground water. It is considered a pseudoscience and relies on a phenomenon known as ideomotor response, where subconscious movements of the user's hand cause the rod to move. It is recommended to use more reliable methods such as ground-penetrating radar or consultation with hydrogeologists for locating underground water.
What evidence of the KT boundary in Colorado has been discovered by researchers?
Researchers have found evidence of the KT boundary in Colorado, including a layer of sediment containing high levels of iridium, shocked quartz, and microtektites. These materials are characteristic of the impact event that caused the mass extinction of the dinosaurs.
Which characteristic provides the best evidence that pegmatite is solidified deep underground?
Very coarse texture.
Which characteristic provides the best evidence that his pegmatite solidified deep underground?
Large crystal size is the best evidence that a pegmatite solidified deep underground. This is because slow cooling at depth allows sufficient time for minerals to grow into large crystals before solidification.

What provides evidence that geologic activity occurred in the past on Earth's Moon?
the presence of solidified lava flows on the Moon
Which of the following provides evidence that geologic activity occurred in the past on Earth's Moon?
the presence of the solidified lava flows on the moon
Which of the four words is not a characteristic of scientific method logic imagination bias evidence?
Imagination is not a characteristic of the scientific method. The scientific method relies on logic, evidence, and minimizing bias to form conclusions based on empirical observations and experimentation.

What evidence do you have the sun contains the element iron?
The spectral lines. Each element has a characteristic "fingerprint" in a spectrum.
Can a A stock London Underground train couple to a 1973 stock?
No, they are different heights. Visit Uxbridge for the evidence.
How do think scientists collected new evidence about deep oceans?
They go underground and see what there if it is deep they can use a submarine

Which characteristic provides the best evidence about the environment in which a rock was formed?
Mineral composition is a key characteristic that provides evidence about the environment in which a rock was formed. Different minerals form under specific temperature, pressure, and chemical conditions, offering valuable clues about the geological processes that shaped the rock.
