Does Stalactite have a hollow central tube?
Yes, stalactites can sometimes have a hollow central tube depending on how they formed. This can occur when water drips through the center of the stalactite, leaving behind the hollow tube as the mineral deposits accumulate on the outside.
What causes stalagmites?
Stalagmites are formed in caves when mineral-rich water drips from the ceiling and deposits minerals on the cave floor. Over time, these mineral deposits accumulate and harden into cone-like structures known as stalagmites.
What is a stalactite made from?
A stalactite is made of mineral deposits, typically calcium carbonate, that accumulate as water drips from the ceiling of a cave. Over time, these deposits form a cone-shaped structure that hangs down from the cave ceiling.
Are stalagmites made of limestone?
Yes, stalagmites are typically made of limestone. They form from mineral deposits left behind by dripping water in caves, which contain calcium carbonate. Over time, these deposits accumulate to form the stalagmites.
Are stalagmites cone shaped deposits?
Yes, stalagmites are cone-shaped mineral deposits that form on the floors of caves from dripping mineral-rich water. They grow upwards from the cave floor over time, typically made of minerals such as calcite or aragonite.
Is the following true or false lava flows on the moon sometimes overlap highlands showing that Maria deposits are younger than highlands?
True. Lava flows on the moon sometimes overlap highlands, indicating that Maria deposits are younger than the surrounding highlands. This overlapping occurs due to the volcanic activity that formed the lunar Maria after the formation of the surrounding highlands.
Do lava flows on the moon sometimes overlap highlands showing that maria deposits are younger than highlands?
Apollo 16 landed in the Descartes highlands to answer this very question. John Young and Charlie Duke were sent to Descartes to find signs of volcanic lava. They found none. Every rock they brought back was classified as a breccias. Apollo 15 landed close enough to Hadley Rille to sample its material. They found a few grains of volcanic material in samples collected near the rille. The photos they took of the rille and their own observations showed that the rille was a collapsed lava tube. Most lunar geologists believe that the lunar rilles are remnants of ancient lava flows. Although there is also evidence to support the fact that some rilles were formed when the subsurface solidified and the surface above sank to fill in the gaps. Some scientists also believe that some of the rilles formed when the moon cooled very rapidly. There are some areas of the moon where the maria is older than the highlands, but very little of it. For the most part, the maria is younger than the highlands. A very good source on this subject is the book "To A Rocky Moon" which can be downloaded as a PDF free from the Lunar Planetary Institute website. the first 17 chapters talk about how the Apollo landing sites were selected. Chapter 18 puts all the information together for you.
What is the most important mineral resource of the highlands?
The most important mineral resource of the highlands is often considered to be copper, particularly in regions like the Andes. This area is rich in copper deposits, which are crucial for electrical wiring and various industrial applications. Additionally, other minerals such as gold and silver are also significant, contributing to the economy and mining industries of highland countries. The extraction of these resources plays a vital role in local and national economies.
Ore deposits sometimes are found as a what?
extrusion
What has the author W J McMillan written?
W. J. McMillan has written: 'Geology and ore deposits of the Highland Valley camp' -- subject(s): Alkaline earth metals, Copper ores, Geology, Ore deposits
What are ore deposits sometimes found as?
layered intrusion.
Where do you find iron ore in new jersey?
Iron ore can be found in New Jersey in the form of magnetite and hematite deposits within the Highlands region of the state. These ore deposits were historically mined for iron production but are not commercially significant today.
Do all deposits gain interest?
Not all deposits gain interest. Deposits to a savings account in a bank usually earn interest. Security deposits sometimes earn interest depending on where you reside. Deposits into investments will earn interest and the rate depends on the state of the economy and the financial markets.
What is iliac arteries?
Iliac artery calcification is when there are calcium deposits forming. They form inside the artery and sometimes cause blockages. These calcifications form deposits in arteries.

When wind carrying sand slows down it sometimes deposits sediments to form what?
to form landforms
