The small spaces between neurons where neurotransmitters are released are called alveoli?
The SYNAPSE is the very small space between two neurons and is an important site where communication between neurons occurs.
How are rocks and grains different?
rocks are formed from grains and grains are small and the rocks are big. Sedimentary rocks are formed when grains or sediments are compacted together.
Which rocks absorb water grainy rocks crystal rock?
when water is absorbed by rocks, and freezes, it will expand. therefore the rock will crack. Their bulk density increases (as the mass of the water contributes to the total mass of the rock) and the effective stress within the rock will decrease. This can ultimately cause the rock to fail without any increase in imposed loading.
What is an accessory mineral?
An accessory mineral is a mineral present in small amounts in a rock, but not considered to be characteristic of the rock.
Why can water pass easily through sandstone but not shale?
Because sandstone has wider particles than shale and this let's the water through.
What is the Difference Between Sandstone and Granite?
Sandstone, as its name implies, is composed of many small grains of sand loosely held together. You may be able to rub some off with your hand. The grains will be small and there will be spaces between the grains. Granite on the other hand is formed from the melt underground, and has crystallized there. The crystals will be larger - up to cm size - and firmly bound. [Except if the granite is badly weathered.]
What rock has large mineral grains?
Fine grains of rocks are referred to as "clasts." The word "clast" comes from the Greek word "klastos," meaning "broken."
Does basalt have small grains?
yes basalt has small grains
Does pumice have small grains?
No. Pumice does not have grains.
What do you call a phobia of small spaces?
A phobia of small spaces is called claustrophobia.
The small spaces between neurons where neurotransmitters are released are called alveoli?
The SYNAPSE is the very small space between two neurons and is an important site where communication between neurons occurs.
Explain the relatoinship between th density of a mineral and its size?
A mineral's density increases as its mass per unit volume increases. If a mineral has a small mass and large unit volume, its density is smaller. Whereas, if a mineral has a large mass and a small unit volume, its density is greater.
Granite have small or large grains?
Large grains, and crystals
Which rocks has two different size grains of the same mineral?
The rock is conglomerate. The other rock would be Breccia if its grains were not rounded.
There is space between atoms in a mixture?
of course! the space between atoms is always very small, but there is always spaces, even in solids
Distinguish between crystals and minerals?
A mineral is any naturally-occuring solid with a defined chemistry and crystalline structure. A crystal is the physical representation of a mineral which is large enough to see, either with the naked eye or hand lens. When minerals are small and need to be seen with a microscope most people start calling them "grains" (ex: a quartz grain in thin-section), but this is not an absolute.
What is the difference between a macro-mineral and a trace element?
A macro mineral is needed in large quantities whereas trace elements are minerals required in small quantities
