What else can I help you with?
True or false continental crust is composed mainly of less dense relatively lightweight basaltic rocks including the minerals quartz and feldspar?
False. Continental crust is mostly composed of less dense granite and granodiorite rocks, which contain minerals such as quartz, feldspar, and mica. Basaltic rocks are more characteristic of oceanic crust.
True or false continental crust is made of rocks such as granite?
True. Continental crust is primarily composed of lighter rocks such as granite, which are less dense than the basaltic rocks found in oceanic crust. This is why continental crust is thicker and less dense than oceanic crust.
True or False Olivine and quartz commonly crystallize together from mafic or basaltic magmas?
false. SiO2 + CaMg(CaCO3)2 -> MgSiO4 + CaCO3 + CO2 (not balanced) Quartz + Dolomite -> Forsterite +Calcite + excess CO2 that is released as gas Forsterite is a type of olivine. Olivine's chemical formula is (Mg,Fe)SiO4, with the Mg as forsterite and the Fe as fayelite. Oceanic crust is rick in basalt and gabbro and these rocks have a very low quartz content or are void of it. Continental crust contains a large amount of granitic rocks from which quartz is found in most frequently. Olivine usually forms in very hydrous situations where there is water involved, and comes from oceanic crust usually.
A volcanic mountain with gently sloping sides built almost entirely out of basalt lava flows is called a cinder cone.?
Actually, a volcanic mountain with gently sloping sides made of basalt lava flows is typically called a shield volcano, not a cinder cone. Cinder cones are typically smaller, steeper-sided volcanoes formed from ejected rock fragments.
Is the sun's structure is uniform throughtout its interior with no evidence of different layers?
No, the sun's structure is not uniform throughout its interior. The sun has different layers, including the core where nuclear fusion occurs, the radiative zone, and the convective zone. These layers have different temperatures and densities, leading to distinct regions with varying properties.
What does it mean if a micrograph is false-colored?
When a micrograph is false-colored, it is when scientists use computer technology to change/add colors in the cell structure to make certain areas stand out due to the light.

When a micrograph is false-colored, it is when scientists use computer technology to change/add colors in the cell structure to make certain areas stand out due to the light.
True or false As the concentration of a colored solution increases the absorbance value decreases?
Absorbance rises with concentration because there is more material for a given frequency of light to be absorbed in. Your statement is false.
When light passes into a more dense material it bends away form the normal true or false?
False. When light passes into a more dense material, it bends towards the normal. This phenomenon is known as refraction, and it occurs due to the change in speed of light as it moves from one medium to another with different optical densities.
Is density a given mineral that can have varying densities?
Not exactly sure what you mean...do you mean "true or false: a given mineral can have varying densities?" If you do mean that, than the answer is true.
A typical dress code in a private school is dark pants and light colored shirt is it true or false?
False. The typical dress code in a private school can vary depending on the individual school's policies. Some private schools may require dark pants and a light-colored shirt, while others may have different dress code requirements. It's best to check with the specific school for their regulations.
What is the duration of False Light?
The duration of False Light is 1.5 hours.
An optical microscope uses ordinary white light to illuminate a polished sample true or false?
Not entirely true. It does not have to be a polished sample. It is often a transparent or semitransparent sample and the source of illumination can be a colored light or polarized light to bring out the features that need to be examined.
True or false continental crust is composed mainly of less dense relatively lightweight basaltic rocks including the minerals quartz and feldspar?
False. Continental crust is mostly composed of less dense granite and granodiorite rocks, which contain minerals such as quartz, feldspar, and mica. Basaltic rocks are more characteristic of oceanic crust.
Does the lens of the eye control the amount of light that strikes the retina?
No, the lens of the eye helps to focus light onto the retina, but it does not control the amount of light that strikes the retina. The iris, the colored part of the eye, controls the amount of light entering the eye by adjusting the size of the pupil.
When was False Light created?
False Light was created on 1993-02-04.
A fluorescent light source emits light as a result of high temperature?
false
