streak
geologists can study a rock sample by observing its composition, color, and texture. they also look at the rocks structure, hardness and weight.
Because granitic rocks are poor in iron and magnesium, which gives basaltic rocks it dark color.
The Weathering Cycle.
the rocks are called irone

The mineral constituents of rocks are the major source of their color.
It can. Some of the abrasive material might come from finely powdered rock, as can the flourine.
An iceberg composition is almost entirely ice, with some rocks and other material's. white in color and the color of the rocks and minerals.
They are called clastic sedimentary rocks.

Fossils are only found in rocks that are laid down on the surface of the Earth. The majority of fossiliferous rocks are therefore sedimentary BUT fossils are also occasionally found in lava flows (igneous rocks) - eg lava trees and in some metamorphosed sedimentary rocks (metamorphic rocks) - eg the "delabole butterfly"
