NaCl (halite) or KCl (sylvite) is the correct answer.
They are basically checking if it's salty since these minerals are salts by their chemical components.
Redistricting is the process by which new congressional and state legislative district boundaries are drawn. All United States Representatives and state legislators are elected from political divisions called districts. District lines are redrawn every 10 years following completion of the United States census. The federal government stipulates that districts must have nearly equal populations and must not discriminate on the basis of race or ethnicity.[1]
See the sections below for further information on the following topics:
Background: This section summarizes federal requirements for redistricting at both the congressional and state legislative levels. In addition, recent court decisions affecting redistricting policy are summarized.
Methods: This section provides details about the various redistricting processes used in the states.
Competitiveness: This section summarizes some of the arguments about the impact of redistricting on electoral competitiveness. Margin-of-victory and competitiveness data for congressional and state legislative elections is provided for informational purposes.
Majority-minority districts: This section summarizes the legal basis for the creation of majority-minority districts and details some of the arguments surrounding the practice.
Granite is an intrusive igneous rocks made up of different minerals. Granite is made of crystals of biotite, feldspar (orthoclase and plagioclase) and quartz. As weathering acts on the rock it is broken down. Quartz is the most resistant of all the minerals that make up granite and so it will be left after thousands of years of exposure to the processes of weathering and erosion. The main component of sandstone is quartz and it is formed when the weathered sediments leftover from the weathering of the granite rock gets deposited and compacted by the process of sedimentation.
Quartzite is a metamorphic rock formed from sandstone. Sandstone can change into quartzite if it is exposed to extreme heat and pressure inside the crust.
Continental collision occurs when two continental plates move towards each other, each plate being dragged along by convection currents in the mantle. The extreme pressure and heat along these collision zones can cause metamorphism. Granite rocks at these zones can become foliated and change into gneiss.
The rock cycle shows possible paths and processes which crust material (rock)can be subjected to. The three main types of rocks represented on the the cycle are igneous, sedimentary and metamorphic. Igneous rocks are formed when magma or lava cools and hardens. Sedimentary rocks are formed when deposited sediments gets buried, compacted and cemented into hard rock. Metamorphic rocks are formed when preexisting rocks get subjected to extreme temperatures and pressure in the crust.
The Moon appears to change shape because we see different amounts of the lit part as the Moon orbits Earth. From Earth's perspective, we see varying amounts of the illuminated part of the Moon.
