Answer: This material will interact when the galaxies collide. ... There is also friction between the gas in the colliding galaxies, causing shock waves that can trigger some star formation in the galaxies. These processes can radically affect the galaxies. For example, two spiral galaxies can merge to form an elliptical galaxy.
<u>Coquina</u> is the sedimentary rock is made up of pieces of shells.
Two types of sedimentary rock: Clastic and chemical sedimentary rocks
Explanation:
Coquina is the sedimentary rock formed by fragments or pieces of shells of marine animals like mollusks, brachiopods, trilobites and certain invertebrates.
The shells of marine animals are fragmented due to abrasion and mechanical degradation and sorting by the wave action and chemicals present in the sea water and gets transported which then sediments to form rock structures called coquina. The shells mostly contain calcium carbonate.
Chalk is the sedimentary rock formed b the fossil shells fragmented from foraminifers. This is a more powdery type of limestone.
Depending upon the type of sedimentation, sedimentary rocks are of three types:
Clastic – Made from sedimentation of clastic (pieces from broken rocks) through the processes of mechanical weathering and lithification (cementing and compacting). sandstone, conglomerate
Chemical – Made from evaporation of water and precipitation of materials which were previously dissolved in a solution. Example: Rock salt, dolomite
Organic – Repeated accumulation and sedimentation of organic matter or remains from plant and animal sources like bones (calcium deposits). Example: coal.
<span>D. must rely on other means than photosynthesis.
</span>Because sunlight is inadequate at the bottom of the sea, photosynthesis cannot take place. There are no plants and food is scarce; usually decaying matter from dead organisms. Organisms in the bottom of the sea relies on chemicals from hydrothermal vents to create their own food through chemosynthesis.
