What are three types of sedimentary rocks? How do they form? Pls give a legit answer thats not off of google for thank you.

Three types of sedimentary rocks are, clastic, organic (biological), and chemical. Clastic rocks are formed by made up of pieces (clasts) of pre-existing rocks. Organic rocks are formed by accumulation and lithification of organic debris, such as leaves, roots, and other plant or animal material. Last but not least chemical rocks are formed by precipitation of minerals from water. Precipitation is when dissolved materials come out of water.

the oxygenated blood then leaves the lungs through pulmonary veins, which return it to the left heart, completing the pulmonary cycle. this blood then enters the left atrium, which pumps it through the mitral valve into the left ventricle. from the left ventricle, the blood passes through the aortic valve to the aorta.

deoxygenated blood leaves through the right ventricle through the pulmonary artery. from the right atrium, the blood is pumped through the tricuspid valve (or right atrioventricular valve), into the right ventricle.
