Lithification is the process that produces sedimentary rocks which show the Earth's natural past by bringing together sediments into layers of solid rock.
Lithification forms sedimentary rocks. Earth's three main rock kinds are sedimentary, igneous, and metamorphic. Sediments, microscopic particles from pre-existing rocks, minerals, organic materials, or chemical precipitates, accumulate, transport, and deposit at or near the Earth's surface.
Lithification is a multistep process. Sediments are initially deposited in riverbeds, lakes, oceans, deserts, and glaciers. As new sediments are deposited on top, these loose particles are pressured by the weight of higher layers. This pressure compacts sediments, narrowing pore gaps between particles and sticking them together.
During lithification, minerals dissolved in groundwater can precipitate and cement the sediments. Calcite, silica, and iron oxides are sedimentary rocks' main cementing minerals. Sediments become solid rock by cementation.
As pressure rises, dewatering forces water out of sediment pore spaces during lithification. This helps sediment layers compact and solidify.
Lithification creates a cohesive and cemented sedimentary rock that records historical environmental conditions, climate changes, and life on Earth. Sandstone, limestone, conglomerate, shale, and mudstone are sedimentary rocks.
Lithification is essential to the production of sedimentary rocks, changing the Earth's surface and revealing its geological past.

The hormonal, cardiovascular, central nervous and respiratory systems are all involved in this response.
The body is equipped to respond to emergency situations through the fight and flight hormones secreted by the adrenal gland. This chemical messengers send a message to the brain which now causes reactions such as increased pumping of blood by the heart and a faster breathing rate by the lungs.
Hence, the hormonal, cardiovascular, central nervous and respiratory systems are all involved in this response.

Friction reduces the efficiency of engines and other machines by converting parts of their kinetic energy into heat.
Friction makes it possible for you to grasp items with your hand.
Friction enables you to walk.
Explanation:
The disadvantage of friction is that it reduces the efficiency of engines and other machines by converting parts of their kinetic energy into heat.
Friction between moving parts in engines and machines causes resistance, leading to energy loss through heat generation. This energy loss affects the overall efficiency of the system and can lead to increased wear and tear on the components. Engineers often design systems to minimize frictional losses through the use of lubricants, materials with low friction coefficients, or implementing other techniques to reduce friction.
The other statements mention advantages of friction:
- Air resistance of a parachute slows down the descent of a skydiver, which is beneficial for a controlled landing.
- Friction enables you to grasp items with your hand, providing the necessary grip and control.
- Friction also enables you to walk by creating the necessary traction between your feet and the ground, allowing forward motion.
An atom of sodium-23 (atomic number = 11) with a positive charge of +1 has total number of 10 electron and this atom has 11 protons and 12 neutron.
Protons, neutrons, and electrons make up an atom, with hydrogen being the sole exception since it lacks neutrons.
Given: An atom of sodium-23 (atomic number = 11) has a positive charge of +1.
So, total number of electrons it have = 11 -1 = 10.
total number of proton it have = 11.
total number of neutron it have = 23 -11 = 12.

Answer:
While we jump on the diving board then the force is applied by us in the downward direction on the diving board
due to this action force applied by us the diving board goes downwards while due to the reaction force of that diving board we will experience a force in opposite direction
that reaction force will be equal in the magnitude of the force applied by us on the diving board and it is opposite in the direction
so here we will move upwards and lift off the diving board
so this is a great example of newton's III law as per this law every action has equal and opposite reaction force
