1.4. Membrane transport
Phospholipid bilayers are selectively permeable membranes that control the movement of molecules into and out of cells through passive and active transport mechanisms. Passive transport includes diffusion, facilitated diffusion, and osmosis, which allow molecules to move down their concentration gradients without energy expenditure. Active transport requires energy in the form of ATP to move molecules against their concentration gradients, such as sodium-potassium pumps that repolarize neurons after firing. Membrane transport is essential for cellular functions like nutrient absorption, waste removal, and nerve signal transmission.
Clastic
Detrital sedimentary rocks are formed through the accumulation and compaction of eroded rock fragments that have been transported by water, wind, or ice and deposited in sedimentary basins over time. As additional layers of sediment are deposited, the lower layers undergo compaction and cementation through burial and lithification, forming identifiable strata of solidified sedimentary rock.
Metamorphic rocks
Metamorphic rocks are formed from existing rock types that have undergone intense heat and pressure, causing changes to their mineral composition and structure. There are two main categories of metamorphic rocks - foliated rocks which have a layered or banded appearance due to the development of foliations or planes of crystal alignment under pressure, and non-foliated rocks which have a crystalline structure without distinct layers. Common examples of foliated rocks include slate, schist and gneiss, while non-foliated rocks include marble and quartzite.
Carbonates
Stalactites form from calcium carbonate deposits that accumulate on cave ceilings. Limestone forms from the accumulation of shells and skeletons of living things over time. Fossils can be found embedded in limestone, providing evidence of past life.
Sedimentary rock types
Sedimentary rocks can be categorized into three main types: detrital or clastic, chemical, and organic. Detrital rocks like conglomerate and sandstone are composed of fragments and grains of older rock. Chemical rocks such as limestone, travertine, and gypsum form via precipitation from water. Organic rocks like coal and oil are derived from buried dead plants and animals.
What is a mineral
Minerals are naturally occurring inorganic solid substances that have a definite and homogeneous chemical composition. While minerals are pure substances, impurities can sometimes cause the same mineral to vary in color, such as smoky quartz, white quartz, and rose quartz which are all variations of the mineral quartz.
Classification
Minerals are classified into two main groups - silicates and non-silicates. Silicates contain oxygen and silicon and include quartz, feldspar, mica, olivine and clay minerals. Non-silicates do not contain silicon and include native elements, oxides, sulfides, carbonates, sulfates and halides such as galena, calcite and halite.

Plutonic rocks like granite form deep underground, while volcanic rocks such as basalt and obsidian form above ground during volcanic eruptions and have distinct characteristics based on their composition and texture.
Sedimentary rocks
Sedimentary rocks form in layers or strata and are categorized into detrital, non-detrital chemical, and organic types. Detrital rocks are formed from fragments of pre-existing rocks or organic material. Chemical rocks like limestone form from precipitation of minerals from water. Organic rocks form from remains of living organisms.
Evaporites
Evaporation in hot, dry climates can lead to the precipitation and accumulation of minerals like halite crystals forming rock salt or gypsum crystals. Marshes and coastal lagoons are areas where evaporation exceeds precipitation, allowing for the accumulation of minerals like gypsum in the form of crystals.

Magnitudes
- 2. • A magnitude is a property of the material that we can measure. For example, can we measure the mass of a coin?. Yes, we can. So the mass of a coin is a physical magnitude or magnitude. Can we measure the volume of a coin?. Yes, we can. So the volume of a coin is a physical magnitude or magnitude. We measure the mass We measure the volume with a scale with a test-tube Beauty isn’t a magnitude. We can’t measure it with an instrument or with a machine. However, there’s a world beauty competition every year. Knowledge isn’t a magnitude. We can’t measure it with an instrument or with a machine. However, you have to pass many exams every year.
- 3. We must express a magnitude with a number or quantity and a unit. Magnitude = quantity x unit For example, a car is running at 120 km/h. We express it like: V = 120 km/h Speed, (magnitude) Unit Number or quantity Remember : You always must express the magnitude like a number followed by a unit. Put the unit. Don’t forget it. !
- 4. • All the magnitudes and their units are gathered in a common set called the International System. • Scientists choose an arbitrary number of magnitudes. They are most important. These ones are called fundamental magnitudes. FUNDAMENTAL MAGNITUDES AND THEIR UNITS MAGNITUDE UNIT Length meter (m) Time second (s) Mass kilogram (kg) Temperature kelvin (K)
