Formation of Extrusive and Intrusive Rocks:
Extrusive Rocks:
– Formation: Result from rapid cooling of lava on the Earth’s surface during volcanic eruptions.
– Cooling Rate: Quick cooling leads to fine-grained or glassy textures.
– Examples: Basalt and obsidian are common extrusive rocks.
Intrusive Rocks:
– Formation: Formed from slow cooling of magma beneath the Earth’s surface.
– Cooling Rate: Slow cooling results in coarse-grained textures.
– Examples: Granite and diorite are typical intrusive rocks.
Distinct cooling rates influence textures, creating differences between extrusive and intrusive rock types.
Rock Cycle Explanation: 1.

Rock Cycle Explanation:
1. Formation:
– Igneous rocks form from cooled magma/lava.
– Sedimentary rocks form from sediment deposition and compaction.
– Metamorphic rocks form from existing rocks altered by heat/pressure.
2. Transformation:
– Igneous rocks can weather into sediments.
– Sediments can compact to form sedimentary rocks.
– Any rock type can undergo metamorphism to become metamorphic rocks.
3. Recycling:
– Melting and solidification form new igneous rocks.
– Weathering and erosion form sediments.
– Metamorphism creates new metamorphic rocks.
The rock cycle depicts how rocks transform between types through geological processes, demonstrating Earth’s dynamic nature.

Definition of a Rock:
A rock is a naturally occurring solid material found on Earth’s surface composed of minerals or mineral-like substances. It forms through geological processes such as cooling of molten magma, sediment deposition, or metamorphic changes due to heat and pressure. Rocks come in various types, including igneous (formed from cooled magma), sedimentary (formed from compacted sediments), and metamorphic (altered by heat and pressure). They vary in composition, texture, and color, playing a significant role in the Earth’s crust and landscape formation.
Layers of the Earth: 1. Crust: The Earth's outer layer, divided into oceanic and continental crust, composed of solid rock. 2.

2. Mantle: Located beneath the crust, it consists of semi-solid, hot rock, divided into upper and lower sections.
3. Core: The innermost layer:
– Outer Core: Molten iron and nickel in a liquid state.
– Inner Core: Solid ball of iron and nickel due to extreme pressure despite high temperatures.
These layers differ in composition and state of matter, contributing to the Earth’s structure and geological processes.

Parasites live off living organisms, causing harm to obtain nutrients, like ticks or tapeworms. Saprotrophs, such as fungi and certain bacteria, feed on dead matter without harming living organisms. Parasites depend on hosts for survival, while saprotrophs decompose dead materials, returning essential nutrients to the environment. Understanding their differences helps grasp how parasites harm living hosts, whereas saprotrophs contribute to ecosystems by recycling nutrients from dead organic matter without causing harm.
