• Formation: Formed from the cooling and solidification of molten magma or lava.
• Types:
• Intrusive (Plutonic) Rocks: Formed from magma that cools slowly beneath the Earth's surface, resulting in large, visible crystals. Example: Granite.
• Extrusive (Volcanic) Rocks: Formed from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. Example: Basalt.
• Characteristics: Typically hard and durable, with a crystalline texture. They do not have layers and are often used in construction.
2. Sedimentary Rocks:
• Formation: Formed by the accumulation and compaction of sediments, which can be fragments of other rocks, minerals, and organic material.
• Types:
• Clastic: Made from mechanical weathering debris. Example: Sandstone.
• Chemical: Formed when dissolved minerals precipitate from water. Example: Limestone.
• Organic: Comprised of accumulated plant or animal debris. Example: Coal.
• Characteristics: Often have layered structures (strata) and may contain fossils. They are generally softer than igneous rocks and are important in studying the Earth's history.
3. Metamorphic Rocks:
• Formation: Formed from existing rocks (igneous, sedimentary, or other metamorphic rocks) that have been transformed by heat, pressure, or chemically active fluids.
• Types:
• Foliated Metamorphic Rocks: Have a banded or layered appearance due to the alignment of mineral grains. Example: Schist.
• Non-Foliated Metamorphic Rocks: Do not have a banded texture. Example: Marble.
• Characteristics: Typically harder and more resistant to weathering than their original forms. They often have a distinctive banded or crystalline appearance and are used in architecture and sculpture.

Meaning of 'Tundra':

• Definition: Tundra is a type of biome characterized by its cold temperatures, low precipitation, and a landscape that is primarily composed of permafrost, or permanently frozen ground.
• Climate: It experiences long, harsh winters with temperatures often dropping below freezing and short, cool summers.

Divisions of the Tundra Region:

1. Arctic Tundra:
• Location: Found in the northernmost parts of the world, including regions of Alaska, Canada, Greenland, and Russia.
• Climate: Extremely cold with long winters and short summers. The ground is covered in permafrost.
2. Alpine Tundra:
• Location: Found at high altitudes in mountain ranges around the world, above the tree line.
• Climate: Similar to the Arctic Tundra but with more moderate temperatures due to altitude rather than latitude.

Plant Resources:

• Adaptations: Plants in the tundra have adapted to survive the extreme cold and short growing seasons. They are typically low-growing to avoid damage from strong winds and to conserve heat.
• Common Plants:
• Mosses and Lichens: These are the most common and can grow directly on the permafrost.
• Grasses and Sedges: These plants are adapted to the cold and have short roots to survive in the shallow active layer of soil.
• Dwarf Shrubs: Such as the Arctic willow and bearberry, which stay close to the ground to conserve heat.

Animal Resources:

• Adaptations: Animals in the tundra have developed various adaptations to survive the cold, such as thick fur, fat reserves, and behaviors like migration and hibernation.
• Common Animals:
• Mammals: Includes the Arctic fox, caribou, polar bear, and musk ox. These animals have thick fur and fat layers to insulate against the cold.
• Birds: Many birds, such as the snowy owl and Arctic tern, migrate to the tundra during the short summer to breed.
• Insects: Despite the cold, there are various insects, including mosquitoes and midges, which emerge during the brief summer.

The tundra biome, despite its harsh conditions, supports a unique array of plant and animal life that has adapted to the extreme environment. These adaptations are crucial for their survival and play a significant role in the ecosystem of the tundra.
