Easy Mind MapsWhat is Weathering? Types of Weathering 1. Physical Weathering (Mechanical Weathering) Examples of Physical Weathering ✅ Frost Action (Freeze-Thaw Weathering) – Water enters rock cracks, freezes, expands, and breaks the rock.✅ Thermal Expansion – Repeated heating and cooling cause rocks to crack.✅ Exfoliation – Outer rock layers peel off due to temperature changes.✅ Abrasion – […]
Earthquakes are sudden vibrations of the Earth’s surface caused by tectonic plate movements, volcanic activity, or human actions. They originate at a focus point and are measured by scales like Richter and Moment Magnitude. Major earthquake zones include the Pacific Ring of Fire. Preparedness and understanding earthquake effects are vital for safety.
A volcano is an opening in the Earth’s crust where magma, gases, and ash escape. They can be active, dormant, or extinct, with various eruption types and effects. Key volcanic zones include the Ring of Fire and the Mid-Atlantic Ridge. Volcanoes enrich soil, create land, and pose hazards like lava flows and ash clouds.

A delta is a triangular landform created at a river’s mouth where sediment is deposited, forming numerous distributaries. There are various types, including arcuate, bird’s foot, estuarine, cuspate, and inland deltas. Deltas support agriculture, biodiversity, and human settlements, being significant for economic activities and environmental health.
A valley is a low area between hills, often created by erosion or tectonic shifts, and can be classified into types such as river, glacial, rift, structural, and hanging valleys. Valleys are significant for agriculture, river systems, human settlements, and biodiversity, supporting various civilizations throughout history.
Mountains are significant natural elevations of the Earth’s surface, covering 25% of land area and influencing climate, biodiversity, and water sources. They can be classified into fold, block, volcanic, residual, and dome mountains, each with distinct characteristics. Mountains play a vital role in tourism, agriculture, and mineral resources.
The Earth is the third planet from the Sun, featuring a diameter of 12,742 km, a protective atmosphere, and a unique magnetic field. It has one natural satellite, the Moon, which orbits Earth every 27.3 days. Their relationship affects tides and eclipses, showcasing significant natural phenomena on Earth.
The Earth experiences two main motions: rotation, which takes 24 hours, causing day and night, and revolution, which occurs in 365.25 days, leading to seasons. These motions also influence time zones and the Earth’s shape. Key concepts include perihelion, aphelion, solstices, and equinoxes, crucial for understanding Earth’s climate and calendar.
