TEKTONISME DAN PENGARUHNYA TERHADAP KEHIDUPAN (TUGAS GEOGRAFI SMA NEGERI 1 TABANAN)

Summary

In this educational video, the presenter explains the concept of tectonism and its impact on life on Earth. Tectonism, or tectonic forces, involves the shifting and deformation of Earth's layers, either horizontally or vertically. The video covers two main types of tectonic movements: epigenetic (slow, widespread shifts) and orogenetic (faster, localized processes leading to mountain formation). The presenter also discusses the effects of these movements, including the creation of diverse landscapes like mountains, lakes, and rivers, as well as their environmental impact, such as extreme weather and potential for natural disasters.

Takeaways

• 😀 Tektonism refers to the shifting and deformation of Earth's layers, both horizontally and vertically.
• 😀 Tektonism is divided into two types: epigenetic and orogenetic movements.
• 😀 Epigenetic movement involves gradual shifts of tectonic plates over large areas, affecting the Earth's surface.
• 😀 There are two types of epigenetic movement: positive (land sinking) and negative (land rising).
• 😀 Orogenetic movement results in the formation of mountains and occurs over shorter periods in smaller areas.
• 😀 Orogenetic movements create folds and faults in the Earth's crust.
• 😀 Folds are caused by horizontal pressure that causes Earth's layers to bend, resulting in different types of folds, such as tilted, hanging, vertical, isoclinal, and overturned folds.
• 😀 Faults are fractures in Earth's layers caused by movements that can lead to Earth’s surface breaking. Types of faults include normal, reverse, horizontal, and oblique.
• 😀 Positive impacts of folds and faults include the creation of diverse landforms like lakes, rivers, mountains, and forests, as well as rich mineral deposits.
• 😀 Negative impacts of folds and faults can include shifts in the Earth’s surface, extreme weather conditions, and natural disasters like floods, droughts, and strong winds.

Q & A

What is Tektonism?

Tektonism, or tectonic forces, refers to the movement and transformation of Earth's crust, involving both horizontal and vertical shifts in the Earth's layers.

What are the two main types of Tektonism?

The two main types of Tektonism are Epirogenetic movement and Orogenetic movement.

What is Epirogenetic movement?

Epirogenetic movement refers to slow shifts in tectonic plates that cover large areas. It can be either positive, where land sinks causing sea levels to rise, or negative, where land rises and sea levels appear to lower.

What is Orogenetic movement?

Orogenetic movement is the process of mountain formation through more localized and faster tectonic movements, leading to the creation of folds and faults.

What are folds in tectonics?

Folds are bends or creases in Earth's layers caused by horizontal pressure. There are various types of folds, such as tilted, hanging, upright, isoclinal, and plunging folds.

What are faults in tectonics?

Faults are fractures in Earth's crust caused by tectonic movement. The parts of the Earth's surface on either side of the fault may shift, creating features like grabens (lowered areas) and horsts (raised areas).

What are the different types of faults?

The types of faults include normal faults, reverse faults, strike-slip faults, and thrust faults, each distinguished by the direction of the movement that causes them.

How do tectonic movements affect the Earth's surface?

Tectonic movements can lead to shifts in the Earth's surface, such as cracks, subsidence, or uplift, as well as the formation of landforms like mountains, valleys, and plateaus.

What are some positive effects of tectonic movements on the environment?

Positive effects include the creation of diverse landforms such as lakes, valleys, rivers, and mountains, which contribute to biodiversity. Areas affected by tectonics are often rich in natural resources, benefiting human societies.

What are some negative impacts of tectonic movements?

Negative impacts can include environmental changes like landslides, floods, earthquakes, and extreme weather patterns. These can alter ecosystems and pose risks to human infrastructure and safety.
