What are the 4 main features of plate tectonics?

There are 4 main types of plate boundary including: convergent, divergent, subduction and transform – the type of boundary influences the features and events which occur.

What are the characteristics of the three types of plate boundaries?

Loved by our community
  • convergent boundary = when plates move towards each other , they form convergent boundary.
  • divergent boundary = when plates move away fro. each other , they form divergent boundary.
  • transform boundary. = when plates slide past each other, it is called transform boundary.

What are the four types of tectonic plates?

Plate Boundaries: Convergent, Divergent, Transform.

What are the two main factors of tectonic plates movement?

Heat and gravity are fundamental to the process

Lithospheric plates are part of a planetary scale thermal convection system. The energy source for plate tectonics is Earth’s internal heat while the forces moving the plates are the “ridge push” and “slab pull” gravity forces.

What is the 7 major tectonic plates?

There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.

What is a fact about tectonic plates?

Tectonic plates are responsible for volcanoes, earthquakes, and tsunamis. What is this? The Ring of Fire is a location on Earth where the big tectonic plates meet and push against each other. When a heavy tectonic plate pushes under a light tectonic plate, the lighter one rises up and becomes a volcano.

What are tectonic plates made of?

A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere.

What is the 7 major tectonic plates?

There are major, minor and micro tectonic plates. There are seven major plates: African, Antarctic, Eurasian, Indo-Australian, North American, Pacific and South American. The Hawaiian Islands were created by the Pacific Plate, which is the world’s largest plate at 39,768,522 square miles.

What geologic features form at the surface of plate A?

The geologic features that might form at the surface of Plate A are the following: (i) Volcanic eruptions. (ii) Trenches. (iii) Earthquakes.

How many plate tectonics are there?

seven major
There are seven major tectonic plates. Major tectonic plates tend to be at least 20 million square kilometers in size. The Earth’s major tectonic plates are: African Plate.

How many major tectonic plates are there?

seven major
Layers of the earth. Together, the crust and the upper part of the mantle form the lithosphere, Earth’s solid outer shell. This rocky, brittle layer is broken up into seven major and several minor tectonic plates (also known as lithospheric plates) that fit together like puzzle pieces.

What are geological characteristics?

Geologic characteristics are responsible for soil formation, landscape shape and erodibility. These characteristics of basic geology influences plant growth and animal habitat, distribution, and migration patterns. Geologic issues are often key to resource planning and management on a watershed scale.

Which geologic feature is formed in the divergent plate boundary?

A divergent plate boundary often forms a mountain chain known as a ridge. This feature forms as magma escapes into the space between the spreading tectonic plates.

What geologic features is are formed?

Geologic features created by the influence of tectonic forces include folds, which are bent or tilted layers in sedimentary rocks and faults that offset rock layers and fractures in rocks as well as mountains. Plate tectonics creates mid-ocean ridges and deep ocean trenches at subduction zones.

What are the four geological features?

What processes shape Earth’s surface? The four major geological processes are impact cratering, volcanism, tectonics, and erosion.

What geologic features and events are evidence of the movement of the tectonic plates?

Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.

What are the 3 geological processes?

Geological processes
  • Erosion. Erosion involves the movement of rock fragments through gravity, wind, rain, rivers, oceans and glaciers.
  • Weathering. Weathering is the wearing down or breaking of rocks while they are in place.
  • Deposition. …
  • Landforms. …
  • Relief.
