Earth Materials And Different Types of Rocks

What’s a rock

• It is a naturally formed mixture containing minerals, rock fragments, and volcanic glass.

  
  

• It is a solid substance with a fairly well-defined chemical composition and a specific crystal structure that occurs naturally in pure form.

• 
  It is an essential or characteristic part of something abstract.

• It is the simplest form of substance

Igneous Rocks meaning?

• Igneous rocks are those that form from molten rock material that cools and crystallizes either underground or on Earth’s surface.

• They are A basic part of a whole

• • They are those that form from molten rock material that cools and crystallizes either underground or on Earth’s surface.

What is the process of forming igneous rocks?

• They are formed by the cooling and solidification of magma or lava.

• They are formed by the compression of sedimentary rocks.

• They are formed by the metamorphism of existing rocks.

What are the characteristics of sedimentary rocks?

• They are formed from the accumulation and lithification of sediments.

• They are formed from the cooling and solidification of magma or lava.

• They are formed from the metamorphism of existing rocks.

How are metamorphic rocks formed?

• They are formed by the compression of sedimentary rocks.

• They are formed by the cooling and solidification of magma or lava.

• They are formed by the alteration of existing rock through heat, pressure, or chemical processes.

What are the different types of plate boundaries?

• Convergent boundary, Divergent boundary, and Transform boundary

• Convergent boundary, Subduction boundary, and Transform boundary

• Subduction boundary, Divergent boundary, and Collision boundary

What is the process of weathering?

• It is the breaking down of rocks, soil, and minerals as well as artificial materials through contact with the Earth's atmosphere, biota, and waters.

• It is the process of rocks turning into soil over time.

• It is the formation of sedimentary rocks from the accumulation and lithification of sediments.

What are the main components of soil?

• Mineral particles, organic matter, water, and air

• Mineral particles, rocks, and organic matter

• Water, air, and organic matter

What is the process of erosion?

• It is the transportation of rock material from one location to another by natural agents such as water, wind, or ice.

• It is the process of rocks turning into soil over time.

• It is the formation of sedimentary rocks from the accumulation and lithification of sediments.

What are the different types of volcanic rocks?

• Basalt, Andesite, and Rhyolite

• Granite, Gabbro, and Diorite

• Marble, Slate, and Quartzite
