Rocks

What are the three main types of rocks?

• Molten, solidified, and eroded

• Granite, basalt, and slate

• Sedimentary, volcanic, and crystalline

• Igneous, sedimentary, and metamorphic

How are igneous rocks formed?

• Through the evaporation of water

• Through the cooling and solidification of magma or lava.

• Through the compression of sediment

• Through the process of photosynthesis

What is the difference between sedimentary and metamorphic rocks?

• They have the same formation process

• The main difference is in how they are formed.

• They are both igneous rocks

• They are found in the same geological layers

What is the most common mineral found in rocks?

• Feldspar

• Mica

• Gypsum

• Quartz

What is the process of rock cycle?

• The rock cycle is the process of rocks changing from one type to another through sedimentation, metamorphism, and igneous processes.

• The rock cycle involves the movement of rocks through the atmosphere only

• The rock cycle is a rapid process that occurs within a day

• The rock cycle is a man-made process used in construction

What are the properties of sedimentary rocks?

• Density, hardness, cleavage

• Layers/strata, fossils, grain size, composition, texture

• Color, taste, smell

• Temperature, pressure, time

How do geologists classify rocks?

• According to their age

• Based on color alone

• Based on mineral composition, texture, and origin.

• By weight and size

What are the characteristics of metamorphic rocks?

• Foliated or non-foliated textures, banding or layering, presence of minerals like mica, quartz, and feldspar

• Uniform color, lack of layering

• Angular shapes, high porosity

• Smooth texture, absence of minerals

What are the uses of rocks in everyday life?

• Construction, jewelry, grinding, decorations

• Sports, music, art

• Medicine, technology, agriculture

• Cooking, transportation, communication

How do rocks help in understanding Earth's history?

• Rocks do not provide any information about past events

• Rocks are not related to Earth's history

• Rocks contain minerals and fossils that provide clues about past environments, climate conditions, and geological events.

• Rocks are only useful for construction purposes
