Types of Rocks Quiz

Where do igneous rocks come from?

• From the Earth's surface

• From fusing smaller pieces of sand, soil, and rock

• From lava that has flowed from a volcano and then cooled

• From deep under the surface of the Earth

What makes igneous rocks lighter than most rocks?

• They are very hard and crumble easily

• They contain shiny particles

• They are formed in or near areas of water

• They start off as a liquid and have air bubbles

Where are sedimentary rocks often formed?

• Deep under the surface of the Earth

• In or near areas of water like lakes, oceans, and rivers

• On the Earth's surface

• In areas with a lot of weight, pressure, and heat

What do you often see in sedimentary rocks?

• Different things, even fossils

• Layers that may contain shiny particles

• Ribbons and layers

• Fossils and shiny particles

How are metamorphic rocks formed?

• From lava that has flowed from a volcano and then cooled

• From smaller pieces of sand, soil, and rock fusing together over time

• From the Earth's surface

• From igneous or sedimentary rocks that went through a change

Where do metamorphic rocks form?

• On the Earth's surface

• Deep under the surface of the Earth

• In or near areas of water like lakes, oceans, and rivers

• In areas with a lot of weight, pressure, and heat

What makes metamorphic rocks very hard?

• They contain shiny particles

• They are very hard and crumble easily

• They start off as a liquid and have air bubbles

• They have gone through years of weight, pressure, and heat

What do you often see in metamorphic rocks?

• Layers that may contain shiny particles

• Fossils and shiny particles

• Ribbons and layers

• Different things, even fossils

What is the main difference between igneous and sedimentary rocks?

• Igneous rocks are very hard and crumble easily, while sedimentary rocks are lighter than most rocks

• Sedimentary rocks are often formed in or near areas of water, while igneous rocks start off as a liquid

• Igneous rocks are formed on the Earth's surface, while sedimentary rocks come from lava

• Sedimentary rocks are formed from smaller pieces of sand, soil, and rock fusing together over time, while igneous rocks come from lava that has flowed from a volcano and then cooled

What is the main difference between sedimentary and metamorphic rocks?

• Sedimentary rocks are often formed in or near areas of water, while metamorphic rocks start off as a liquid

• Metamorphic rocks often contain many different things that have been fused or squished together over time, while sedimentary rocks are often softer and crumble easily

• Sedimentary rocks are formed from smaller pieces of sand, soil, and rock fusing together over time, while metamorphic rocks have gone through years of weight, pressure, and heat

• Metamorphic rocks are very hard and you can see ribbons, like layers, that may contain shiny particles, while sedimentary rocks start off as sediment that hardens over time into a rock
