Lithosphere S2T4 Week 2

What is the lithosphere?

• The solid shell of the earth divided into a crust and mantle

• The layer of the atmosphere closest to the earth's surface

• The layer of the earth's surface where living organisms exist

• The layer of the earth's core made of molten iron and nickel

What is the importance of the lithosphere?

• Source of valuable resources like minerals and fossil fuels

• The region of the earth's core where nuclear reactions occur

• The layer of the earth's surface where most earthquakes happen

• The layer of the earth's atmosphere responsible for weather patterns

How are igneous rocks formed?

• From the accumulation of once-living organisms on the earth's surface

• From the transformation of preexisting rocks under high pressure

• From the compaction and cementation of sediment

• From the cooling and solidification of molten rock

What are sedimentary rocks formed from?

• The transformation of preexisting rocks under high pressure

• The cooling and solidification of molten rock

• The accumulation of volcanic ash on the earth's surface

• Deposits of pre-existing rocks or pieces of once-living organisms

How do metamorphic rocks form?

• From the compaction and cementation of sediment

• From the cooling and solidification of molten rock

• Due to the transformation of preexisting rocks in response to environmental changes

• From the accumulation of volcanic ash on the earth's surface

What is the basic material for the formation of the lithosphere?

• Magma

• Sediment

• Volcanic ash

• Lava

What is the lithosphere composed of?

• The outermost layer of the atmosphere

• The liquid layer of the earth's core

• The crust and the brittle part of the upper mantle

• The layer of the earth's surface where oceans exist

What is the source of useful minerals and elements like iron and copper?

• The hydrosphere

• The biosphere

• The lithosphere

• The atmosphere

What causes the formation of mountains, volcanoes, and continents?

• Volcanic eruptions

• Impact of meteorites

• Erosion by wind and water

• Shifting of tectonic plates

What undergoes gradual change over millions of years to form fossil fuels?

• Biotic remains buried in the lithosphere

• Volcanic rocks on the earth's surface

• Sedimentary rocks in riverbeds

• Metamorphic rocks deep underground
