Exploring Rocks and Soils

What is the Big Bang Theory?

• The Big Bang Theory is a scientific theory about the evolution of life on Earth.

• The Big Bang Theory states that the universe is static and unchanging.

• The Big Bang Theory describes the process of human evolution from primates.

• The Big Bang Theory is the leading explanation for the origin of the universe, stating it began from a singularity and has been expanding.

How did the solar system form?

• The solar system was created by a series of cosmic explosions.

• The solar system originated from the remnants of a dying star.

• The solar system formed from the collision of two planets.

• The solar system formed from the gravitational collapse of a giant molecular cloud.

What are the main layers of the Earth?

• Core, Shell, Atmosphere

• Lithosphere, Asthenosphere, Mesosphere

• Crust, Mantle, Atmosphere

• Crust, Mantle, Outer Core, Inner Core

Describe the inner core of the Earth.

• The inner core is a liquid layer composed of magma.

• The inner core is primarily made of silicon and aluminum.

• The inner core of the Earth is a solid sphere made mostly of iron and nickel, with temperatures up to 5,700 degrees Celsius.

• The inner core has a temperature of around 1,000 degrees Celsius.

What is the outer core made of?

• Liquid water and gas

• Solid rock and minerals

• Gaseous hydrogen and helium

• The outer core is made of molten iron and nickel.

What is the mantle and its significance?

• The mantle is the outermost layer of the Earth.

• The mantle is a layer of the Earth located between the crust and the core, significant for its role in tectonic activity and heat transfer.

• The mantle is a solid layer that does not contribute to tectonic movements.

• The mantle is primarily composed of water and gases.

What is the Earth's crust?

• The Earth's crust is the core of the Earth.

• The Earth's crust is a gaseous layer surrounding the planet.

• The Earth's crust is a liquid layer beneath the surface.

• The Earth's crust is the outermost solid layer of the Earth.

Explain the rock cycle in simple terms.

• The rock cycle only involves the formation of igneous rocks.

• The rock cycle describes how rocks are created from minerals without any transformation.

• The rock cycle is a process that only occurs underwater.

• The rock cycle describes the transformation of rocks between igneous, sedimentary, and metamorphic forms.

What are the three main types of rocks?

• Coal, Sandstone, Slate

• Basalt, Shale, Quartzite

• Granite, Limestone, Clay

• Igneous, Sedimentary, Metamorphic

What is an igneous rock?

• Igneous rock is created by the compression of organic materials.

• Igneous rock is a type of rock that forms underwater.

• Igneous rock is formed from the erosion of sediment.

• Igneous rock is a type of rock formed from the solidification of molten material.
