Exploring Earth and Navigation

What is the primary purpose of a compass?

• To indicate direction.

• To measure temperature.

• To calculate distance.

• To determine altitude.

Name the three main layers of the Earth.

• Crust, Mantle, Core

• Shell, Mantle, Crustal Layer

• Inner Shell, Outer Shell, Surface

• Lithosphere, Atmosphere, Hydrosphere

What type of rock is formed from cooled magma?

• Metamorphic rock

• Limestone

• Igneous rock

• Sedimentary rock

How does a compass work in relation to Earth's magnetic field?

• A compass relies on GPS signals to find north.

• A compass functions by detecting the Earth's temperature variations.

• A compass works by aligning its magnetized needle with Earth's magnetic field, pointing towards magnetic north.

• A compass uses solar energy to determine direction.

What is the difference between igneous and sedimentary rocks?

• Igneous rocks are formed from compressed organic material.

• Igneous rocks are formed from molten material, whereas sedimentary rocks are formed from accumulated sediments.

• Sedimentary rocks are formed from volcanic eruptions.

• Igneous rocks are always found underground, while sedimentary rocks are always on the surface.

What is the outermost layer of the Earth called?

• atmosphere

• core

• mantle

• crust

How can rocks be classified based on their formation?

• Rocks can be categorized based on their weight and size.

• Rocks can be classified into igneous, sedimentary, and metamorphic based on their formation.

• Rocks can be classified by color and texture.

• Rocks are classified into organic and inorganic types.

What mineral is commonly found in granite?

• Limestone

• Marble

• Basalt

• Quartz

What is the significance of the Earth's crust?

• The Earth's crust is primarily made of water.

• The Earth's crust is a source of unlimited energy.

• The Earth's crust is essential for supporting life, containing resources, and facilitating geological processes.

• The Earth's crust is responsible for weather patterns.

How do tectonic plates affect the Earth's surface?

• Tectonic plates have no impact on the Earth's surface features.

• Tectonic plates shape the Earth's surface by causing earthquakes, volcanic eruptions, and the formation of mountains and oceanic features.

• Tectonic plates are responsible for the Earth's magnetic field.

• Tectonic plates only affect the climate of the Earth.
