Earth Science Concepts and Phenomena

The video explores Earth and space sciences, covering Earth's rotation, orbit, and their effects on day, night, and seasons. It discusses lunar phases, tides, and the solar system, including the Pluto debate. The Earth's axial tilt and its role in seasons are explained, along with the types of rocks and minerals. The video concludes with an overview of plate tectonics and how they shape landforms.

What causes the cycle of day and night on Earth?

• The Sun's movement around Earth

• Earth's rotation on its axis

• The Moon's orbit around Earth

• Earth's revolution around the Sun

How long does it take for Earth to complete one full rotation?

• 30 days

• 12 hours

• 365 days

• 24 hours

What is the primary cause of the different phases of the Moon?

• The Sun's position in the sky

• The Moon's orbit around Earth

• The Earth's shadow on the Moon

• The Moon's distance from Earth

What are spring tides?

• Tides that occur in the spring season

• Tides with the least difference between high and low water

• Tides with the greatest difference between high and low water

• Tides caused by the Moon's phases

Why was Pluto reclassified as a dwarf planet?

• It is too small to be a planet

• It is not round in shape

• It has not cleared its orbit of other objects

• It does not orbit the Sun

What is the main difference between comets and asteroids?

• Asteroids are larger than comets

• Comets are made of rock, asteroids of ice

• Comets have tails, asteroids do not

• Asteroids orbit the Sun, comets do not

What causes the seasons on Earth?

• Earth's distance from the Sun

• Earth's tilt on its axis

• The Sun's rotation

• The Moon's gravitational pull

How are time zones determined?

• By the Earth's rotation

• By the Earth's revolution

• By the Sun's position

• By the Moon's phases

What type of rock is formed from cooled magma?

• Metamorphic rock

• Sedimentary rock

• Igneous rock

• Mineral rock

What is the process called when tectonic plates move apart?

• Transform boundary

• Subduction

• Convergent boundary

• Divergent boundary
