1. Tectonic plates move slowly due to Earth's mantle convection currents, like hot water rising and falling in a pot.
2. Need missing word from #1 for explanation.
3. Label "Transform" as given. Identify features like ridges (divergent) or mountain ranges (convergent) for other boundaries.
1. Reason for Tectonic Plate Movement:
The statement correctly points out that tectonic plates move due to convection currents in the Earth's mantle. These currents are driven by the heat within the planet, causing hot, less dense molten rock to rise, and cooler, denser rock to sink. This circular motion creates a drag on the overlying tectonic plates, causing them to move horizontally across the Earth's surface.
2. Meaning of the Word:
Unfortunately, without knowing the specific word labelled "B" in #1, I can't explain its meaning. Please provide the missing word, and I'll be happy to analyze it and provide its context within the sentence.
3. Types of Plate Boundaries:
Transform: This label is already provided and is correct if the image shows two plates sliding past each other horizontally with no significant change in size or direction.
Divergent: Look for features like mid-ocean ridges, characterized by rifts and valleys as plates move apart, creating new oceanic crust.
Convergent: Identify features like subduction zones, where one plate plunges beneath another, or mountain ranges formed by colliding plates.
