Weathering
What is the process called that breaks down rocks into smaller pieces?
What is weathering?
What are the three main types of rocks?
What is Igneous, metamorphic, and sedimentary rocks?
What are the four main layers of the Earth?
What is the crust, mantle, outer core and inner core?
What is plate tectonics?
What is the theory that Earth's outer shell is divided into several plates that glide over the mantle?
What causes the seasons on Earth?
What is the tilt of Earth's axis as it orbits the Sun?
Name one factor that can speed up the weathering process.
What is increased moisture (water)?
Describe the process of sedimentary rock formation.
What is deposition, compaction and cementation of sediments over time?
Which layer of the Earth is liquid?
What is the outer core?
Name the three types of plate boundaries.
What is moving towards, away and along the boundaries?
How does the tilt of the Earth's axis affect seasons?
What is it causes different parts of the Earth to receive varying amounts of sunlight throughout the year, leading to seasonal changes?
What type of weathering involves the chemical alteration of minerals?
What is chemical weathering?
How does metamorphic rock form from existing rocks?
What is undergoing intense heat and pressure?
Describe the characteristics of the mantle.
What is mostly solid, but can flow?
What causes the movement of tectonic plates?
What is uneven heating of Earth's asthenosphere?
What season occurs in the Northern Hemisphere when it is summer in the Southern Hemisphere?
What is winter?
How does biological weathering occur?
What is living organisms break down rocks through physical or chemical means?
What is the role of heat and pressure in the rock cycle?
What is transforming rocks from one type to another?
What is the Earth's core mainly made of?
What is iron and nickel?
Tectonic plates movement are?
What move towards, away and slide past each other?
Describe how the length of daylight changes throughout the seasons.
What is daylight hours vary because of Earth's tilt; summer has longer days and shorter nights, and winter has shorter days and longer nights?
What is causing expansion and contraction in rocks?
Explain how igneous rocks are formed.
What is cooling and solidification of magma or lava?
Explain how the crust differs from the mantle.
What is the crust is Earth's outermost layer, thin and rigid, mantle is thicker and more plastic.
What is happening at the Mid-Atlantic Ridge?
What is the plates (North American) are moving away from each other (Eurasian)?
Explain the difference between solstices and equinoxes.
What is Solstices mark the longest (summer) and shortest (winter) days of the year, while equinoxes mark days with equal day and night lengths (spring and autumn)?
