Topic 1 = Constructive and destructive natural processes that form different geologic structures and resources
What are the three main types of rocks in the rock cycle?
Answer: Igneous, sedimentary, and metamorphic
What is a landslide?
A landslide is the movement of soil, rock, or debris down a slope. Landslides are a type of mass wasting, which is the movement of soil and rock due to gravity.
What is precipitation?
Precipitation is any form of water, whether liquid or solid, that falls from the atmosphere to the Earth's surface.
What is density?
Density is a measure of how much mass is packed into a given volume, essentially "how heavy something is for its size".
What is Gravity?
Gravity is an invisible force that pulls objects towards each other.
How does an igneous rock become a sedimentary rock
Through weathering, erosion, deposition, and compaction
Where do landslides occur?
Landslides can occur on any slope, but are most common on steep slopes. They can occur anywhere in the world.
What are the different types of precipitation?
Common types include rain, snow, sleet, hail, and freezing rain.
What two measurements must be taken to calculate density?
To calculate density, you need to measure the mass (how much matter an object contains) and the volume (the amount of space an object occupies).
How does Gravity Affect Objects on Earth?
Earth's gravity is what keeps you on the ground.
What process turns a sedimentary rock into a metamorphic rock
Metamorphism, where high temperature and pressure change the rock's mineral structure
When do landslides occur?
Landslides occur when the force of gravity on a slope's material is greater than the material's strength.
How does precipitation form?
Water vapor in the atmosphere condenses and freezes, forming clouds, and eventually falling as precipitation when the water droplets or ice crystals become too heavy.
What units are used to measure density?
Common units for density include grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).
How does Gravity Affect Objects in Space?
The Sun's gravity keeps the Earth in orbit.
What is the role of magma in the rock cycle
Magma cools and solidifies to form igneous rocks
What causes landslides?
Landslides can be caused by heavy rainfall, earthquakes, volcanic eruptions, and more.
What causes thunderstorms?
Thunderstorms are caused by strong updrafts of warm, moist air, which can lead to heavy precipitation, lightning, and thunder.
Why does ice float on water?
Ice is less dense than liquid water because water molecules in ice form a more open, crystalline structure, taking up more space than in liquid water.
Are there any massless particles?
Yes, there are massless particles, namely the photon (carrier of electromagnetism) and the gluon (carrier of the strong force)
How do sedimentary rocks form
Layers of sediment are compacted and cemented together
How can landslides affect people?
Landslides can cause damage to property, roads, and infrastructure. They can also block streams, which can lead to flooding.
What is the difference between a tropical storm and a tropical depression?
A tropical storm is a more intense version of a tropical depression, characterized by stronger winds and heavier precipitation.
How does density affect whether something floats or sinks?
An object will float in a liquid if its density is less than the density of the liquid, and it will sink if its density is greater.
Can gravity form waves?
Yes, gravity can form waves, specifically gravitational waves, which are ripples in spacetime caused by the movement of massive objects, as predicted by Einstein's theory of general relativity.
