What is a Pangea and how long ago did it form?
The hypothetical landmass that existed when all the continents were joined, from about 250 million years ago.
How is freezing and thawing a process of weathering?
Water expands when it freezes acting like a expanding until it breaks of pieces of rocks.
What is a streak?

Do earthquakes cause volcanoes?
Sometimes
Which element was discovered first: xenon or neon?
What is the theory of plate tectonics?
Earths outer shell(lithosphere) is divided into several plates that glide over the earths rocky inner layer above the soft core(mantle)
What Is a process of mechanical weathering?
Freezing and thawing and release of pressure
What is a mineral?
A naturally occurring, inorganic, solid that has a crystal structure and a definite chemical compostition
Where do earthquakes or volcanoes mostly occur? You only have to answer for one.
Around the edges of the Pacific Ocean/In the Ring of Fire.
What is the rarest blood type?
What causes seismic waves?
Sudden movement of materials within the Earth, such as slip along A fault during an earthquake
what three factors affect the rate of weathering
surface area, rock composition, and location
What type of rock needs to be crystallized?
Igneous rock
Can volcanoes be predicted?
Reliable forecasts are rarely possible more than a few days in advance of an eruption
Who first identified DNA or its structure?
Friedrich Miescher/ James Watson and Francis Crick
What plate displays the highest and most active earthquake activity?
Pacific plate
What are three agents of chemical weathering?
Water, oxygen, carbon dioxide, living organisms, and acid rain
What is a crystal system?
Crystals grow atom by atom to form a particular structure - these structures are grouped into six different categories see on the number and angle of the crystal faces.
What are the three types of volcanoes?
Cinder cones, composite volcanoes, and shield volcanoes
What is mitosis?
Mitosis is the process by which a cell replicates its chromosomes and then segregates them, producing two identical nuclei in preparation for cell division.
