For example, if you live in northern California you are more likely to be impacted by a wildfire, landslide, or earthquake than if you live in Charleston, South Carolina, but less likely to be hit by a hurricane. This is because the physical conditions in each place are different. The active San Andreas fault runs through California and causes regular earthquakes, while the warm waters transported by the Gulf Stream can intensify a storm heading for South Carolina.

These environmental hazards shape human activity regionally. Learn more about environmental hazards with this curated resource collection.

Weathering is the process of the weakening and breakdown of rocks, metals, and manmade objects. There are two main types of weathering: chemical and physical. An example of chemical weathering is acid rain. Caused mostly by the burning of fossil fuels, acid rain is a form of precipitation with high levels of sulfuric acid, which can cause erosion in the materials in which it comes in contact. This website is very helpful and I am glad someone I am not sure who created this.

Although this was helpful, I also have many other Wonders. We're glad you liked it, Wonder Friend! Nov 21, We're sorry to hear that, mia! Quincy Oct 26, Oct 29, May 3, Mar 2, Madds Jan 11, How does ski slopes control the avalanches??

I have been in a Big mountain before but I don't know how the control the avalanches? Jan 11, Madds Jan 10, Hey,it's me again! Just wanted to say this was really helpful again and I will be using this website for any other research! Thanks so much Wonder! Dec 16, Howdy, britteny! We're glad you visited Wonderopolis! May 27, Natasha May 17, May 19, Thanks for sharing that information, Natasha!

We appreciate you joining the discussion!

Wonderopolis May 13, Isaac Mar 8, Wonderopolis Mar 8, George Heyward Feb 7, Obviously this is for the person buried in an avalanche and needs to dig their way out.

Wonderopolis Feb 7, I think the simplest way to deterime your up or down position in the snow would be to melt a little snow in your hand and just watch which direction it drips. Tyler J Nov 28, Wonderopolis Nov 28, How do ski areas pervent that from happening? I love playing in the snow but have also realized can be very scary.

Wonderopolis Nov 20, Janhavi Nov 16, Wonderopolis Nov 16, Chloe Nov 14, This worked great for a project. There is a lot of good information! Wonderopolis Nov 14, Wonderopolis Nov 12, I cannot belive an avalanche can cause that much damage!!!!!!!!!!!!!!

Wonderopolis Nov 10, Danny from Mrs. Ski's AM class Nov 10, I have watched videos online about when people get out of the snow by swimming to the surface. I think tomorrow's wonder will be about people who do track or about lighting bolts and how they are formed. What a great Wonder, Alexandria! We are glad you shared it with us! Josephine Nov 10, Wow, I had no idea how powerful an avalanche could be!

Thanks Wonderopolis fo helping me learn something new today. I liked today's wonder it would snow almost every day were we lived. WOW, Blakeleigh! We bet it was quite an experience to be surrounded by snow so often! Mark Nov 10, Yay, first comment! I remember reading about dogs being able to track people stuck in a avalanche. Megan Nov 10, I loved the wonder of the day today! It was sooo cool! Always stay within view of your group. Avalanches may reach the road without warning.

Obey road closures. When the avalanche hazard is high, control work by explosives may be carried out at any time. If an avalanche blocks the highway, remain in your vehicle with seat belts on. Wait for assistance.
