Answer:
C: Plates float on the liquid mantle located below the crust.
Explanation:
Plates at our planet’s surface move because of the intense heat in the Earth’s core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Scientists once thought that Earth’s plates just surfed on top of the mantle’s giant convection cells, but now scientists believe that plates help themselves move instead of just surfing along. Just like convection cells, plates have warmer, thinner parts that are more likely to rise, and colder, denser parts that are more likely to sink.
Answer:
The answer is A. The process of breaking down rock and soil.
Explanation:
An example of this will be the grand canyon because it use to be filled with water and all the water was wearing away the rock.
Answer:
Climate change threatens coastal areas, which are already stressed by human activity, pollution, invasive species, and storms. Sea level rise could erode and inundate coastal ecosystems and eliminate wetlands. Warmer and more acidic oceans are likely to disrupt coastal and marine ecosystems.
Answer:
Anyone with access to wireless internet or advanced radio technology
Explanation:
Anyone with access to wireless internet or advanced radio technology have the ability to access GPS systems locally, nationally and world wide.
GPS is the short form of Global Positioning Systems. It is made up of a system of satellites which are used to locate positions on earth. They work on principle of triangulation.
- Most of these system of satellites are accessible over a wireless internet. For example, most of our mobile phone have this ability.
- Also, over advanced radio technology we can access these gps systems. This is used mostly in the military for more secured access.
