For one to start over from scratch
The idea of a blank slate is to be wiped clean, and there be nothing there. So someone can start over and rebuild whatever it is they had, or start completely new.
wegener’s theory of continental drift; hess proposed the idea that mid ocean ridges are where crust is created
1. Select the correct answers from the list.
Scientists wondered how volcanoes could be located so far from tectonic plate boundaries until one proposed the idea of hotspot magmatism, where the magma is much hotter than the surrounding magma. These are mantle plumes and do not move with tectonic plates. They are responsible for the creation of volcanic island chains such as Hawaii.
Hotspot magmatism occurs far away from lithospheric plates. They result from rising mantle plumes which does not move with the plate thereby when they reach the surface, they cool and solidify to form series of volcanic island chains.
2. a rising magma
All volcanoes have rising magma. In fact, volcanoes are surface features formed by magma that reaches the earth surface.
3. d They were warm climate plants that would not grow in a cold polar area.
These fossil types might have spread when the continental masses were joined together. As oceans came up, continents drifted to their present position due to plate tectonics.
4. Type of lava, steepness, height
when we talk about volcanoes, earth scientists are interested in a couple of factors such as lava types, steepness, height of volcano, viscosity, explosivity and the likes.
5. c The plates push up, forming a mountain range.***
At collision margin between two continental plates having similar rock densities, a push up will occur. This woud lead to the formation of mountain ranges around due to the collision.
The first one is continential drift, The second one is mid ocean ridges. I took the test
The idea of Popular Sovereignty means that government is created by the people and for the people.
The idea of government by the people and for the people essentially represents the popular sovereignty concept. It is a kind of government whereby the representatives governing the country are elected by the citizens.
The idea of popular sovereignty is based on the notion that the people are supreme or sovereign. In the history of U.S., the idea of popular sovereignty is reflected in the Declaration of Independence of 1776, Gettysburg Address of 1863. It upholds the notion of civil liberties as well as rule of law.
¡Qué buena idea!
