<span>Magma that squeezes into a horizontal crack is called a sill. Magma that squeezes into a vertical crack is called a dike. Both are considered to be rock intrusions wherein magma seeps into the cracks of old sedimentary rock formations. The difference is that sills are tubular and horizontal in nature, while dikes are vertical in nature.</span>
Many progressive movements<span> in </span>Muslim<span> countries involve the rejection of a literal interpretation of the Qur'an. Others involve the rejection of Islamism as a political force, as they believe that religion and government should be separate.</span>
Answer:
Explanation:
At constructive margins such the mid oceanic ridge where new magma are brought to the surface, evidences abounds to support the theory of continental drift through paleomaganetism.
Continental drift is simply the moving of the land masses on earth from their original positions.
There are certain magnetic minerals in rocks that are able to record the prevailing magnetic conditions in a particular terrane. In a hot magma, at the oceanic ridge for example, these minerals align to the magnetic direction at work during the period when they are cooling. As new materials upwells, the cool layer shifts away from the margin each bearing the paleomagnetic record.
Therefore, through a series of reversals and normality in the magnetic direction, one can deduce that the continents actually moves.

Answer:
Your answer would be Checks and Balances.
____________________________________________________
Definition:
Checks and Balances:
A way to "counterbalance" the actions of organizations in the government, which would not give one branch all the power.
____________________________________________________
Explanation:
The reason why "checks and balances" would be the correct answer is because this is a way so that one of the branches in the government doesn't have more power over the other branches.
In your question, it says that the treaty that was signed by the President needs to be approved by 2/3 of the Senate, this would be known as checks and balances because it doesn't give the president all the power since the senate has to approve the treaty. It would not be fair if the president could sign a treaty and it will already go into affect, that would show that the President has more power over the senate. Also, if the president could sign a treaty and it will already go into affect, it would be bad because the President could make whatever treaty they want, and it will automatically pass if checks and balances didn't exist. Without checks and balances, there would be no use for having different branches in the government.

Answer:
Continental crust is about 20 to 70 km thick and thus 70% of this submerged and oceanic crust being about 10 km thick is only 30 % submerged.
Explanation:
- As the hydrological crust is considered to be much denser than the oceanic crust hence at the subduction zones the crusts sink into the mantel and are beneath the lighter continental crust as the oceanic crust is much older than the continental crust. As the continental crust forms many layers and has a bulk composition and the average density is about 2.83 g/cm and has a thickness of about 7 to 10 km.
