Kings gave their land to the lords who in turn controlled the land given by the king.
Hey!
Hope this helps...

The water that makes up icebergs, Antarctica, and such... is water that has stayed in the same place for 100s of thousands of years. Now this water froze and stayed at that height, because the water was at that level before (long ago), you have to remember that at one point in time, it is believed that the Earth was covered only with water, and had no land, besides for the bottom of the water.
Now the water that makes up the surrounding ocean, is water that never froze, and is constantly renewed. Plus it never has the time to freeze, so it cant stay at the specific level. Additionally, the water that makes up the surrounding ocean, is constantly going under water evaporation, and precipitation... Plus the water from those oceans are salty, meaning they can't freeze, and if you cant freeze, you can only melt... so any water from the ocean that freezes, only melts in return...

Answer:</h2>
New crust forms <u>D. at ocean ridges</u>
.
<h2>
Explanation:</h2>
At mid-ocean ridges, there is separating of plate tectonics allowing the formation of new crust from the cool solid magma. The process leads to the formation of the new seafloor and it is called the new seafloor spreading.
Since the earth is not expanding to make way for spreading seafloor, at the subduction zone, the tectonics sink back into lithosphere or earth's interior. The new crust formation at ocean ridges can be a slow or fast process. Some ridges spread at 2 inches (5 centimeters) per year while others spread at 6 inches (15 Centimeter) per year.
It is a lot like the Northern states with having snow every year, but they are different because most of Northern Canada is in the Arctic Circle.
Answer:
1. Participants are randomly assigned to intervention or control
Explanation:
Quasi-experimental study -
It is the study to estimate the impact of an intervention on the target population with any random assignment .
This Quasi-experimental research shares , the similarities with the randomized controlled trial or the traditional experimental design .
But in this study , there is random assignment for the control or treatment .
Hence , from the options given in the question , the correct is ( 1 ) .
