Answer:
The place is located at a latitude of 49° to the North from the Equator.
Explanation:
The latitude is the first component of a astronomical location and is defined in a North-South orientation with respect to the Equator, whereas the second one corresponds with the longitude.
Since a place is located at 49° North and 163° West. Hence, the place is located at a latitude of 49° to the North from the Equator.
Biological weathering is caused by living organisms, such as microbes, animals, and plants. Water, oxygen, and rocks are nonliving things (though water and rocks may be capable of weathering), and only plant roots fits the definition of biological weathering. So the correct answer for #1 is A.
Frost wedging occurs when the little water content in rock freezes, expanding and forcing the rock apart. Eventually, enough freeze-melt cycles causes the rock to break apart little by little. This is due to ice's density being less than that of water, meaning that it is because water expands when frozen. So the answer to #2 is A.
Answer:
Stream gradient refers to the slope of the stream's channel .It is the vertical drop of the stream over a horizontal distance.
Explanation:
Gradient is the slope or steepness of a stream channel. It affects the stream's velocity because the steeper the gradient is the greater the velocity due to gravity.

By creating high-paying jobs and providing the raw materials essential to every sector of our economy, minerals mining helps stimulate economic growth. These domestic raw materials—along with recycled materials—were used to process mineral materials such as aluminum, copper, and steel worth $766 billion.
B. It grows as nuclear fusion in its core produces more matter.
