No. Valley glaciers are a few miles to a few tens of miles long. Continental glaciers are hundreds to thousands of miles long.
Yes. A continental glacier spreads around all sides, while the valley glaciers spread along it's length.
A kind of glacier called an "alpine glacier" forms when ice and snow accumulate in a mountain valley. These glaciers flow down the slopes due to gravity, carving out U-shaped valleys and creating distinctive landforms. Alpine glaciers are typically smaller than continental glaciers and are found in mountainous regions around the world.
True. Continental glaciers are large ice sheets that cover vast land areas near the North and South Poles. These glaciers are much larger than alpine glaciers and play a significant role in shaping the landscape through processes like erosion and deposition.
Valley glaciers are streams of flowing ice that are confined by steep walled valleys, often following the course of an ancient river valley. They usually form from Cirques, where the glacier overspills the hollow and begins to travel down the valley. Alternatively, they may form branching off from an ice sheet. The downward erosive action of the ice carves a U shaped valley, as opposed to a V shaped valley for rivers. They have a lot of erosive potential as they are thick bodies of ice exerting extreme amounts of pressure. Valley glaciers 'choose' the most accessible route and erode and enlarge the area. It uses erosional processes, plucking and abrasion. Due to the size and nature of the glacier it can pick up large amounts of debris and scree and deposits it as moraine.
The largest type of ice mass is a continental glacier, also known as an ice sheet. These glaciers cover vast areas of land, often exceeding thousands of square kilometers, and can be found in regions such as Antarctica and Greenland. Continental glaciers are much larger than alpine glaciers, which are confined to mountain ranges. Their immense size and thickness can significantly impact global sea levels and climate.

Yes
Valley glaciers are formed in high altitudes (e.g. mountains) and continental glaciers are formed in high latitudes (e.g. Greenland). Therefore, they both cover land areas but continental glaciers generally cover more area.
The center of a valley glacier moves the fastest due to reduced friction from surrounding valley walls and terrain. This faster flow in the center can cause the glacier to stretch and crack, creating crevasses.
One is bigger than the other one
There are more than three types of glaciers...but I believe you are looking for:Alpine Glacier (found on mountains)Valley GlaciersIce Sheet or Continental GlacierThe USGS has a great site dedicated to just types of glaciers....http://pubs.usgs.gov/of/2004/1216/glaciertypes/glaciertypes.html
Continental and valley glaciers both develop in regions where there is constant snowfall and freezing temperatures throughout the year. Both types of glaciers move at a very slow pace.

No. It is regarded as being smaller than a valley, as it is usually a very narrow channel compared to a valley. It is more commonly created by water, whereas valleys are often caused by glaciers.
Alpine glaciers, even though they move, are confined to mountain valleys, which in most instances had previously been a stream valley. Continental ice sheets exist on a much larger scale. These huge masses flow out in all directions from one or more centers of the land. They cover the entire continent, hence the name, and extend out toward the sea. Only two exist today: Greenland and Antarctica.

As hinted by your question, the valley in Yosemite is carved out by none other than glaciers! Over time, the movement of these large chunks of ice eroded the rocks into the valley we know of today.
