"Hectare" is a unit of area. It has no qubic meters in it.
1 yard of dirt = 1.45 tons of dirt The above is a function guideline, but it really depends on the type of dirt in question, and how wet that dirt is. For baseball dirt I like to use 1 yard = 1.3 tons
27 square feet. A "yard" is a short form of "cubic yard" of something...dirt, concrete, etc. A cubic yard is 3 x 3 x 3 = 27 cubic feet.
625 qubic feet
You can measure the surface of the dirt in square yards. That would be nine square feet.However the volume or amount of dirt cannot be measured in square yards or square feet. The amount of dirt in a volume of one cubic yard would be 27 cubic feet. ( 3x3x3=27 )The amount of dirt in a square yard to a depth of 0.5 feet would be 4.5 cubic feet. (3x3x0.5=4.5)

In earth-moving or landscaping terms (which is where the term yard as in volume comes from) 1 yard is actually an abbreviation for 1 cubic yard.

This answer will vary depending on what type of dirt it is, if it is a yard high, or a yard long, or whether there are particles in the dirt that will cause it to be heavier, such as water. But a normal yard high of dirt and I am assuming this as if it is a yard long and high, would be about ten to twenty pounds. This is answered off of the top of my head, so don't think it as 100% correct. Hope I helped you well enough!
yes dirt and gravel are measured the same.

Assuming that the question is being asked about "dirt"; in the United States, the volume of dirt is calculated in cubic yards. In the rest of the world, the volume of dirt is calculated in cubic meters. A cubic yard of dirt is the volume of dirt that fits in a space 1 yard (36 inches) by 1 yard by 1 yard. A cubic meter is 1M X 1M X 1M.
1 square yard of dirt covers up to 9 square feet of ground.
Depends on the type of dirt, what kind of yard you are using, etc... Generally, it will be a couple pounds or so.
This probably their is a mole in your yard. They throw up dirt as they dig underground looking for things to eat.
