What are the two methods used for mining coal?
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
Does an outcrop containing Jurassic dinosaur fossils overlying Pennsylvanian coal deposits represent uninterrupted deposition?
No, the outcrop does not represent uninterrupted deposition. The presence of Pennsylvanian coal deposits indicates a gap in time between the deposition of the coal and the Jurassic dinosaur fossils, suggesting a period of erosion or non-deposition between the two.
What two continents has matching rocks and minerals are found?
North America and Europe have matching rocks and minerals due to the geological history of the continents. Tectonic plates have shifted over time, resulting in similar rock formations and mineral deposits in both regions.
What two names for the process by which soil and rock are stripped from the Earths surface to expose underlying coal?
The two names for this process are surface mining or strip mining. Surface mining involves removing layers of soil and rock to access coal deposits beneath the surface. Strip mining specifically refers to the method of removing layers in strips to expose coal seams.
What two general features do most continents have in common?
Most continents have landmasses with diverse ecosystems and varying geographic landscapes, such as mountains, plains, rivers, and coastlines. Additionally, continents are generally made up of a combination of different countries and cultures, contributing to their unique identities.
What are the two methods used for mining coal?
The two methods used for mining coal are surface mining and underground mining. Surface mining involves removing layers of soil and rock to access coal deposits near the surface, while underground mining involves tunneling underground to extract coal from deeper deposits.
Where is coal energy found?
Coal energy is present in coal. There are two types of coal: bituminous, or 'soft' coal, and anthracite coal, or hard coal. Coal is a hard rocky substance that is the left-over carbon from huge amounts of plants from ages past which died, and have been covered over by sometimes thousands of feet of rock and dirt.
What are the two methods used to mine coal out of the ground so that you can use it to make electricity?
The two methods used to mine coal are surface mining and underground mining. Surface mining involves removing topsoil and rock layers to access coal deposits near the surface, while underground mining involves tunneling deep beneath the ground to extract coal deposits.
Why has the cost of coal risen?
There are two reasons for the cost of coal to rise. First, inflation causes the cost of everything to rise. Secondly, in mining, you extract the easiest deposits first, and as they are exhausted, you mine the more difficult deposits, which cost more to extract. People have mined coal for thousands of years, and we are gradually going deeper and deeper.
What two continents have a billion people?
Asia and Africa have over a billion people each, making them the two most populous continents in the world.
Which two continents have the most islands?
Asia North America
What are the two continents with the most dense populations?

On what two continents is Arabic spoken the most?
Asia and Africa.
What are the two most abundant resources in Eastern Central Europe?
The two most abundant resources of Eastern Central Europe are coal and forests.
What two continents had the most European empres established on them?
Africa and Asia
Can crude oil be found in coal?
No, crude oil is typically found in porous rock formations while coal forms from the compression of plant material over millions of years. The two resources have different origins and compositions, so crude oil is not found within coal deposits.
Which two continents do not have any of the top most popular countries in the world?
Antarctica and Oceania are the two continents that do not have any of the top most popular countries in the world in terms of population, economy, or global influence.
