Answer:
B. Geothermal refers to heat sources on the Earth’s crust
Explanation:
- The geothermal energy is the heat that is derived from the storing of energy that creates by the earth's temperature and the earth's crust is origin for this type of energy along with the radioactive decay of the elements of the crust.
- <u>Thus said to be earth's internal heat and needs to be trapped as it can get lost during the formation stages. </u>
- The temperature that occurs at the earth's core and the metal zone reaches up to 4000°C and thus the high temperature causes the rocks to melt and give rise to the temperature in the plastic mantle to get activated by the convection currents that reach the surface.
- Some examples of this geothermal energy are those of the hot spring and the rising lava or the magmas.
Answer:
Maps and globes are drawn to scale and use symbols to represent topography and other features on Earth's surface. Grid lines on maps and globes are often used, with lines curving because the Earth is a sphere. The baselines for measuring distance on Earth are the equator and the Prime Meridian. Satellites are also often used as a mean to graph.
Answer:
Layer D
Explanation:
The rock layer with remains of organisms least similar to present day form can be found in Layer D.
Since layer D is the oldest layer, it will contain the oldest fossil in the undisturbed sequence.
This is because of the principle of fossils and fauna succession.
The principle states that "fossils and fauna succeed on another in a definite order".
- Therefore, the oldest rock layer should contain the oldest fossil which is layer D.
- Layer A is the youngest layer and its fossils will be very similar to those of present day.
- So, the older a rock layer, the more farther it will be in resemblance to present day organisms.
Option D which denotes layer D is the right choice.
Answer:
It´s because of the lack of the gravity factor that´s present on the surface of Earth. This makes bodies and objects so light and they practically float in the station´s interior. Earth´s gravity is simply weaker the further you are from it.
Explanation:
Answer:Mid Atlantic ridge
And mountain ranges
Explanation:
The mid Atlantic ridge shows seafloor spreading and alignment continental such as south America to Africa shows that the continent fit together or the animals dispersed across them. The mountain ranges like the Appalachian or British aisle
