Answer:
According to the fossil record, life on Earth evolved 3.5-4.28 billion years ago in the form of what? Primitive bacteria that lived in rocks on the deep ocean floor. To investigate the origins of life on Earth, scientist Stanley Miller set up an experiment.
answer: Primitive bacteria
Explanation:
B. North Sea, it is well known for its fierceness. Throughout the year there are strong storms that hit the coasts of the countries that surround it.This huge raft of seawater of about 750,000 square kilometers, an "arm of the Atlantic" we could say, receives marine currents from the other side of the world and is stirred up affecting the British Isles, Norway, Denmark, Germany, Holland, Belgium and France with big tides and scary storms.
Pretty much Saudi Arabia, Iran, Iraq, Syria.
Answer:
Porosity.
Explanation:
Describes the volume of void space in a rock, whereas POROSITY describes how easily fluid can flow through the rock.
I hope it helps! Have a great day!
Answer:
elastic deformation: the rock returns to its original shape when the stress is removed.
plastic deformation: the rock does not return to its original shape when the stress is removed.
fracture: the rock breaks.
Explanation:
Stress is the force applied to an object. In geology, stress is the force per unit area that is placed on a rock. Four types of stresses act on materials.
A deeply buried rock is pushed down by the weight of all the material above it. Since the rock cannot move, it cannot deform. This is called confining stress.
Compression squeezes rocks together, causing rocks to fold or fracture (break) (figure 1). Compression is the most common stress at convergent plate boundaries.
Rocks that are pulled apart are under tension. Rocks under tension lengthen or break apart. Tension is the major type of stress at divergent plate boundaries.
When forces are parallel but moving in opposite directions, the stress is called shear (figure 2). Shear stress is the most common stress at transform plate boundaries.
Stress In Earth’s Crust
Enormous slabs of lithosphere move unevenly over the planet’s spherical surface, resulting in earthquakes. This chapter deals with two types of geological activity that occur because of plate tectonics: mountain building and earthquakes. First, we will consider what can happen to rocks when they are exposed to stress.
