Fossils help scientists date rocks: True
Sometimes younger rock layers are found beneath older rock layers: True, because it happens with landslides and other causes.
No fossils from the Precambrian era have been found because there were no organisms at the time: False because there were organisims like algae and bacteria, and there are a very small amout of fossils from that era.
The map of Earth has changed over millions of years, but is now set: False
The correct answer is that all of them are examples of checks and balances!
Checks and balances allow one branch of the government to check on another one. For example the executive branch can check on the judicial (A), the judicial branch can check on the executive (B), the judicial branch can check on the executive (C) and the juidicial branch can check on the executive (D).
Answer:
This statement is true since the formation of this ocean arose 200 million years ago, making it the last in shape during the division of the Pangea supercontinent.
Pangea began to fragment due to the force of Earth's tectonic plates, separating the ancient continent of America and leaving a large body of water in between.
Explanation:
The second major phase of Pangea's disintegration began at the beginning of the Cretaceous (150-140 million years ago), when the supercontinent Gondwana divided into four smaller continents (Africa, South America, India, and Antarctica / Australia).
Answer:
The Andes are more epic than the Rockies. The Andes are higher, and the Andes are longer. So, based on those objective criteria, the Andes wins
Explanation:
Answer:
Explanation:
Answer 1: The bulk density also called as the apparent density or volumetric density. It is a property of the granules, powders and other solids. It is used in the reference of mineral components, foodstuff, chemical substances and any other corpuscles. The sand, organic matter and clay are the materials which can increase the bulk density of the soil. The density is directly proportional to the mass of the body.
The porosity or percentage pore space can be define as the portion of the soil volume that is occupied with the pore space. The pore spaces of the soil will reduce due to the particles added in the soil will accumulate the pore spaces of the soil.
Answer 2: The particle density can be define as the density of the solid particles that make up the soil sample. The value of this is expressed in terms of gram per cubic centimeters. Since the pore spaces in the soil are filled with the materials which will increase the mass of the soil. Thus the accurate bulk density of the soil cannot be measured.
