I'll be glad to check your answers.
is number 2, a?
Yeah it is.
1. The Cenozoic Era is also referred to as the Age of Mammals. To answer this question, we can recall some basic knowledge about geological eras. The Cenozoic Era is the most recent major division of Earth's history and is characterized by the dominance of mammals. The Age of Fish refers to the Paleozoic Era, while the Age of Dinosaurs refers to the Mesozoic Era. The First Era is not a commonly used term to describe the Cenozoic Era, so the correct answer is A. Age of Mammals.
2. When new clay sediment is deposited on top of old beach material, it's known as a Transgression. To answer this question, we need to understand the terms related to sedimentation and coastal processes. In geology, a Transgression occurs when the sea level rises, leading to the deposition of younger sediments on top of older sediments. Regression, on the other hand, refers to the opposite process where the sea level falls and exposes older sediments. Progression and Aggression are not terms used to describe these processes, so the correct answer is A. Transgression.
3. Small fragments of orbiting bodies that have fallen on Earth's surface are known as Meteorites. To answer this question, we should be familiar with the different types of celestial bodies and their terminology. Asteroids are rocky objects that orbit the Sun, while meteorites are fragments of those asteroids that survive their passage through the Earth's atmosphere and reach the surface. Zirconium and Uranium are chemical elements, not directly related to fallen celestial fragments, so the correct answer is B. Meteorites.
4. The ancient geographic setting of an area is known as its Paleogeography. To answer this question, we can break down the term and knowledge of geography and geology. Geo means Earth, and graphy refers to the description or study of something. Paleogeography, therefore, is the study or description of the ancient geography or past geographic setting of an area. Passive margin refers to a tectonic plate boundary, transgression relates to sea-level rise, and phytoplankton is a type of marine algae. None of these terms directly describe the ancient geographic setting, so the correct answer is A. Paleogeography.
5. The oldest and most stable part of a continent is known as a Craton. To answer this question, we need to understand the geological structure of continents. A Craton is a large and stable part of the Earth's continental crust that has remained relatively unchanged for billions of years. Crust refers to the outer layer of the Earth, Pluton is a type of igneous intrusion, and Shield usually refers to an exposed portion of a Craton. However, the most specific answer that matches the description is C. Craton.
