1.
a narrow piece of land that connects two larger pieces of land.
Correct Answer
B. Isthmus
Explanation
An isthmus is a narrow piece of land that connects two larger pieces of land. It is a geographic feature that can be found between two bodies of water, such as two seas or two oceans. Isthmuses are often important for transportation and trade, as they provide a shorter route between two larger land masses. They can also have significant ecological and environmental implications, as they can impact the flow of water and the movement of species between different areas.
2.
the study of the earth in all its variety.
Correct Answer
B. GeograpHy
Explanation
Geography is the study of the earth in all its variety, including the moon. It encompasses the examination of the physical features, climate, and ecosystems of the earth, as well as the human activities and their impact on the planet. The study of geography also involves understanding the spatial relationships between different regions, including the moon, and how they interact with each other. Therefore, geography is the correct answer as it encompasses the study of the earth and its various aspects, including the moon.
3.
number of degrees that the earth is tilted on its axis.
Correct Answer
A. 23 1\2
Explanation
The correct answer is 23 1/2. This refers to the number of degrees that the Earth is tilted on its axis. The Earth's axis is tilted at an angle of approximately 23.5 degrees relative to its orbit around the Sun. This tilt is responsible for the changing seasons and the variation in daylight hours throughout the year.
4.
The highest spot on earth.
Correct Answer
E. Mt.everest
Explanation
Mt. Everest is the correct answer because it is the highest spot on earth. It is located in the Himalayas and has an elevation of 29,029 feet (8,848 meters). The peak of Mt. Everest is known as the "roof of the world" and is a popular destination for mountaineers and adventurers. It is renowned for its challenging climbing conditions and extreme weather. Mt. Everest holds a significant place in mountaineering history and is considered a symbol of human achievement and perseverance.
5.
the flat area at high elevation.
Correct Answer
C. Plateau
Explanation
The correct answer is plateau because a plateau refers to a flat area at a high elevation. A mountain is a tall, elevated landform with steep sides, while the Mariana Trench is the deepest part of the world's oceans, not a flat area. Therefore, the best fit for the given description is a plateau.
6.
the lowest spot on earth.
Correct Answer
A. Marianna trench
Explanation
The Mariana Trench is the lowest spot on Earth, located in the western Pacific Ocean. It reaches a depth of about 36,070 feet (10,994 meters) and is known for its extreme pressure and darkness. This trench is formed by the collision of two tectonic plates, making it a significant geological feature. The other options, such as a dumpster or plateau, do not accurately describe the lowest spot on Earth.
7.
steep-sided lowland formed by a river cutting a plateau.
Correct Answer
A. Canyon
Explanation
A steep-sided lowland formed by a river cutting a plateau is known as a canyon. Canyons are typically characterized by their deep and narrow valleys, which are carved out by the erosive action of rivers over millions of years. As the river flows through the plateau, it gradually erodes the surrounding rock and creates a deep, narrow gorge with steep sides. Canyons can be found in various parts of the world, and they often offer breathtaking natural landscapes and geological formations.
8.
Changes caused by the earth year-long orbit.
Correct Answer
D. Seasons
Explanation
The correct answer is seasons. The changes in seasons are caused by the Earth's year-long orbit around the sun. As the Earth orbits the sun, its axis is tilted, causing different parts of the Earth to receive varying amounts of sunlight throughout the year. This variation in sunlight leads to changes in temperature, weather patterns, and the length of daylight, resulting in the four distinct seasons of fall, winter, spring, and summer.
9.
a cold, rocky sphere with no water or atmosphere.
Correct Answer
C. The moon
Explanation
The given correct answer is "the moon." The moon is described as a cold, rocky sphere with no water or atmosphere. This aligns with scientific knowledge about the moon, as it is a natural satellite of the Earth and lacks the conditions necessary for supporting life. The moon's surface is covered in craters and is composed mainly of rocks and dust. It has no atmosphere, meaning there is no air or water present. Therefore, the moon fits the description of a cold, rocky sphere with no water or atmosphere.
10.
the number of days it takes the earth to travel around the sun.
Correct Answer
C. 365 1\2
Explanation
The correct answer is 365 1/2. This is because it represents the number of days it takes for the Earth to complete one orbit around the Sun, which is approximately 365.25 days. The 1/2 represents the additional half day, accounting for the leap year that occurs every four years to compensate for the slight discrepancy between the calendar year and the actual time it takes for the Earth to orbit the Sun.
