Which of the following landforms is not made by groundwater erosion?
A. stalactites
B. stalagmites
C. mountains
D. sinkholes
Answers
Answer:
mountains?
Explanation:
Answer: Mountains
Explanation: Groundwater erodes rock beneath the ground surface, especially carbonate rock. Groundwater deposits material in caves to create stalactites, stalagmites, and columns. And we know that a sink whole is also known as a cenote, sink, sink-hole, swallet, swallow hole, or doline, is a depression or hole in the ground caused by some form of collapse of the surface layer. Most are caused by karst processes – the chemical dissolution of carbonate rocks or suffosion processes

What’s 2 similarities and 2 differences between the Earths layers and the atmospheric layers?
Answers
Answer:
Atmosphere layers. Earth's atmosphere is divided into five main layers: the exosphere, the thermosphere, the mesosphere, the stratosphere and the troposphere. The atmosphere thins out in each higher layer until the gases dissipate in space.
Explanation:
The atmosphere has 4 layers: the troposphere that we live in near the surface of the earth; the stratosphere that houses the ozone layer; the mesosphere, a colder and lower density layer with about 0.1% of the atmosphere; and the thermosphere, the top layer, where the air is hot but very thin.

Explanation:
I don't think it is fair that Watson and Crick were credited with the discovery when so many other scientists were involved because all other scientists also contributed in the work and work harder for it so the credit must be given to all scientists.

Which of the statements are characteristics of a good hypothesis? -is developed from data that cannot be replicated -relies heavily on cutting edge technology -is created from careful research and logical reasoning -is based only on a presentation by an expert in the field -is able to be tested using validated techniques
Answers
Answer:
is created from careful research and logical reasoning
is able to be tested using validated techniques
Explanation:
A hypothesis can be defined as a prediction/expectation that is made in order to understand a phenomenon from the real world. This prediction must be testable and measurable by using the scientific method. In science, a good hypothesis clearly defines the relationships between two or more variables (independent variables and dependent variables). Moreover, a good hypothesis must also be written in simple and precise language, which means that its statements must be understandable (and verifiable) for any person and/or researcher working in the field.
